Chapter 17

The Chronology of Genesis 11 — The Postdiluvian Patriarchs and the Missing Centuries

In the previous chapter, we examined the chronology of Genesis 5 — the antediluvian (pre-Flood) patriarchs from Adam to Noah. We saw that the Masoretic Text (MT) has systematically reduced the "begetting ages" of these patriarchs compared to the Septuagint (LXX), compressing the timeline from Creation to the Flood by roughly 600 years. The pattern was unmistakable: in case after case, exactly 100 years had been subtracted from the age at which each patriarch fathered his son of promise. This was not accidental scribal error. It was deliberate editorial work.

Now we turn to Genesis 11, and the story gets even more dramatic. The postdiluvian (post-Flood) genealogy — from Shem's son Arphaxad all the way down to Abraham — shows exactly the same pattern of deflation. And the consequences here are, if anything, more devastating for the MT's credibility. When we compress the time between the Flood and Abraham's birth the way the MT does, we create a series of historical and archaeological impossibilities that the LXX's longer chronology avoids entirely. We also lose the ability to make sense of the biblical narrative itself — the stories of the patriarchs, the Table of Nations, the Tower of Babel, and the calling of Abraham all become strained and difficult when crammed into the MT's impossibly narrow timeline.

This is the chapter where I want to lay out all the data, compare the numbers across every major textual witness, and let the reader see for themselves just how strong the case is that the MT's chronology of Genesis 11 has been tampered with. By the end, I think you'll agree: the missing centuries are real, and somebody took them out on purpose.

The Data: Comparing the Textual Witnesses

Let's start by putting the numbers on the table. Genesis 11:10–26 provides us with the genealogy from Shem to Abraham — ten generations of postdiluvian patriarchs. For each patriarch, the text tells us three things: (1) how old he was when he fathered his son of promise, (2) how many years he lived after that son was born, and (3) his total lifespan. These three numbers — the "begetting age," the "remaining years," and the "total lifespan" — allow us to construct a precise chronology from the Flood to Abraham.

We have four major textual witnesses for these numbers: the Masoretic Text (MT), the Septuagint (LXX), the Samaritan Pentateuch (SP), and the first-century Jewish historian Flavius Josephus, who provided his own chronological data in his Antiquities of the Jews (c. 93 AD). There is also a Latin work called the Liber Antiquitatum Biblicarum (LAB), sometimes attributed to "pseudo-Philo," which preserves an independent chronological tradition. Let me walk you through the key patriarchs and show you the pattern.

Arphaxad

Arphaxad was the son of Shem, born two years after the Flood (Genesis 11:10). The LXX says Arphaxad was 135 years old when he fathered his next descendant. The MT says he was 35. The difference? Exactly 100 years. The total lifespan in both traditions is 438 years — they agree on how long Arphaxad lived, but they disagree on when in his life the next patriarch was born. In the MT, those 100 years were simply moved from the "begetting age" column to the "remaining years" column. The total stays the same. Only the chronological link between generations — the begetting age, which is what determines how long the overall timeline is — has been changed.¹

Cainan — The Missing Patriarch

Before we get to Shelah, we need to talk about one of the most explosive pieces of evidence in this entire debate. The LXX includes a patriarch named Cainan (Kainam, Καϊνάμ) between Arphaxad and Shelah — a man who is completely absent from the MT. According to the LXX, Cainan was 130 years old when he fathered Shelah, and he lived a total of 460 years. This additional generation adds approximately 130 years to the genealogy.²

Why is this so important? Because Luke's genealogy of Jesus includes Cainan. In Luke 3:35–36, we read: "...the son of Serug, the son of Reu, the son of Peleg, the son of Eber, the son of Shelah, the son of Cainan, the son of Arphaxad, the son of Shem, the son of Noah, the son of Lamech..." Luke is following the LXX here, not the MT. As Lanier and Ross point out, "Clearly, Luke is using the Old Greek as his written source for the genealogy. It is possible that the Greek contains an earlier and better text and that somehow 'Cainan' was accidentally lost in the Masoretic tradition."³

Henry B. Smith Jr. and Kris Udd have published detailed research confirming the antiquity of Cainan's inclusion in the LXX text. As S. Douglas Woodward notes in summarizing their findings, the oldest manuscript fragment of the LXX — the Berlin Genesis Fragment (Papyrus 911, dated to the late third century AD) — includes Cainan in Genesis 11:13. Furthermore, the early church father Hippolytus, writing in Rome around AD 222 — before our earliest manuscripts of the LXX — cited Genesis 11:12–14 with Cainan explicitly included: "And Arpachshad lives 135 years, he fathered Kainan. And Kainan lived 130 years and he fathered Shelah."⁴

We are on very shaky ground if we try to argue that Cainan was a later addition to the LXX. The manuscript evidence and the patristic evidence both confirm his presence in the earliest accessible texts. And Luke settles the matter for any Christian who takes the New Testament seriously.

Some defenders of the MT have tried to dismiss Luke 3:36 by arguing that a later scribe inserted "Cainan" into Luke's genealogy to harmonize it with the LXX. But this argument is circular — it assumes the MT is correct in order to argue that Luke's text was corrupted, and then uses the "corrected" Luke to argue that the LXX is wrong. The simplest explanation is the one that the manuscript evidence supports: Luke followed the LXX because the LXX preserved the correct genealogy, including Cainan. And the MT dropped Cainan because the second-century editors wanted to remove an entire generation from the chronology — gaining an additional 130 years of compression.

I want to emphasize how significant this is. We're not dealing here with a minor textual variant — a different spelling of a name or a slightly different number. We're dealing with an entire human being who has been erased from the genealogical record. A patriarch — a link in the chain from Shem to Abraham, a man in the lineage of Jesus Christ — has been deleted from the Hebrew text. And the only reason we know about it is because the LXX preserved him, and because Luke, guided by the Holy Spirit, included him in the genealogy of our Lord. If we needed a single piece of evidence to demonstrate that the MT's Genesis 11 text has been tampered with, the case of Cainan would be more than sufficient.

Shelah

Shelah — the son of Cainan in the LXX, or the son of Arphaxad in the MT. The LXX says Shelah was 130 years old when Eber was born. The MT says 30. The difference? Once again, exactly 100 years. The total lifespans are very close in both traditions (the LXX has 433 years; the MT also has 433).⁵

Eber

The LXX says Eber was 134 years old when Peleg was born. The MT says 34. Exactly 100 years difference. The total lifespans agree at 464 years.⁶

Peleg

The LXX says Peleg was 130 years old when Reu was born. The MT says 30. Again — exactly 100 years. The lifespans differ here: the LXX gives 339 years, the MT gives 239 years. In this case, the MT has also subtracted 100 years from Peleg's total lifespan, not just his begetting age.⁷

Reu

The LXX says Reu was 132 years old when Serug was born. The MT says 32. One hundred years difference. The LXX gives a lifespan of 339 years; the MT gives 239. Again, 100 years subtracted from both the begetting age and the lifespan.⁸

Serug

The LXX says Serug was 130 years old when Nahor was born. The MT says 30. One hundred years. The LXX gives a lifespan of 330 years; the MT gives 230. The same 100-year reduction across the board.⁹

Nahor — The Telltale Exception

Now here is the clincher. Nahor — Abraham's grandfather — is the one patriarch where the pattern changes. The LXX says Nahor was 79 years old when Terah was born. The MT says 29. That's a difference of only 50 years, not 100.

Why only 50? Because 100 years subtracted from 79 would give us negative 21. Nahor would have fathered Terah 21 years before he himself was born. As Woodward observes, "that would have been no mean trick!"¹⁰

This point was recognized and emphasized by Smith, who called it the "smoking gun" for deflation rather than inflation. If someone were inflating the numbers in the LXX, they would have had no reason to add only 50 years to Nahor instead of 100. But if someone were deflating the numbers in the MT, they would have had to stop at 50 for Nahor to avoid a chronological impossibility.¹¹

Terah

The question of Terah's age when Abraham was born is important and sometimes debated. Genesis 11:26 says, "When Terah had lived 70 years, he fathered Abram, Nahor, and Haran." At first glance, this seems to say Terah was 70 when Abraham was born. But as several scholars have shown, Abraham was not Terah's firstborn — he is listed first because of his importance, not his birth order. Genesis 11:32 tells us Terah lived to 205 years, and Genesis 12:4 says Abraham was 75 when he left Haran — which Stephen confirms happened after Terah's death (Acts 7:4). Working the math: 205 minus 75 equals 130. So Terah was actually 130 years old when Abraham was born. As Jeremy Sexton notes, "The Bible displays its chronological meticulousness here."¹²

A Summary Table

Let me present the postdiluvian patriarchs in a simple table so we can see the full picture at a glance. The "Begetting Age" is the age at which each patriarch fathered his son of promise — the next link in the chain leading to Abraham. The "Difference" column shows how many years the MT subtracted compared to the LXX.

Adding up the begetting ages gives us the total number of years between the birth of Arphaxad (two years after the Flood) and the birth of Abraham. In the LXX, this sum is approximately 1,132 years. In the MT, it is approximately 292 years. The difference is a staggering 840 years — over eight centuries that have vanished from the MT.¹³

The Mathematical Precision Is Damning

Let me say this as plainly as I can. The consistent subtraction of exactly 100 years from patriarch after patriarch — Arphaxad, Shelah, Eber, Peleg, Reu, Serug — cannot be the result of accidental scribal error. Scribal errors are random. They produce irregular, unpredictable variants. A scribe who accidentally miscopied one number would not accidentally miscopie the next six numbers by exactly the same amount. And a scribe who accidentally changed a number would not also accidentally adjust the "remaining years" to keep the total lifespan consistent (as happens in several of these patriarchs).

What we see in the Genesis 11 chronology is not random error. It is systematic, mathematically precise editorial activity. Somebody sat down with the text and subtracted 100 years from the begetting age of each patriarch, adjusting the remaining years where necessary to preserve the total lifespan. When they got to Nahor, they realized they could only subtract 50 years without creating an absurdity — so they subtracted 50 instead. And they omitted the entire generation of Cainan to remove an additional 130 years.

To put this another way: if you were a second-century rabbi who wanted to shorten the biblical timeline by as many years as possible, you would do exactly what the MT does. You would subtract a round number — 100 years — from each begetting age. You would keep the total lifespans the same (or close to the same) so that the change was less obvious. You would make an exception for Nahor (where 100 years wouldn't work) and subtract only 50 instead. And you would delete Cainan entirely to pick up an extra 130 years. The MT's numbers read like a carefully planned operation, not like the result of careless copying.

This is deliberate. This is intentional. And as we argued in Chapter 12, there is strong historical evidence that the second-century rabbinic establishment under Rabbi Akiba and his circle had both the motive and the opportunity to carry out exactly this kind of textual revision.

Josephus and the Liber Antiquitatum Biblicarum Confirm the LXX

If the MT's shorter numbers were original, we would expect the earliest Jewish historians to follow them. But they don't. Both Josephus and the Liber Antiquitatum Biblicarum (LAB) — written in the first century AD, before the rabbinic standardization of the proto-MT — follow the LXX's longer chronology.

Josephus is especially important. He was a first-century Jewish historian who had access to the Temple archives in Jerusalem before the Temple was destroyed in AD 70. He was a well-connected Pharisee with access to the best Hebrew manuscripts available. And yet his chronological numbers follow the LXX, not the proto-MT. Josephus explicitly stated that his Antiquities covered a history of approximately 5,000 years — a figure consistent with the LXX chronology but completely impossible if we follow the MT, which yields only about 4,000 years from Creation to Christ.¹⁴

As Woodward emphasizes, Josephus also made a very telling statement: he claimed that he himself had translated the Hebrew text into Greek — not by referencing the LXX, but from his own Hebrew sources. "These antiquities contain the history of 5,000 years; and are taken out of our sacred books but translated by me into the Greek tongue," Josephus wrote. Since his begetting ages and remaining years match the LXX and not the proto-MT, he must have been working from a copy of the Hebrew that still preserved the longer chronology — a Hebrew text that predated Akiba's revisions.¹⁵

The Liber Antiquitatum Biblicarum tells the same story. This Latin work, likely composed sometime around AD 50–75, also preserves the longer chronology. Like Josephus, it was completed decades before the rabbinic standardization was carried out. Together, Josephus and LAB constitute powerful independent witnesses that the LXX's numbers were still the accepted Hebrew chronology in the first century.¹⁶

The Samaritan Pentateuch — A Complicated Third Witness

The Samaritan Pentateuch (SP) provides a third textual witness for the Genesis 11 chronology, though the picture here is more complicated. The SP's numbers sometimes agree with the LXX against the MT, and sometimes they fall between the two. In several cases, the SP gives higher begetting ages than the MT — confirming that the MT's numbers are the outlier — but not always as high as the LXX.

Woodward and Smith have argued that the SP's chronological numbers in Genesis 5 and 11 were influenced by the Book of Jubilees (c. 150 BC), which had its own chronological system based on jubilee cycles. Smith notes that several scholars have documented the "many affinities" between the SP and Jubilees, and at least one PhD dissertation has argued that "the Genesis 5 SP was derived from Jubilees itself."¹⁷ If this is correct, then the SP's chronological numbers represent a third tradition — neither the original LXX/Hebrew numbers nor the later MT numbers, but a Jubilees-influenced revision. This means we should not expect the SP to perfectly match the LXX, but the fact that it is frequently closer to the LXX than to the MT is still significant evidence against the MT's numbers.

Where the SP does agree with the LXX against the MT — which happens in several of the postdiluvian patriarchs — we have independent confirmation from a textual tradition that separated from the mainstream Jewish text very early. The SP was maintained by the Samaritan community, which had no contact with the Alexandrian Jewish community that produced the LXX. When two independent witnesses both disagree with the MT, the cumulative evidence against the MT is very strong.

The Absurdity of the MT's Compressed Timeline

Now let's talk about what the MT's chronology actually implies — because when we follow the MT's numbers, we run into a series of historical absurdities that the LXX chronology avoids entirely.

Shem Outlives Abraham

This is one of the most striking problems. In the MT chronology, Shem — the son of Noah, the man who survived the Flood — is still alive during the lifetime of Abraham. In fact, by the MT's numbers, Shem outlives Abraham. Shem is alive during the time of Abraham, Isaac, and even Jacob.

Stop and think about that for a moment. Shem walked with Noah. He saw the Flood. He lived through the most catastrophic event in human history. And according to the MT, he was still alive when Abraham was called out of Ur, when Isaac was born, and when Jacob was wrestling with the angel at Peniel.

If this were true, why does the Bible never mention it? Why is Shem completely absent from the stories of the patriarchs? Why doesn't Abraham ever visit Shem — the man who walked with Noah, who could tell him about the world before the Flood, who had received blessing directly from God (Genesis 9:26)? The silence is deafening. Some later Jewish sources, like the Book of Jasher, tried to fill this gap by having Abraham study under Shem. But this feels more like a patch to cover an awkward problem than a genuine historical memory.¹⁸

As Woodward notes, in the MT chronology, Abraham lives at the same time as ten generations of his predecessors. Eight or nine of the ten generations before him are still alive as his contemporaries, and nine of the ten live longer lives than Abraham. God promises Abraham a long life — but by the MT's reckoning, practically everybody who came before him is still around, living even longer. This doesn't make narrative sense. It doesn't make theological sense. And it raises an obvious question: if all these patriarchs were still alive, why did God need to call Abraham specifically to begin a new thing?¹⁹

The LXX chronology solves this problem completely. With over 1,100 years between the Flood and Abraham's birth, Shem and the other early postdiluvian patriarchs have long since died before Abraham is born. Abraham is not surrounded by ancient survivors of the Flood. He is separated from Noah's world by a millennium — which is exactly what the biblical narrative seems to assume.

Consider the weight of this argument carefully. When God calls Abraham in Genesis 12, the text presents this as a dramatic new beginning in the history of redemption. God is starting fresh with one man from Ur of the Chaldeans. He is calling Abraham out of a pagan world — a world that has lost its way, a world that has forgotten the God who made it. The entire theological thrust of the Abrahamic narrative depends on the idea that Abraham is entering new territory, receiving new promises, being set apart from a world that has gone astray.

But if Shem is still alive during Abraham's lifetime — if ten generations of Noah's descendants are walking around as Abraham's contemporaries — then the theological drama is dramatically weakened. Why does God need to call Abraham if Shem is right there? Why doesn't the narrative mention Abraham seeking out Shem — the man who received Noah's blessing, who carried the faith through the Flood, who had direct access to the pre-Flood world? The silence makes no sense in the MT's compressed timeline. In the LXX's longer timeline, the silence makes perfect sense: Shem is ancient history by the time Abraham is born. The knowledge of God has been diluted over a thousand years. The nations have scattered and forgotten. Now God calls Abraham. Now the new beginning makes theological sense.

The Table of Nations and the Rise of Civilizations

The second major problem with the MT's compressed timeline involves the Table of Nations in Genesis 10 and the archaeological record of early civilizations.

Genesis 10 describes how the descendants of Noah's three sons — Shem, Ham, and Japheth — spread out across the earth and became the nations of the ancient world. This chapter describes a massive process of migration, settlement, and cultural development. The peoples described in Genesis 10 founded the great civilizations of Mesopotamia, Egypt, the Indus Valley, and beyond. Languages diverged, cultures developed, cities were built, empires rose.

In the MT chronology, all of this must happen within roughly 290 years between the Flood and Abraham's birth. That's less than three centuries for the following events to occur: (1) the repopulation of the earth from Noah's three sons and their wives; (2) the migration of peoples across thousands of miles; (3) the building of the Tower of Babel and the subsequent scattering of languages; (4) the rise of ancient Egyptian civilization, including the first dynasties of pharaohs; (5) the emergence of Sumerian civilization in Mesopotamia; (6) the development of writing, irrigation, monumental architecture, organized religion, and complex social structures.

This is impossibly compressed. Let me put this in perspective. Two hundred and ninety years is roughly the same span of time as from the founding of the United States to the present day. Now imagine compressing into that same period the following: the entire human race growing from eight people to millions, migrating from a single location in the ancient Near East to populate three continents, developing dozens of distinct languages and cultures, inventing writing independently in at least two locations, building cities and irrigation systems, establishing monarchies and dynasties, developing metallurgy and trade networks, and constructing monumental architecture including ziggurats and early pyramids. All of this, from a starting population of eight. In under three centuries. It simply does not work.

We know from archaeology that the great civilizations of the ancient Near East — Egypt, Sumer, the Indus Valley — were already well established by 3000 BC. Even if we use the most conservative archaeological dates, these civilizations required centuries of development. Population growth alone, starting from eight people, would require many generations to produce the populations needed for city-building. And cities don't spring up overnight — they develop gradually from villages to towns to urban centers over hundreds of years. The MT's 290-year window simply does not provide enough time.²⁰

The LXX's chronology, with over 1,000 years between the Flood and Abraham, provides ample time. In the LXX framework, the Flood can be placed in the late fourth or early fifth millennium BC (Woodward calculates approximately 3358 BC, though other calculations yield slightly different dates). This gives humanity over a thousand years to migrate, settle, develop languages and cultures, and build the great civilizations that were already flourishing by the time of Abraham (c. 2200–2000 BC).²¹

The Tower of Babel

The Tower of Babel event (Genesis 11:1–9) must be placed chronologically between the Flood and the dispersal of nations described in Genesis 10. In the MT timeline, this event must occur within the first generation or two after the Flood — perhaps within 100 years of the Flood itself. This means that only a few generations after the entire human race was reduced to eight people on a boat, humanity had already multiplied enough to build a city with a massive tower, developed a single unified language and culture, and had enough people to be "scattered" across the face of the whole earth.

In the LXX timeline, the Tower of Babel can be placed 200 or more years after the Flood — giving humanity several centuries to multiply and develop before the scattering. Woodward places the Babel event at approximately 3159 BC, around 200 years after the Flood in his LXX-based chronology. This is far more plausible than the MT's timeline, which requires the entire sequence — from eight survivors to a populated city with a towering monument — to unfold within a single century.²²

Nimrod and the Chronological Tangle

The case of Nimrod is another place where the MT's compressed chronology creates problems. Genesis 10:8–12 describes Nimrod, the son of Cush, as a mighty hunter and the founder of great cities in both Mesopotamia and Assyria — including Babel, Nineveh, and others. Nimrod is clearly one of the most important figures in the Table of Nations, and his historical footprint (which many scholars connect to various legendary figures in ancient Near Eastern history) suggests a long and powerful reign.

In the MT chronology, various commentators have tried to make Nimrod a contemporary of Abraham — which would place Nimrod's activities quite late. But as Woodward demonstrates, the LXX chronology tells a different story. In the LXX framework, Nimrod was born around 3100 BC (since his father Cush was among the first post-Flood generation) and lived approximately 300–400 years. This places Nimrod's death around 2700 BC — roughly 600 years before Abraham's birth (c. 2228 BC in Woodward's calculation). Nimrod and Abraham were not contemporaries.²³

This matters because it helps us make better sense of both the biblical narrative and the archaeological record. The great cities attributed to Nimrod — Babel, Erech, Akkad, Nineveh — correspond to some of the earliest urban centers in Mesopotamia. Archaeology places the earliest phases of these cities in the fourth and third millennia BC. The LXX chronology puts Nimrod right in this time frame. The MT's chronology forces Nimrod's city-building activities into an impossibly narrow window and creates the false impression that he was Abraham's contemporary.

The Seder Olam — The Vehicle of Chronological Compression

We've now seen what was changed in the Genesis 11 chronology. The next question is: how was it done, and why?

As we discussed in Chapter 12, there is strong evidence that the second-century rabbinic establishment — led by Rabbi Akiba and his circle — carried out a systematic revision of the Hebrew text of the Old Testament. This revision had multiple goals: weakening Messianic prophecies that Christians applied to Jesus, invalidating the Septuagint (which had become the Christian Old Testament), and compressing the biblical chronology.

The Seder Olam Rabbah — the "Great Order of the World" — was the primary vehicle for this chronological compression. This Jewish chronological work is attributed to Rabbi Yose ben Halafta, a student of Rabbi Akiba, writing around AD 160. The Seder Olam provides a chronology of world history from Creation to the Bar Kokhba revolt (AD 132–135). And its chronological numbers match the MT's compressed chronology — not the LXX's longer one.²⁴

But the Seder Olam didn't just compress Genesis 5 and 11. It also compressed the Persian period of biblical history — and this is where the connection to Daniel's prophecy becomes explosive.

Daniel's Seventy Weeks and the Persian Chronology

Daniel 9:24–27 contains one of the most important Messianic prophecies in the Old Testament — the prophecy of the "seventy weeks." The angel Gabriel tells Daniel that "seventy weeks" (seventy units of seven years, or 490 years) are decreed from the issuing of a decree to restore and rebuild Jerusalem until "Messiah the Prince." If we begin counting from the decree to rebuild Jerusalem (traditionally identified with the decree of Artaxerxes I in 458 or 445 BC), the 490 years bring us to approximately AD 30 — the time of Jesus's ministry and crucifixion.²⁵

This chronological alignment was devastating for the rabbinic opponents of Christianity. Daniel's prophecy pointed directly to Jesus of Nazareth as the Messiah. Something had to be done.

Think about how powerful this must have been in the early decades of Christianity. Christian evangelists could stand up in a synagogue and say, "Daniel prophesied that the Messiah would come 490 years after the decree to rebuild Jerusalem. Count the years. The decree was issued under Artaxerxes. Count forward 490 years. You arrive at the exact time of Jesus of Nazareth — His ministry, His death, His resurrection. Daniel told us exactly when the Messiah would come, and Jesus came at precisely that time." This was a devastatingly effective argument, and the rabbis knew it.

The Seder Olam's solution was to compress the Persian period. Accepted history — based on Greek, Persian, and Babylonian records — recognizes approximately 207 years of Persian rule (from Cyrus the Great's conquest of Babylon in 539 BC to Alexander the Great's defeat of Darius III in 331 BC), spanning thirteen Persian kings. The Seder Olam reduced this period to only 52 years — eliminating eight Persian kings from the historical record and compressing 207 years into roughly one-quarter of their actual length.²⁶

Let that sink in for a moment. The Seder Olam claims the Persians ruled for only 52 years. Every historian — Greek, Persian, Babylonian — agrees it was approximately 207 years. Eight kings were simply removed from the record. This is not a minor calendrical disagreement. This is wholesale historical revision — the ancient equivalent of deleting entries from an encyclopedia to make the dates come out differently.

Why? Because if the Persian period is shortened by approximately 165 years, then Daniel's 490-year countdown no longer ends at the time of Jesus. Instead, it ends in the early second century AD — the time of Bar Kokhba, whom Akiba had proclaimed as the Messiah. As Woodward summarizes, citing J.R. Church: "Yose ben Halafta, student of Rabbi Akiva and admirer of Bar Kokhba, changed the dating so that Daniel's seventy weeks would point to Bar Kokhba as their predicted Messiah, rather than Jesus."²⁷

Even a Jewish scholar — Rabbi Simon Schwab — acknowledged the manipulation. In his book Comparative Jewish Chronology, Schwab admitted that the sages had "covered up a certain historic period and purposely eliminated and suppressed all records and other material pertaining thereto." He suggested that "nothing short of a Divine command" could have motivated these "saintly 'men of truth' to leave out completely from our annals a period of 165 years."²⁸ Christians might differ with Schwab's charitable interpretation of the sages' motives, but the point stands: even Jewish scholarship recognizes that the chronology was deliberately altered.

The "Six Millennial Days" Tradition

There is another important piece of the puzzle that helps explain why the rabbis compressed the chronology. In Jewish tradition — a tradition echoed by several early church fathers — there was a belief that the world would last for 6,000 years before the Messianic age, corresponding to the six days of Creation followed by a Sabbath rest. This was sometimes called the "six millennial days" tradition.²⁹

In the LXX chronology, Jesus was born approximately 5,500 years after Creation — right at the beginning of the sixth millennium, perfectly positioned to inaugurate the Messianic age. Several early church fathers — including Hippolytus, Irenaeus, and others — explicitly used this calculation. The LXX's chronology supported the Christian claim that Jesus came "in the fullness of time" (Galatians 4:4).³⁰

This was a problem for the rabbis. If the world was only about 5,500 years old when Jesus was born, and if the Messiah was expected at or near the 6,000-year mark, then Jesus's timing was suspiciously perfect. The solution was to compress the chronology so that Jesus's birth fell at approximately 3,760 years after Creation — pushing the 6,000-year mark well into the future and arguing that the Messiah had not yet come because the appointed time had not yet arrived.

As Woodward argues, the connection between the Genesis 5 and 11 chronological compression and the "six millennial days" tradition provides one of the strongest explanations for why the rabbis undertook this massive revision. It was not idle tampering. It was targeted, theologically motivated manipulation designed to undercut the most powerful chronological argument the Christians had: that Jesus came at precisely the time prophesied in Scripture.³¹

The result is reflected in the Jewish calendar to this day. The current Jewish calendar year (at the time of this writing, approximately 5786 AM — anno mundi, "in the year of the world") is based on the Seder Olam's compressed chronology. If the LXX chronology is correct, the actual year from Creation should be something closer to 7,500 or above. Over 1,500 years have been removed from world history according to Orthodox Jewish tradition — the combination of approximately 1,386 years removed from Genesis 5 and 11 and approximately 165 years removed from the Persian period.³²

The "Gaps" Debate — Are There Missing Generations?

Before we move on, we need to address an argument that has become very popular in evangelical circles — especially among those who follow the MT but recognize that its compressed timeline creates archaeological problems. This is the argument from "gaps" in the Genesis genealogies.

In 1890, Princeton theologian William Henry Green published an influential article titled "Primeval Chronology" in the journal Bibliotheca Sacra. Green argued that the genealogies of Genesis 5 and 11 were never intended to be used as chronologies. According to Green, the genealogies contain "gaps" — that is, not every generation is listed. Some names have been skipped, and the father-son relationship is actually a grandfather-grandson or even more distant ancestor-descendant relationship. If this is true, then the genealogies cannot be used to calculate a timeline, and the MT's short chronology is not a problem — there could be thousands of additional years hidden in the gaps.³³

Green's argument was enormously influential. B.B. Warfield endorsed it in 1911, writing that it is "precarious in the highest degree to draw chronological inferences from genealogical tables."³⁴ By the early twentieth century, virtually all mainstream evangelical scholars had adopted Green's position. It became the standard way to avoid conflict between the MT's short chronology and the growing evidence from archaeology and Egyptology that human civilizations were far older than Bishop Ussher's 4004 BC date allowed.

But Green's argument has been powerfully challenged by more recent scholarship, and I believe it is fatally flawed. Here's why.

Genesis 5 and 11 Are Unique

Green's argument depends on treating the Genesis 5 and 11 genealogies the same as other biblical genealogies — like the genealogies in 1 Chronicles, or Matthew 1, or Exodus 6. Those genealogies do sometimes skip generations. Matthew 1:8, for example, says "Joram fathered Uzziah" even though Uzziah was actually Joram's great-great-grandson. Three kings have been skipped.

But Genesis 5 and 11 are fundamentally different from these other genealogies. And the difference is the numbers. No other genealogy in the Bible provides the begetting age, the remaining years, and the total lifespan for each individual. As Jeremy Sexton has argued, "I have been unable to find a published interpretation that posits a reason why the author of Genesis 5 and 11 included the begetting ages if not for a chronological purpose."³⁵

Think about it. If the author wanted to provide a genealogy — a list of ancestors — he could have simply listed the names. If he wanted to include lifespans, he could have included lifespans without begetting ages (as Exodus 6:16–20 does for the Levitical genealogy). But he included both begetting ages and lifespans for every single patriarch. The begetting ages serve only one purpose: to allow the reader to calculate the years between generations and construct a timeline. If the author did not intend a chronology, why include the one piece of information — the begetting age — that makes a chronology possible?³⁶

The Grammatical Argument Against Gaps

Sexton has also made a detailed grammatical argument against gaps in Genesis 5 and 11. The Hebrew verb used for "fathered" in these genealogies is yalad (ילד) in the hiphil stem. Green assumed that this verb could mean "became the ancestor of" (i.e., allowing for gaps between the named individual and the next person in the list). But Sexton's careful semantic analysis of the hiphil of yalad throughout the Hebrew Bible demonstrates that when this verb form is used with a named individual as its object, it consistently refers to an immediate parent-child relationship. The grammar of Genesis 5 and 11 does not permit the kind of generational skipping that Green's theory requires.³⁷

The Interlocking Structure

There is another reason gaps cannot work in Genesis 5 and 11. The structure of these genealogies interlocks in a way that prevents insertion of additional generations. Each entry gives us three numbers: the begetting age (A), the remaining years (B), and the total lifespan (A + B = C). If we insert a gap — adding an unnamed generation between, say, Arphaxad and Shelah — then Arphaxad's begetting age (135 in the LXX) no longer connects to Shelah's birth. The mathematical chain is broken. The whole point of the three-number system is that the numbers link together to form a continuous, gapless chronology. As Bernard White has argued, "the numbers are intended to be totaled" and "the generations are contiguous."³⁸

Gaps Don't Actually Solve the Problem

Finally, it's worth pointing out that the "gaps" argument doesn't actually solve the problem it was designed to solve. Green and Warfield proposed gaps to make room for an earth older than Ussher's chronology. But the archaeological evidence for ancient civilizations goes back to approximately 3300–3000 BC for the earliest literate civilizations in Mesopotamia and Egypt. Adding a few gaps — say, doubling the number of generations from ten to twenty — would add perhaps a few thousand years. But evolutionary science claims the human species is hundreds of thousands of years old. As Woodward rightly observes, "Arguing for gaps doesn't even touch the problem of how 'the old earth' and a recent creation (only thousands of years ago) can both be true simultaneously."³⁹

The real solution is not to stretch the MT's chronology with hypothetical gaps. The real solution is to accept the LXX's chronology as original — which provides approximately 5,500 years from Creation to Christ. This timeline fits the archaeological evidence for the earliest civilizations far better than the MT's compressed timeline. It doesn't require us to invent gaps that the text doesn't support. And it aligns with what Josephus, the Samaritan Pentateuch, the Liber Antiquitatum Biblicarum, and the entire patristic tradition all affirm.

J. Paul Tanner published an important article in Bibliotheca Sacra in 2015 in which he analyzed the question of whether gaps are permitted by the text of Genesis 5 and 11. His conclusion — that gaps are not allowed by these passages — is one I agree with. Tanner recognized that the begetting ages create an interlocking mathematical structure that cannot accommodate the insertion of unnamed generations. The numbers are designed to chain together. Remove one link or insert an extra one, and the chain breaks.⁵⁴

I also want to note that the "gaps" approach creates an additional theological problem. If we say there are gaps in the genealogies — unnamed generations between the listed patriarchs — then we're admitting that we don't really know how old the world is. The genealogies become theologically meaningless as timekeeping devices. And if they're meaningless as timekeeping devices, then why did the author go to such extraordinary trouble to include three numbers for every single patriarch? The gaps theory requires us to believe that the most numerically detailed passages in the entire Old Testament were never intended to communicate anything about chronology. That strikes me as deeply implausible.

The Church Fathers and the Longer Chronology

It is also worth noting that the early church universally used the LXX's longer chronology for its calculations of world history. Eusebius of Caesarea (c. 263–339), the father of church history, compiled his famous Chronicon using the LXX's numbers. Julius Africanus (c. 160–240) calculated a world chronology based on the LXX. Theophilus of Antioch (c. 120–185), Origen (c. 185–254), Augustine of Hippo (354–430), the Venerable Bede (c. 673–735) — all of them worked from the LXX's timeline.⁴⁰

Augustine is particularly interesting because he explicitly accepted the LXX's chronology for Genesis 11, including Cainan. In The City of God, Augustine wrote, "Thus the years from the flood to Abraham come to a total of 1072" — a figure that follows the LXX, not the MT (which yields only about 292 years). As Smith has noted, Augustine's "embrace of the LXX's numbers in Gen 11 as representing the original, inspired text is irrefutable."⁴¹

The shift to the MT's chronology in Western Christianity came much later — primarily through Jerome's promotion of the Hebraica veritas (the idea that the Hebrew text should always take priority) and through the Protestant Reformation's wholehearted adoption of the Masoretic tradition (see Chapter 27 for the Jerome vs. Augustine debate, and Chapter 29 for the Reformation's role). Bishop Ussher's famous date of 4004 BC for Creation (published in 1650) was based entirely on the MT's chronology. But Ussher was working against the entire patristic tradition, which had used the LXX's numbers for over a millennium.

Even after Ussher, there were many scholars who continued to advocate for the LXX chronology. As Jeremy Sexton has documented, at least twelve major biblical scholars between the seventeenth and nineteenth centuries — including Vossius, Pezron, Des Vignoles, Hales, Jackson, Faber, Russell, and others — "called for a return to the numbers in the Septuagint."⁴² The triumph of the MT chronology in Protestant scholarship was not inevitable. It was the result of Green's 1890 article, which shifted the conversation away from which chronology was correct and toward the question of whether chronology was possible at all. Once Green persuaded evangelicals that the genealogies couldn't yield a chronology, the question of which numbers were original became moot — and the MT's numbers won by default, simply because they were in the Protestant Bible.

The Archaeological Evidence

The LXX chronology does not just make better sense of the biblical narrative. It also makes better sense of the archaeological record.

Archaeology tells us that the earliest urban civilizations in Mesopotamia (Sumer) and Egypt emerged around 3500–3000 BC. By 3000 BC, Egypt had a unified kingdom under the first dynasties of pharaohs, monumental architecture was being constructed, writing had been developed, and complex social structures were well established. Sumerian civilization in Mesopotamia followed a similar trajectory.

In the MT's chronology, the Flood occurred around 2348 BC (Ussher's calculation). This means that Egyptian civilization — which was already well established by 3000 BC — predates the Flood by over 600 years. The first Egyptian dynasties were building pyramids before Noah built his ark. This is obviously impossible if the Flood destroyed all terrestrial life, as Genesis describes.⁴³

This is not a minor embarrassment for defenders of the MT chronology. It is a fundamental contradiction that has driven many believers away from taking Genesis seriously as history. Young-earth creationists who follow the MT have had to resort to increasingly strained arguments — either claiming that the standard archaeological dating of Egyptian civilization is wildly wrong (by over 600 years), or arguing that the Flood was local rather than global, or proposing exotic theories about how civilizations could spring up almost overnight. None of these solutions is convincing. But the problem itself is an artifact of the MT's compressed timeline. If we use the LXX chronology, the problem simply vanishes.

The LXX's chronology avoids this problem. With the Flood placed in the late fourth millennium BC (approximately 3358 BC in Woodward's calculation) and Creation around 5500–5600 BC, the timeline of early civilizations fits comfortably within the post-Flood period. The earliest urban settlements (c. 3500 BC) begin to appear a few centuries after the Flood — exactly when we would expect them, as the descendants of Noah multiplied and spread out. The rise of Egypt's Old Kingdom (c. 2700–2200 BC) falls well within the period after the Tower of Babel dispersal. The LXX chronology and the archaeological record tell a coherent story.⁴⁴

Woodward devotes extensive attention to this issue in Rebooting the Bible, Part 2, where he works through the detailed correlations between the LXX chronology and the archaeological evidence for early civilizations in Mesopotamia, Egypt, the Indus Valley, and elsewhere. His work demonstrates that when we use the LXX's longer timeline, the so-called "conflicts" between the Bible and archaeology largely disappear. The conflicts are artifacts of the MT's compressed chronology — not problems with the Bible itself.⁴⁵

The Combined Impact: Genesis 5 and Genesis 11 Together

When we combine the chronological compression in Genesis 5 (treated in Chapter 16) with the compression in Genesis 11, the total scale of the alteration becomes staggering.

In Genesis 5, the MT removes approximately 600 years from the pre-Flood chronology compared to the LXX. In Genesis 11, the MT removes approximately 840 years from the post-Flood chronology. That's a combined total of approximately 1,440 years removed from the biblical timeline through the systematic reduction of patriarchal begetting ages — twelve subtractions of 100 years, one subtraction of 50 years, and the elimination of one entire generation (Cainan, accounting for 130 additional years).

Add to this the approximately 165 years removed from the Persian period by the Seder Olam, and the total chronological compression exceeds 1,600 years. Over sixteen centuries of world history have been erased from the MT-based timeline. The current Jewish calendar reflects this erasure: the year 5786 AM should more accurately be something like 7,300–7,500 AM.⁴⁶

Connecting the Chronology to the Broader Thesis

Before we close this chapter, I want to step back and connect what we've found here to the broader argument of this book.

The alteration of the Genesis 5 and 11 chronology is not an isolated phenomenon. It is part of the same program of textual revision that altered the Messianic prophecies — a program we documented in Chapters 14 and 15. The same second-century rabbinic establishment that changed Isaiah 7:14, Psalm 40:6, Deuteronomy 32:8, Deuteronomy 32:43, Amos 9:11–12, and dozens of other Messianic texts (see Chapters 7–10, 14–15 for detailed analysis) also changed the numbers in Genesis 5 and 11.

The motivation was the same in both cases: to undermine the Christian interpretation of the Old Testament. The rabbis altered the prophecies to weaken the case that Jesus fulfilled them. They altered the chronology to undermine the Christian argument that Jesus came at exactly the right time in world history — at the beginning of the sixth millennium, in the "fullness of time," at the end of Daniel's seventy weeks.

These were not separate acts of tampering. They were part of a coordinated effort — driven by the same leaders (Akiba and his circle), occurring in the same time period (the early-to-mid second century AD), and motivated by the same theological agenda (discrediting Christianity and promoting the rabbinic alternative). The Seder Olam, the proto-Masoretic text, and the replacement translations of Aquila, Symmachus, and Theodotion (see Chapter 13) were all tools in this same campaign.⁴⁷

As the church fathers themselves recognized, this was a pattern. Justin Martyr, writing in the mid-second century, accused the rabbis of deliberately altering their Scriptures to discredit Christ (see Dialogue with Trypho 71). Augustine wrote that "the Jews, envying us for our translation of their Law and Prophets, have made alterations in their texts to undermine the authority of ours" (City of God 15.11). The chronological changes and the prophetic changes were part of the same phenomenon — and the early church knew it.⁴⁸

Addressing the Main Counterargument: Did the LXX Inflate the Numbers?

I want to be fair here. Not everyone agrees with the position I've been arguing. The main counterargument — advanced by various evangelical scholars who defend the MT — is that the LXX inflated the numbers rather than the MT deflating them. According to this view, the Alexandrian translators of the Septuagint added 100 years to each patriarch's begetting age to push the chronology further back into the past.

Why would the Alexandrian Jews do this? The most common suggestion is chronological envy. Egypt had an ancient and venerable history. The pyramids were already two thousand years old when the LXX was translated. Perhaps the Jewish translators wanted to make their own history look more ancient and impressive by inflating the numbers.

I take this argument seriously, and I want to present it fairly. But I believe it fails for several reasons.

First, the "envy" argument has significant problems of its own. The Jewish community in Alexandria was proud of its heritage, but there is no evidence that they felt chronological inferiority to Egypt. The Alexandrian Jews already had a rich theological identity rooted in their covenant relationship with God — something no Egyptian chronology could compete with. Moreover, the idea that Jewish scholars would alter their sacred Scriptures to keep up with Egyptian chronological claims gives far too little credit to the reverence with which ancient Jews treated their holy texts. This is the Torah we're talking about — the most sacred document in all of Judaism. The suggestion that scribes would casually inflate its numbers to compete with pagan chronologies is deeply implausible.

Second, as we already discussed, the Nahor problem is devastating for the inflation theory. If someone were adding 100 years to each patriarch's age, there would be no reason to add only 50 years to Nahor. But if someone were subtracting 100 years, the editors would have had to stop at 50 for Nahor to avoid a mathematical absurdity. The exception falls exactly where deflation predicts it should, and exactly where inflation cannot explain it.⁴⁹

Second, the inflation theory requires a conspiracy among the LXX translators — a coordinated agreement to systematically alter the numbers. But the LXX was a translation project, not a scribal revision. Different translators worked on different books. There is no plausible mechanism by which a coordinated numerical inflation could have been carried out during a translation project. By contrast, the deflation theory requires only a single editorial authority — the rabbinic establishment, which controlled the text after the destruction of the Temple — to make the changes. As Smith has pointed out, "a defense of the MT also requires an explanation of how the leaders in Alexandria would have been able to maintain control over the falsely inflated numbers in LXX manuscripts once the copies left the Alexandrian library."⁵⁰

Third, Josephus provides first-century testimony that the longer chronology was the accepted Hebrew chronology. Josephus did not use the LXX — he explicitly says he translated from the Hebrew. If the Hebrew text available to Josephus had the shorter (MT) numbers, he would have used them. The fact that he used the longer numbers proves that the Hebrew text he had access to preserved the longer chronology.⁵¹

Fourth, the text-critical principle of lectio brevior ("the shorter reading is more likely original") is sometimes cited in support of the MT. But this principle applies to accidental scribal omissions — cases where a copyist's eye skipped a line or dropped a word. It does not apply to systematic numerical alteration. The consistent subtraction of exactly 100 years from every patriarch is not an accidental omission — it is a deliberate change, and lectio brevior is irrelevant to deliberate changes.⁵²

Fifth, Augustine's testimony is worth noting. While Augustine in one passage suggested a "rogue scribe" might have inflated the LXX numbers, he contradicts himself elsewhere by explicitly using the LXX's chronological numbers — including the LXX's total of approximately 1,072 years from the Flood to Abraham — as authoritative. As Smith observes, Augustine's "embrace of the LXX's numbers in Gen 11 as representing the original, inspired text is irrefutable." Augustine also accepted Cainan. Whatever he may have speculated about a rogue scribe, his actual practice was to follow the LXX chronology.⁵³

Conclusion: The Missing Centuries Are Real

Let me draw the threads together.

The postdiluvian chronology of Genesis 11, like the antediluvian chronology of Genesis 5, shows unmistakable evidence of deliberate deflation in the Masoretic Text. The mathematical precision of the changes — exactly 100 years subtracted from patriarch after patriarch, with a reduced subtraction for Nahor (where 100 years would create an impossibility), and the omission of an entire generation (Cainan, confirmed by Luke's Gospel) — rules out accidental scribal error and points to intentional editorial revision.

The consequences of this compression are severe. The MT's timeline creates historical absurdities — Shem outliving Abraham, impossibly compressed time for the rise of civilizations, insufficient time for the Tower of Babel, the Table of Nations, and the archaeological record of early human history. The LXX's longer chronology avoids all these problems.

The independent witnesses — Josephus, the Liber Antiquitatum Biblicarum, the Samaritan Pentateuch (partially), the church fathers, and Luke's Gospel — all confirm the longer chronology. The Seder Olam provides the historical mechanism by which the compression was carried out, and the manipulation of Daniel's seventy weeks provides the theological motive.

As we have argued throughout Part III of this book, the corruption of the Masoretic Text was not limited to individual verses or isolated passages. It was a comprehensive program of textual revision — affecting Messianic prophecies, chronological data, and the canonical boundaries of Scripture itself. The Genesis 5 and 11 chronologies are among the most dramatic examples of this revision, and the evidence for deliberate MT deflation is, in my judgment, overwhelming.

The missing centuries are real. And it's time for the church to recover them.

For too long, Protestant Christians have built their understanding of biblical chronology on the foundation of the Masoretic Text — a text whose chronological data was altered by second-century rabbis who rejected Jesus as the Messiah. We have accepted Bishop Ussher's date of 4004 BC for Creation as if it were gospel truth, without asking whether the Hebrew text Ussher relied on was itself reliable. We have adopted William Henry Green's "gaps" theory as a convenient way to avoid the archaeological problems created by the MT's compressed timeline, without asking whether the compressed timeline was itself the problem.

The evidence presented in this chapter — and in the preceding chapter on Genesis 5 — points overwhelmingly to a single conclusion: the LXX preserves the original, inspired chronology, and the MT's numbers have been deliberately altered. The mathematical precision of the alterations, the testimony of Josephus and the Liber Antiquitatum Biblicarum, the partial agreement of the Samaritan Pentateuch, the universal practice of the church fathers, the confirmation of Luke's Gospel regarding Cainan, the Nahor "smoking gun," and the historical absurdities created by the MT's compressed timeline — all of these converge on the same conclusion.

I know this is a challenging conclusion for many Protestant readers. It means that the Old Testament text we've been reading — the Hebrew text behind our English translations — has been tampered with in ways that affect not just individual verses but the entire timeline of world history. That's an uncomfortable realization. But the evidence demands that we follow it where it leads, even when the destination is unexpected. The Bible is true — but the version of the Bible's chronology that most Protestants have inherited is not the original. The original is preserved in the Septuagint. And the sooner we recognize that, the better equipped we will be to defend the historical reliability of Scripture against its critics.

In the next chapter, we'll turn to the broader question of the Masoretic Text's late standardization and what it means for the authority that Christians should — or should not — grant to the MT as a whole.
