The Rabbinic Deflation Hypothesis

If one compares the chronologies of Genesis 5 and 11 as they appear in the Masoretic Text (MT) – which is what most of our bibles use for these dates – with those in the Septuagint (LXX), one finds roughly a 1500 year discrepancy.

The LXX (or Alexandrian) Inflation Hypothesis explains this discrepancy by saying that the Greek translators of the lost Hebrew text of Genesis of their time (called the Vorlage) inflated the dates in the 3rd century BC to better agree with Egyptian history. The Rabbinic Deflation Hypothesis explains this discrepancy by saying that the rabbis in the 2nd century AD deflated the numbers to discredit Jesus as the Messiah.

In the following interview Henry B. Smith Jr of the Associates for Biblical Research (ABR) argues for the Rabbinic Deflation Hypothesis. It is long, so I have commented on it section by section with links to each part.

The correct dates are important for both archeology and apologetics.

The Christian archeologist has to know what the original Genesis text said about the events following the flood. Apologists who accept the Bible as an historical document also need to be clear about what that history actually is. Attacks against any Christianity that has not been watered down to a new age belief system come from those who want to discredit the Bible as reliable history.

  1. 0:00 Michael Filipek’s introduction
  2. 6:20 Henry B. Smith Jr’s introduction. He notes that there are no chronological gaps in these genealogies. He also asserts that the biblical text has higher authority over external evidence.
  3. 16:05 There are three textual traditions with differences in the genealogies: the MT, the LXX, and the Samaritan Pentateuch (SP). The correct dates are needed for archeological research and for apologetics. Smith Jr focuses on Genesis 11 because these dates come after the flood where archeological evidence has to be located and there the internal evidence is greatest for the Rabbinic Deflation Hypothesis.
  4. 25:02 Smith Jr contrasts the total number of years in these chronologies. For the MT it is 2008 years. For the SP it is 2249 years. For the LXX it is 3394 years. Although creation science explores the entire chronology beginning with creation, archeologists would only have evidence for the time after the flood.
  5. 33:15 Smith Jr analyzes the dates for Peleg as an example.
  6. 35:00 Smith Jr analyzes the dates for Kainan as another example. Kainan is mentioned in Luke 3:36 and the LXX, but not in the MT nor the SP.
  7. 40:37 Smith Jr offers a warning about critical scholarship: although there might be treasures hidden there many of these scholars support the Documentary Hypothesis which entirely discredits the historical value of these chronologies. He also comments that preservation of Scripture does not require that it be preserved in Hebrew manuscripts. It could be preserved in other languages, such as, Greek.
  8. 44:51 Whoever made the deliberate changes to the text would need a high enough motivation to overcome the command in Deuteronomy 4:2 not to change the text. They would also need the means to disseminate the changes and the opportunity to do so.
  9. 54:30 There are external witnesses before the second century AD to the LXX reading of Genesis 5 and 11: Liber Antiquitatum Biblicarum (LAB), Josephus, Eupolemus, and Demetrius of Alexandria as early as 220 BC. However, there are no external witnesses before the second century AD to the MT reading.
  10. 1:24:00 Smith Jr returns to Peleg as an example of a methodology on how to approach these texts.
  11. 1:28:54 Smith Jr points out the internal evidence in the MT that there is not enough time from the flood to the Babel dispersion for the population to reach the state that Genesis 10 describes it to be in. He notes that some people may find it hard to believe that the rabbis would have deflated their own texts and some may also have a long-term commitment to Ussher’s chronology which is based on the MT.
  12. 1:43:45 Smith Jr introduces the Rabbinic Deflation Hypothesis. Chrono-messianism used 1000-year blocks and the Daniel 9 prophecies to predict the coming of the Messiah. The Seder ‘Olam Rabbah became a new chronology in the second century AD. The rabbis wanted to put Jesus outside of biblical prophecies.
  13. 1:59:21 Ancient support for the Rabbinic Deflation Hypothesis comes from Eusebius, Julian of Toledo, Jacob of Edessa and Bar Hebraeus.

The following diagram compares the ABR chronology1 which prefers the LXX dates because it accepts the Rabbinic Deflation Hypothesis with James Ussher’s chronology2 which prefers the MT because it accepts the LXX Inflation Hypothesis.

Old Testament Chronology and the Age of Mankind

Douglas Petrovich presented a framework for building a sound chronology of the Old Testament at the 2023 Chafers Theological Seminary Pastors’ Conference. If one chooses appropriate assumptions one can come up with a chronology that is faithful to the Bible and also synchronizes with Egyptian and Assyrian chronologies. This confirms the reliability of the biblical record as history.

To build this chronology one needs certain dates that one has confidence in to serve as “tent pegs” as Petrovich calls them. Reaching consensus on what those tent pegs are is not easy but it is achievable. Having that chronology allows one to date and make sense out of the archeological data. That we need to go through so much trouble to construct such a chronology is reason to believe that mankind is very young.

Construction Begins on the First Temple—967 BC

I Kings 6:1
And it came to pass in the four hundred and eightieth year after the children of Israel were come out of the land of Egypt, in the fourth year of Solomon’s reign over Israel, in the month Zif, which is the second month, that he began to build the house of the Lord.

Can we find what year Solomon began to build the first temple in our calendar? James Ussher in his Annals of the World gave the date as 1012 BC. Edwin Thiele was able to establish an absolute date based on Assyrian records linked to a solar eclipse which occurred in June 15, 763, in The Mysterious Numbers of the Hebrew Kings. This allows one to come up with 967 BC as the year Solomon initiated the building of the first temple. There is a discrepancy of 45 years between these dates. Rodger Young clarified the issues around this discrepancy in Ussher Explained and Corrected arguing in favor of the 967 BC date which Petrovich accepts.

Israelite Exodus from Egypt—1446 BC

Accepting 967 BC and the information in 1 Kings 6:1 about the Exodus occurring in the 480th year one can date the Exodus back to 1446 BC (967+479=1446). From this date and knowing the Israelites wandered for 40 years in the desert (Numbers 32:13) we get the year they crossed the Jordan into Canaan as 1406 BC (1406+40=1446).

Jacob Moves His Family to Egypt—1876 BC

If one concludes as Petrovich does (see his Origins of the Hebrews, 2021) that the Israelites spent 430 years in Egypt, the “long sojourn”, rather than 215 years, the “short sojourn”, then the date the long sojourn began would be 1876 BC. It becomes another tent peg (1446+430=1876). The date the short sojourn began would be 1661 BC (1446+215=1661).

The reason for the 215 year discrepancy is due to textual variants of Exodus 12:40. The Masoretic Hebrew text gives 430 years in Egypt. The Septuagint Greek text said this period of time included time in Canaan.

This lecture highlights the resolution of difficulties permitting one to construct a sound Old Testament chronology. At 19:25 in the video Petrovich lists the major dates going back to Abraham. At 55:15 he presents the Egyptian chronological scheme.

He recommended the following sources for those interested in pursuing biblical chronology further:

Why Mankind Is Very Young

William Lane Craig, the professor of philosophy at Houston Baptist University and research professor of philosophy at Talbot School of Theology, asserts, “Adam plausibly lived sometime between around 1 million years ago to 750,000 years ago, a conclusion consistent with the evidence of population genetics.” (The Historical Adam, First Things, October 2021).

Much of the Old Testament chronology presented above goes back less than 4000 years. However, it involves controversy as to when something actually happened. This should make anyone pause who claims that humanity has been on this earth for much longer than 8000 years. Why? Because there is no historical evidence to justify that claim. Furthermore Biblical textual variants do not even justify ages as old as 8000 years.

From available historical evidence we know we can go from stone age to space age in about 5000 years. That means if humanity were around for 100,000 years (let alone the million that Craig finds plausible) we would have historical records going back 90,000 years assuming a generous 10,000 years to go from stone age to space age.

If we had such historical records then there would be no doubt about what happened a mere 4000 years ago. We would have archived video recordings of Solomon holding a press conference broadcasted live to the entire world via satellite in 967 BC about the construction of the temple. We would know precisely when that press conference started. Constructing a sound biblical chronology would not be the problem that it is today.

Since we don’t have that kind of historical record it is reasonable to doubt the non-historical dating methods and speculations that extend mankind back hundreds of thousands of years. Mankind is nowhere near that old.
