I am on my way out for an extended vacation as we speak for the holiday.
No offense was intended.
I am a retired teacher of the Bible, though an exJW who left the religion a very long time ago and decided to become an educated teacher in linguistics, Catholic and Jewish liturgy, etymology and manuscript transmission. I was also a catechist for some years, though I worked mainly for Protestant churches and academies.
Right before I retired a few years ago, there was an update, at least in Judaism and Europe, on the document hypothesis, as to how the Bible was written. It was changed due to archeology and Jewish history. This is what I based my comments on.
While I have little time to go into detail since I have to leave in just a bit (perhaps you can do the research since that is what you apparently do if you are an academic and I am now retired), the theory works like so:
- The Jews did not descend from a person called "Abraham" but are likely the Cananites themselves.
- There were no 12 Tribes; this is folklore and mythology.
- Israel was a separate tribe from Judea that when it was conquered absorbed some of its remaining refugees and folklore.
- There was never a "Golden Age of Solomon."
- After the Exile, a small writing we call "Deuteronomy" was expanded into the Torah
- The writers were favoring the Judeans
- The Torah is actually composed of the books of Genesis through 2 Chronicles, created around the book of Deuteronomy by the "Judean" Redactor(s)
None of the material in these books is historical; it is political-religio-mythology designed to invent a new society after the return from Babylonian exile under the control of the Levitical priesthood
The Levites did not expect the world power of Greece to conquer the Persians. This altered their plans. When they attempted to change it by creating the Hasmonean dynasty, the effect backfired due to the fact that members of their own tribe, Levites, were anointed as king instead of members of the tribe of Judah. When they made a pact with the Herods who had secretly made a pact with Rome, they lost control and they inadvertently created the "Messianic doctrine" that would develop into Christianity and the Bar Kokhba Revolt of 136 A.D.
The "prologue" to the Torah (Genesis 1-2:3) is now attributed to what they call R of this Judean/Levitical authorship. It is based on the theology of a "punishing God" that was abandoned after 1) the Shoah and 2) with the introduction of such thinkers like Rabbi Modecai Kaplan who taught that God was not personal or a supernatural entity in the footsteps of Moses Maimonides and Benedict de Spinoza.
