Thanks for the encouragement. Yes I’m very familiar with the Documentary Hypothesis, as well as the history of its rise, fall, and subsequent reprise. In my missspent youth I spent a lot of time arguing against it. Then I studied the Bible more carefully and realized there was truth in it. Then I started reading better scholarly literature and gradually caught up with the current state of play. It was quite revealing.
I am very much in agreement that the Deuteronmic code follows the second millennium BCE suzerainty treaties; Kenneth Kitchen has written on this matter with great skill (since he is tremendously qualified). And yes we must pause when dating the Pentateuch. But I’m only speaking of Genesis 1-11.
Naturally I have sympathy for this point of view, since my personal view is the “day/vision” interpretation.
Most of the Pentateuch undobutedly pre-dates the Exile. But the Pentateuch shows evidence of extensive editing and redaction over the years, and Genesis 1-11 certainly dates to the Exile at earliest. There’s a very obvious literary seam between Genesis 11 and Genesis 12. It is pretty well established across the board that Genesis 1-11 is a literary unit post-dating the rest of the Pentatuech. I have written on this topic before, and nothing I have written is remotely new, it’s all very well recognized in the literature.
