I was trolling the internet and I managed to find this nifty resource on the Book of Genesis. Scroll past all the links and you get to a break down of the book, with tentative ascriptions to sources. Here’s how it breaks Genesis down:
- Primitive History (1-11)
- Abraham’s narrative (12:1-25:18)
- Isaac and Jacob’s narrative (25:19-36:43)
- Joseph’s narrative (37:1-50:26)
It’s a good way of thinking of the Book, and it certainly helps to see it all laid out like that. Check out the site for a more detailed breakdown.
