VERY few people seem to realize that there are actually two separate flood accounts recorded within the Genesis timeline, and I can’t blame them. The mention is so brief in Yashar that it managed to slip right on by me through several consecutive reads. Well, here it is.
5 And every man made his elohiym and they bowed down to them, and the sons of men forsook Yahuah all the days of Enosh and his children; and the anger of Yahuah was kindled on account of their works and abominations which they did in the earth. 6 And Yahuah caused the waters of the river Giychon to overwhelm them, and he destroyed and consumed them, and he destroyed the third part of the earth, and notwithstanding this, the sons of men did not turn from their evil ways, and their hands were yet extended to do evil in the sight of Yahuah.
Yashar (Jubilees) 2:5-6 [Cepher]
The account happens very early on the timetable. Enosh was the grandson of A’dam and Havah through Sheth, and anyways, we’re only in the second chapter of Yashar. Noach’s flood doesn’t happen until chapter 6. Details seem slim, but we are given far more than most might appreciate. Firstly, the floodwaters originated with the Giychon. That’s one of the four rivers flowing from Eden. Secondly, the river was capable of flooding a third of the world, telling us there were many deaths but also a great deal of survivors. Though the anger of Yahuah was kindled on account of mankind’s rotten works as well as their abominations, the trigger point seems to be idolatry. That lines up with everything else I’ve read about the flood of Enosh. Yes, there is another account. You can read the full report in the PDF below. Enjoy.
