Man!...wearing out my like button.
Definitely a (r)evolutionary time for the Hebrews.(OT).I think they found the boundaries of polytheistic belief,and opted for a more meaningful relationship(?).I can relate
.By boundaries I quote what Neer & Eye so eloquently posted elsewhere..."The gods were petty and cruel".But a God....a God that you exalt higher than all others,well that God would be more personable to you,and might would make you his "chosen".We see it again in the Romans conversion to christianity.(not all was by sword).
Too many gods...too many cooks to spoil the pot.And now the authors only had to speak for one God.Simple.Right?(hahaha..not hardly).
Starting in Genesis we see a major clash of styles.Most notably between the tales of the enuma elish,and the writings of the (P)riestly & the (E)lohim source.Not to mention the countless oral traditions that were in circulation at the time.Too many cooks do spoil the pot.The contradictions are apparent.As we see one author try to merge these gods into a 1+deity.Creator gods and destroyer gods all together now....almost.More like a polytheistic monarchy.With Yahweh getting promoted to head of the table.For some Hebrews.
And agreeing with Eye,I believe Abram was a big part of the refinement process.He initiated the age of henotheism,by taking Yahweh out of Ur?(if I remember right).Where Yahweh was amidst other sumerian and canaanite gods. So yeah.As you stated;Abram "revived" Yahweh.And in doing so,Yahweh led him to what would become the "holy land".A symbiosis of sorts.
I'm way off topic by now.Probably have been from the start.My ole lady says I shouldn't get stoned and discuss the bible.I ramble way off course.As I'm sure by now,you would agree.
Anyway..t'is the season.Hope it's a good one.
