Huayna Capac357
Deity
Well, according to a NOVA series, Egypt conquered a peoples in the land of Midian shortly after the Canaanite peoples started rebuilding their culture after their fall into barbarity.
These conquered people had a mountain/god called YHW. The theory is that some of the people escaped the Egyptians and migrated to the Canaanite lands. They then proselytized about their god, and tied it to their escape from the conquest. This might be where the Moses myth comes from, though there's no evidence of an Exodus of a large group of people who'd be enslaved generations earlier.
I can't rewatch those segments, 'cause they're not available to me. I've contacted a local professor of Judaism (as well as asking Plotinus). The professor said that the series was known to be quite accurate.
The cementing of monotheism appears to have happened after Solomon's purported time. That's obviously well after any Egyptian loss of its Canaanite vassals.
Very interesting. I wish Plotinus would give us some input on this.
