It's been a long day. As far as I am aware, the jealousy of God is that he doesn't want His children to belong to anyone else, only himself. My Hebrew is super-pathetic, but I have an interlinear and maybe that would be of some use for review. I have browsed the dead sea scrolls, and not all of it is cannon, yes, but certainly some of it is interesting. I'm not particularly interested in things outside the scope of cannon, excepting the apocryphal works. I have friends that swear by them, figuratively. Yes, gnostic heresy can be all over the place. I am putting Plato's "Republic" on my reading list right now, restocking my medicine bottle, then reading myself to sleep.
I am pretty sure the OT is referring to only one God, although I thought the similaraties between Baal and YWHW were pretty strange. I have never seen much to the contrary. There are some compound names, but they all refer to the Big Man as far as I am aware, because there has never been any distinction otherwise of note, not even any twisty hints I've been exposed to yet.
