Isn't Jehovah described as the God of Armies? You get the impression that he was part of a pantheon of gods at one point. And they weren't the only gods, since the ten plagues of Egypt indicates that Yahweh had challenged the Egyptian pantheon and --as one might expect in a work by his devoted followers-- he thrashed them soundly. The Egyptian gods were only able to duplicate some of Yahweh's miracles, and their attempt to replicate the turning of a rod into a snake was a humiliation when Aaron's rod-snake (heh) devoured the others.
I think a cool book would be the one where it is described how Yahweh struck down all of the other gods and took over as the one and only. Did he lock them in some alternate dimension? Did he steal their powers and trap them in the center of a star? Did he... =gulp= ...kill them?!?!?
There's an effects-laden HBO max-series just waiting to be filmed!
