When I was a teenager, I went to church, and almost every ‘Christian’ there was a complete asshole. What makes it worse is that they try to justify it. This honestly made me think that if God and Satan were real, I’d want to know Lucifer’s story. Maybe he’s not actually ‘evil.’
“can be” vs. “should be”. But yes, the god of the Torah is a jealous god. I mean, he flat-out says, “you shall have no other gods before me”. Not, “no other gods exist”, or “you can’t respect other gods”. Just, none before him. Which says that while he might be omniscient and omnipotent, he’s not the only god who is so.
Like, in the story he literally sends Moses’ follower to do a sorcery battle with the priests of the gods of Egypt. They’re both able to turn their staffs into serpents, which implies they’re both getting divine help. But Yahweh had the bigger serpent (could this be any more on the nose?), so was proven to be the more potent god.
This is interpreted both ways. The “original” Cult of Yahweh view saw the god Yahweh as El, the head god of the Canaanite pantheon. Later, after the Cult of Yahweh became old Judaism, the comandment was reinterpreted as Yahweh being the only god jews should worship, and then later as the only God, since any other divine being worshipped by others would not be God.
