I mean (many of) the earliest Bibles were in Coptic (which is still used liturgically by some of the oldest Orthodox churches). Christianity also really inherited that form of dualism more from the Zoroastrians so Avestan is another great option. But if you want to come from the Judaic roots yeah babylon was the origin of the major opposing deities in Judaism's early monolatrist perspective so especially if you're fighting the Abrahamic God with Baal that would be your main pick.

Side Rant: It really cannot be overstated how much the Catholic church really fucked up Christianity. It was originally a syncretistic anti imperialist death cult (in that you would martyr yourself by publicly accepting death over imperialism). If I ever got a time machine Athanasius of Alexandria is much higher on my list than Hitler. It's not even that I'm specifically opposed to trinitarianism—the number three does seem significant to some universal truth across numerous cultures (Plato's chariot, Taoist three elements of destiny, even Freud to name a few)—but killing people en masse over it is unspeakable. And to have subsequent traditions who were supposedly otherwise anti-catholic in any other respect still specifically follow in the tradition of murder for some reason is ridiculous.
