I was watching a debate where a Mormon claimed to a Christian that early Jews believed that other gods existed besides YHWH, but they only had a covenant with a single god (YHWH). He never got a chance to share his references. I suppose he could be referring to Talmud or something but I am not familiar with any Jewish writings outside of the Bible.
Does anyone know of any early Jewish writings that would either confirm his statement or at least explain where he might have gotten that idea from?
The words henotheism or monolatry have been used to describe this belief.
I can see how something like "Thou shalt have no other gods before Me" could be referencing gods which actually existed or it could be simply referring to non-existent "gods" that people claimed were real and would worship.
So I guess the question might also come down to, how did early/ancient Jews interpret that? It's possible to believe other gods exist without worshiping them because you believe your god is more powerful.
I'm more concerned with Moses onward as much about God was clarified in the Torah and Mosaic teachings.
Any Talmudic or other references to support would be really cool thanks!
