Was there a devil in mithra and Zoroastrian lore?
MODERN Judaism has no devil. Satan is alive and well within the Old Testament. He’s obviously not a good guy. Satan means “resister,” and he’s always up to no good in the Scriptures. The earliest extra-biblical accounts of Jewish beliefs were written hundred of years after the Hebrew Bible was completed. Don’t think that what Jews believe today or then are the same as what Moses or King David believed.
