 Several of these scholars, such as Professor Martin Rose and John Bright, suggest that during the First Temple period the people of Israel believed that each nation had its own god, but that their god was superior to other gods.Some suggest that strict monotheism developed during the Babylonian Exile, perhaps in reaction to Zoroastrian dualism.In this view, it was only by the Hellenic period that most Jews came to believe that their god was the only god and that the notion of a clearly bounded Jewish nation identical with the Jewish religion formed.
