Perhaps so, but if so, God has been speaking so vaguely as to allow people to hear his “voice” as advocating Buddhist atheism, Hindu belief in the caste system, Zoroaster’s dualistic view, animism, human sacrifice, temple prostitution… Some Jews apparently “learned” human sacrifice and temple prostitution from the Assyrians or others, not unlike their learning monotheism from Persians, as you suggest… the Assyrians and others who themselves had presumably developed those ideas of course by God speaking to ALL people.
And thus it is possible that the ideas of the Hindus were building blocks to guide the Buddhists to seek belief in reincarnation, the ideas of the Assyrians were building blocks to guide the Hebrews to temple prostitution and child sacrifice…
it should be observed that they showed up looking for “the king of the Jews”, so one might have a sense who was being primarily influenced by whom?
But if I may, my most significant question to you is…
and have God confirm them how, exactly?
