Yes Heaven was mentioned as a place where God dwells. It was not yet the Persian version.
I literally cannot believe you expect the Jewish scripture to actually mention another religion they are taking ideas from??????
What happens is a Jewish "prophet" one day says "I'm getting a communication from God, I must go pray......." then he comes back and says "Yahweh said we too are getting a savior, ours will be the true savior....."
And so on. It's all B.S,. But they don't CREDIT other religions??
Does Noahs ark credit the Epic of Gilamesh? NO?!
Does the creation narrative credit the Mesopotamian myths it closely follows? NO!?!?!
David mentioned dwelling in heaven with God in the Psalms, and this was before the Persian invasion. Psalm 23:6
Surely goodness and mercy shall follow me all the days of my life: and I will dwell in the house of the LORD for ever.
Are you saying that if you didn't believe Noah's Ark and the creation narrative were taken from the Epic of Gilgamesh and Mesopotamian myths you wouldn't think that Christian sources not mentioning Zoroastrianism is proof they aren't borrowed from them? Some Christians think Adam and Eve could have details that are allegories.
