The concept of heaven and hell with the multiple levels is perhaps the strongest clue.
Hindu texts had concepts, that later were prominent in apocalyptic Judaism and Christianity, that were in the oldest Hindu texts from the start.
Consider the Yama Yima issue and the Hellhound.
Consider the multiple levels of hell
Consider the multiple heavens.
Historians say that the hellhound was a common Indo European concept, but I think the Hindus had it first then ( perhaps through the Hurrians ) took it to Greece.
Regardless, the concept ( from multiple points of entry ) made it into Judaism and especially the Book of Enoch.
Greek concepts (from India, Iran, Hurrians, etc. originally ), Iranian concepts, direct Hindu concepts made their way into 2nd Temple Judaism.
I don't see the initial Israelite beliefs having many later features such as the multiple heavens and multiple levels of hell. Infact not much evidence of the concept in a singular stage.
(just to clarify, the hellhound isn't in biblical beliefs, but the hound went to Greece along with all the other features of hell, plus hell itself, which the oldest Hindu texts have )
