I would be curious to see if they were comparing popular teachings about Hell or Biblical text on Hell, to these other religions.
Someone on this sight put out the challenge that the same was true about the teachings on Satan. It did not take much time, in reading the book he quoted from, to see that the author was not arguing against the Biblical text, but popular teachings.
Or you may try reading something like: “The Birth of Satan: Tracing the Devil's Biblical Roots” – by T. J. Wray. This includes Mesopotamian, Canaanite, and Egyptian influences on Satan as well as the Persian; and it is online.
I've been reading it. This guy does not seem to know much about the Bible. He compares Satan to other evil gods. Satan is an angel, not a god. He says Satan, like these others, rules the underworld. No he doesn't. The "underworld" will one day be his prison, but he is not there now. He compares the depiction of having horns and a tail. Satan doesn't have these. Wray compares Enki, "artfully adept at circumventing the divine will," with Satan. Satan can only follow the will of God. He can not act without God allowing it. Wray does not even seem to know that there is a difference between
Sheol and
Gehenna.
Sheol (Old Testament) is the equivalent of
Hades in the New Testament. This is the holding cell for the dead. It used to have two compartments, one for the righteous and one for the unrighteous (see Luke 16:20-26). Now that Jesus has paid our dept, the righteous go straight to Heaven.
Gehenna is the same as The Lake of Fire. Both of these names are from the New Testament. The Old Test. name for
Gehenna was
Tophet (Isaiah 30:33). If fact both words refer to the Valley of Hinnom.
Hades/Sheol will be cast into The Lake of Fire/
Gehenna (Revelation 20:13-15).
Sheol/Hades is just the county jail. After sentencing you go to the federal penitentiary. Both are bad but one is worse.
He makes a lot of his comparisons between these other ancient stories and popular myths about Satan. He apparently can not find what he needs in the Bible. Another thing is that the Bible does not teach dualism, Satan is a created being and not equal to God.
In fact, I can wrap up Wray's evidence like this, "there is a possibility that these other stories could have influenced the Biblical descriptions of Satan, so let us just assume they did." He has no proof and in fact his examples show the opposite. They show that it is unlikely the Jews barrowed these ideas.
