In the podcast, the relevant story has to do with the period in the OT where ancient Israelites are going around killing people from the other nations. The explanation given in the podcast is that the gods of those people were very real. Even as far as that the people were half-god half-human; it's described 3-person sex rituals where there's one man, one woman, and a god who is possessing the man and the child is considered to have 2 fathers (the man and the god) and one mother.
So when the ancient Israelites were killing those other nations, it was to exterminate those other gods. And what happened was that the God of Abraham made a deal with all those gods, that a small number of them could stay and perform helpful chaotic actions which the God of Abraham permits, while the others were banished permanently. However, this stay would be temporary, and there was a time in the future when that small remnant would too become banished.
The above story is given as an explanation for why, in the NT (new testament in the Bible), some possessed people say to Jesus "Why have you come when it is not yet the time?" The spirit(s) who are possessing the man are referring to the pre-agreed upon time when the remainder of the gods will be banished from the Earth.
> And, behold, they cried out, saying, What have we to do with thee, Jesus, thou Son of God? art thou come hither to torment us before the time? (matthew 8:29, KJV)
I'm sure there's a billion reasons why this doesn't hold up to anything resembling scientific scrutiny, like, in any way. Still kinda badass imo.
