Maybe. There's no way to know for sure what's just anecdotal and what's a sin.

Yeah. Like I said. It's Jewish law. I know. It's the same thing with the gay passages.

That makes no sense. How would I not have read it if I know about it?

Well... Uh... It was actually really popular among Christians and there's still actually a lot of CSA incest in Christian housholds.

No. It's deadass a story. A man in commanded to marry his widowed sister and then commanded to impregnate her and then when he pulls out, he's punished. It's not a niche story. You should've read it yourself if you're an actual Christian.
