Hey thx! I’m not seeing that porneia means ‘prostitution’ — its seems, in the LXX, to require the woman involved to be married, so the adultery violation is central. If a god is involved, then that’s the problem.
Irene E. Riegner’s The Vanishing Hebrew Harlot notes that prostitution wasn’t illegal or even wrong in ancient Israel, so it’s unclear why it’d be even a metaphor for the horror of porneia.
As a metaphor for non-Yahwist religious behavior, “prostitution” does not have the entailments, consequences, or the destructive social and legal implications that would generate enough revulsion to induce a switch to Yahwist praxis. This is especially true if prostitution is an acceptable institution to male Israelites.
