Deuteronomy 23:17-18 - Cult Prostitution Forbidden
17 No daughter of Israel is to let herself be used as a loose woman for a strange god, and no son of Israel is to give himself to a man. 18 Do not take into the house of the Lord your God, as an offering for an oath, the price of a loose woman or the money given to one used for sex purposes in the worship of the gods: for these two things are disgusting to the Lord your God.
