Deuteronomy 23:17 - 23:18
17 “None of the daughters of Israel shall be a cult prostitute, nor shall any of the sons of Israel be a cult prostitute. 18 You shall not bring the hire of a harlot or the wages of a dog into the house of Yahweh your God for any votive offering, for both of these are an abomination to Yahweh your God.
