Augustine of Hippo : There will be no prostitute among the daughters of Israel and there will be no man prostituted among the children of Israel. This is the text in which it is expressly prohibited to fornicate, not only men, but women, even with their own spouses, demonstrating that it is a sin to mix with people other than the spouses themselves, since it is prohibited to have prostitutes and approach those whose sexuality is publicly sold. In the Decalogue it seems that this was not explicitly prohibited under the name of moechia, because under this name only adultery is usually understood. Therefore, I have already stated in that passage what I thought about this topic. — QUESTIONS ON DEUTERONOMY, Q. 37 (tr. J. Litteral, draft)
