Deuteronomy 23:16-19

Let the slave live with you anywhere he likes, in any town he chooses. Do not mistreat him. No Israelite man or woman must ever become a temple prostitute. Do not bring a male or female prostitute’s pay to the Temple of the LORD your God to pay what you have promised to the LORD, because the LORD your God hates prostitution. If you loan your fellow Israelites money or food or anything else, don’t make them pay back more than you loaned them.
