Deuteronomy 23:16-19

he shall dwell with thee, in the midst of thee, in the place which he shall choose within one of thy gates, where it pleaseth him best: thou shalt not oppress him. There shall be no prostitute of the daughters of Israel, neither shall there be a sodomite of the sons of Israel. Thou shalt not bring the hire of a harlot, or the wages of a dog, into the house of Jehovah thy God for any vow: for even both these are an abomination unto Jehovah thy God. Thou shalt not lend upon interest to thy brother; interest of money, interest of victuals, interest of anything that is lent upon interest.
