Deuteronomy 23:16-19

He may dwell with you in your midst, in the place which he chooses within one of your gates, where it seems best to him; you shall not oppress him. “There shall be no ritual harlot of the daughters of Israel, or a perverted one of the sons of Israel. You shall not bring the wages of a harlot or the price of a dog to the house of the LORD your God for any vowed offering, for both of these are an abomination to the LORD your God. “You shall not charge interest to your brother—interest on money or food or anything that is lent out at interest.
