Deuteronomy 23:15-18

15Thou shalt not deliver unto his master a servant that is escaped from his master unto thee: 16he 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.

17There shall be no prostitute of the daughters of Israel, neither shall there be a sodomite of the sons of Israel. 18Thou 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.
