Deuteronomy 23:15

12 Thou shalt have a place also without the camp, whither thou shalt go forth abroad:

13 and thou shalt have a paddle among thy weapons; and it shall be, when thou sittest down abroad, thou shalt dig therewith, and shalt turn back and cover that which cometh from thee:

14 for Jehovah thy God walketh in the midst of thy camp, to deliver thee, and to give up thine enemies before thee; therefore shall thy camp be holy, that he may not see an unclean thing in thee, and turn away from thee.

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

16 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.

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

18 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.
