Leviticus 20:22-27

Ye shall therefore keep all my statutes, and all mine ordinances, and do them; that the land, whither I bring you to dwell therein, vomit you not out. And ye shall not walk in the customs of the nation, which I cast out before you: for they did all these things, and therefore I abhorred them. But I have said unto you, Ye shall inherit their land, and I will give it unto you to possess it, a land flowing with milk and honey: I am Jehovah your God, who hath separated you from the peoples. Ye shall therefore make a distinction between the clean beast and the unclean, and between the unclean fowl and the clean: and ye shall not make your souls abominable by beast, or by bird, or by anything wherewith the ground teemeth, which I have separated from you as unclean. And ye shall be holy unto me: for I, Jehovah, am holy, and have set you apart from the peoples, that ye should be mine. A man also or a woman that hath a familiar spirit, or that is a wizard, shall surely be put to death: they shall stone them with stones; their blood shall be upon them.
