Leviticus 20:22-27 - You Shall Be Holy
22 Ye shall therefore keep all my statutes, and all my judgments, and do them: that the land whither I bring you to dwell therein, may not vomit you out. 23 And ye shall not walk in the manners of the nations which I cast out before you: for they committed all these things, and therefore I abhorred them. 24 But I have said to you, Ye shall inherit their land, and I will give it to you to possess it, a land that floweth with milk and honey: I am the LORD your God, who have separated you from other people. 25 Ye shall therefore distinguish between clean beasts and unclean, and between unclean fowls and clean: and ye shall not make your souls abominable by beast or by fowl, or by any manner of living animal that creepeth on the ground, which I have separated from you as unclean. 26 And ye shall be holy to me: for I the LORD am holy, and have severed you from other people, that ye should be mine.
27 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.
