Leviticus 20:22-27 - You Shall Be Holy
22 You shall therefore keep all my statutes, and all my judgments, and do them: that the land, where I bring you to dwell therein, vomit you not out. 23 And you shall not walk in the customs of the nation, which I cast out before you: for they committed all these things, and therefore I abhorred them. 24 But I have said unto you, you shall inherit their land, and I will give it unto you to possess it, a land that flows with milk and honey: I am the LORD your God, who has separated you from other people. 25 You shall therefore make a distinction between clean animals and unclean, and between unclean fowls and clean: and you shall not make your souls abominable by animal, or by fowl, or by any manner of living thing that creeps on the ground, which I have separated from you as unclean. 26 And you shall be holy unto me: for I the LORD am holy, and have separated you from other people, that you should be mine.
27 A man also or woman that is a medium, or that is a wizard, shall surely be put to death: they shall stone them with stones: their blood shall be upon them.
