Leviticus 20:22-27 - You Shall Be Holy
22 "'You shall therefore keep all my statutes, and all my ordinances, and do them; that the land, where I am bringing you to dwell, may not vomit you out. 23 You shall not walk in the customs of the nation, which I am casting out before you: for they did all these things, and therefore I abhorred them. 24 But I have said to you, "You shall inherit their land, and I will give it to you to possess it, a land flowing with milk and honey." I am Yahweh your God, who has separated you from the peoples. 25 "'You shall therefore make a distinction between the clean animal and the unclean, and between the unclean fowl and the clean: and you shall not make yourselves abominable by animal, or by bird, or by anything with which the ground teems, which I have separated from you as unclean for you. 26 You shall be holy to me: for I, Yahweh, am holy, and have set you apart from the peoples, that you should be mine.
27 "'A man or a woman that is a medium, or is a wizard, shall surely be put to death: they shall stone them with stones; their blood shall be upon them.'"
