Leviticus 20:22-27 - You Shall Be Holy
22 " 'And you shall keep all my statutes and all my regulations, and you shall do them, so that the land, to which I am bringing you to inhabit it, shall not vomit you out. 23 And you shall not follow the statutes of the nation that I am driving out {from before you}, because they did all these things, and I detested them. 24 So I said to you, "You yourselves shall take possession of their land, and I myself shall give it to you to possess it--a land flowing with milk and honey"; I [am] Yahweh your God, who {has set you apart} from the nations. 25 And you shall distinguish between the clean and the unclean animal and between the unclean and the clean bird; and you shall not defile yourselves with the animal or with the bird or with anything that moves along the ground that I have set apart for you {as unclean}. 26 And you shall be holy for me, because I, Yahweh, [am] holy, and I have singled you out from the nations to be mine.
27 " 'And a man or a woman, if a spirit of the dead or a spirit of divination is in them, they shall surely be put to death; they shall stone them with stones--their blood [is] on them.'"
