Leviticus 20:22-27 - You Shall Be Holy

²² “You are to keep all My statutes and all My ordinances, and do them, so that the land where I am bringing you to live will not vomit you out. ²³ You must not follow the statutes of the nations I am driving out before you, for they did all these things, and I abhorred them. ²⁴ And I promised you: You will inherit their land, since I will give it to you to possess, a land flowing with milk and honey. I am Yahweh your God who set you apart from the peoples. ²⁵ Therefore you must distinguish the clean animal from the unclean one, and the unclean bird from the clean one. Do not become contaminated by any land animal, bird, or whatever crawls on the ground; I have set these apart as unclean for you. ²⁶ You are to be holy to Me because I, Yahweh, am holy, and I have set you apart from the nations to be Mine.

²⁷ A man or a woman who is a medium or a spiritist must be put to death. They are to be stoned; their blood is on their own hands.”
