Leviticus 20:22-27 - You Shall Be Holy
22 "'See that ye keep therefore all mine ordinances and all my judgments, and that ye do them: that the land, whither I bring you to dwell therein, spew you not out. 23 And see that ye walk not in the manners of the nations which I cast out before you: For they committed all these things, and I abhorred them. 24 But I have said unto you that ye shall enjoy their land, and that I will give it unto you to possess it: even a land that floweth with milk and honey. I am the LORD your God, which have separated you from other nations: 25 that ye should put difference between clean beasts and unclean, and between unclean fowls and them that are clean. Make not your souls therefore abominable with beasts and fowls, and with all manner thing that creepeth upon the ground, which I have separated unto you to hold them unclean. 26 Be holy unto me, for I the LORD am holy and have severed you from other nations: that ye should be mine.
27 "'If there be man or woman that worketh with a spirit or a maker of dismal days, they shall die for it. Men shall stone them with stones, and their blood shall be upon them.'"
