Leviticus 20:25-27

²⁵Ye shall therefore distinguish between clean beasts and unclean, and between unclean fowls and clean: and ye shall not make your souls abominable by beast or by fowl, or by any manner of living animal that creepeth on the ground, which I have separated from you as unclean.

²⁶And ye shall be holy to me: for I the LORD am holy, and have severed you from other people, that ye should be mine.

²⁷A man also or a woman that hath a familiar spirit, or that is a wizard, shall surely be put to death: they shall stone them with stones: their blood shall be upon them.
