Leviticus 20:26-27

American Standard Version

²⁶ And ye shall be holy unto me: for I, Jehovah, am holy, and have set you apart from the peoples, that ye should be mine.

²⁷ A 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.
