Leviticus 20:25-27

New Revised Standard Version, Anglicised

²⁵ You shall therefore make a distinction between the clean animal and the unclean, and between the unclean bird and the clean; you shall not bring abomination on yourselves by animal or by bird or by anything with which the ground teems, which I have set apart for you to hold unclean. ²⁶ You shall be holy to me; for I the Lord am holy, and I have separated you from the other peoples to be mine.

²⁷ A man or a woman who is a medium or a wizard shall be put to death; they shall be stoned to death, their blood is upon them.
