Leviticus 20:5-7

American Standard Version

⁵ then I will set my face against that man, and against his family, and will cut him off, and all that play the harlot after him, to play the harlot with Molech, from among their people.

⁶ And the soul that turneth unto them that have familiar spirits, and unto the wizards, to play the harlot after them, I will even set my face against that soul, and will cut him off from among his people. ⁷ Sanctify yourselves therefore, and be ye holy; for I am Jehovah your God.
