Leviticus 20:5-8

⁵Then will I set my face against that man, and against his family, and I will cut him off, and all that go astray after him, to go astray after Molech, from among their people.

⁶And the person that turneth unto such as have familiar spirits, and unto wizards, to go astray after them,—then will I set my face against that person, and will cut him off from among his people.

⁷Sanctify yourselves therefore, and be ye holy; for I am the Lord your God.

⁸And ye shall keep my statutes, and do them: I am the Lord who sanctify you.
