Leviticus 20:5-8

⁵then I will set my face against that man, and against his family, and will cut him off, and all that go a whoring after him, to commit whoredom with Molech, from among their people.

⁶— And the soul that turneth unto necromancers and unto soothsayers, to go a whoring after them, I will set my face against that soul, and will cut him off from among his people.

⁷Hallow yourselves therefore, and be holy; for I am Jehovah your God.

⁸And ye shall observe my statutes, and do them: I am Jehovah who hallow you.
