Leviticus 20:3-7

And I will set my face against that man, and will cut him off from among his people; because he hath given of his seed unto Molech, to defile my sanctuary, and to profane my holy name.

And if the people of the land do any ways hide their eyes from the man, when he giveth of his seed unto Molech, and kill him not:

Then 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.

And the soul that turneth after such as have familiar spirits, and after wizards, to go a whoring after them, I will even set my face against that soul, and will cut him off from among his people.

Sanctify yourselves therefore, and be ye holy: for I am the LORD your God.
