Leviticus 20:3-5

3I also 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.

4And if the people of the land do any ways hide their eyes from that man, when he giveth of his seed unto Molech, and put him not to death:

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.
