Leviticus 20:3; Leviticus 20:5

3 I myself will set my face against that man and will cut him off from among his people, because he has given one of his children to Molech, to make my sanctuary unclean and to profane my holy name.

5 then I will set my face against that man and against his clan and will cut them off from among their people, him and all who follow him in whoring after Molech.
