Leviticus 20:3-6

3I myself will set my face against him and will cut him off from his people; for by sacrificing his children to Molek, he has defiled my sanctuary and profaned my holy name. 4If the members of the community close their eyes when that man sacrifices one of his children to Molek and if they fail to put him to death, 5I myself will set my face against him and his family and will cut them off from their people together with all who follow him in prostituting themselves to Molek. 6“ ‘I will set my face against anyone who turns to mediums and spiritists to prostitute themselves by following them, and I will cut them off from their people.
