Leviticus 20:3-5

3I will also set My face against that man and will cut him off from among his people, because he has given some of his 1children to Molech, 2so as to defile My sanctuary and 3to profane My holy name. 4If the people of the land, however, 4should ever disregard that man when he gives any of his 5children to Molech, so as not to put him to death, 5then I Myself will set My face against that man and against his family, and I will cut off from among their people both him and all those who play the prostitute with him, by playing the prostitute with Molech.
