Leviticus 20:2-3

“Again, you shall say to the children of Israel: ‘Whoever of the children of Israel, or of the strangers who dwell in Israel, who gives any of his descendants to Molech, he shall surely be put to death. The people of the land shall stone him with stones. I will set My face against that man, and will cut him off from his people, because he has given some of his descendants to Molech, to defile My sanctuary and profane My holy name.
