Leviticus 20:2-3

2“You shall also say to the sons of Israel:

‘Anyone from the sons of Israel or from the strangers residing in Israel 1who gives any of his 2children to Molech, shall certainly be put to death; 3the people of the land shall stone him with stones. 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 4children to Molech, 5so as to defile My sanctuary and 6to profane My holy name.
