Leviticus 20:2-5

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

‘Any man from the sons of Israel or from the aliens sojourning in Israel 1who gives any of his 2offspring to Molech, shall surely 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 4offspring to Molech, 5so as to defile My sanctuary and 6to profane My holy name. 4If the people of the land, however, 7should ever disregard that man when he gives any of his 8offspring 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 harlot after him, by playing the harlot after Molech.
