Leviticus 20:1-3

Then the LORD spoke to Moses, saying, “You shall also say to the sons of Israel: ‘ A ny man from the sons of Israel or from the aliens sojourning in Israel who gives any of his offspring to Molech, shall surely be put to death; the people of the land shall stone him with stones. I will also set My face against that man and will cut him off from among his people, because he has given some of his offspring to Molech, so as to defile My sanctuary and to profane My holy name.
