Leviticus 20:1-3

¹And the Lord spake with Mosheh, saying,

²Speak unto the sons of Israel: Whatever man of the sons of Israel, or of the strangers who sojourn in Israel, giveth his offspring unto Molek, with killing shall he be killed; the people of the house of Israel shall stone him with stones.

³And I will show My displeasure against that man, and will destroy from among his people, because he hath given his offspring unto Molek, to defile My sanctuary and to profane My holy Name.
