Leviticus 20:1-7

20:1 And the LORD spake unto Moses, saying, 20:2 Again, thou shalt say to the children of Israel, Whosoever [he be] of the children of Israel, or of the strangers that sojourn in Israel, that giveth [any] of his seed unto Molech; he shall surely be put to death: the people of the land shall stone him with stones. 20:3 And I will set my face against that man, and will cut him off from among his people; because he hath given of his seed unto Molech, to defile my sanctuary, and to profane my holy name. 20:4 And if the people of the land do any ways hide their eyes from the man, when he giveth of his seed unto Molech, and kill him not: 20:5 Then I will set my face against that man, and against his family, and will cut him off, and all that go a whoring after him, to commit whoredom with Molech, from among their people. 20:6 And the soul that turneth after such as have familiar spirits, and after wizards, to go a whoring after them, I will even set my face against that soul, and will cut him off from among his people. 20:7 Sanctify yourselves therefore, and be ye holy: for I [am] the LORD your God.

Leviticus 20:26

20:26 And ye shall be holy unto me: for I the LORD [am] holy, and have severed you from [other] people, that ye should be mine.
