Leviticus 20:5-8

⁵then I will set my face against that man and against his family, and will cut him off, and all who play the prostitute after him to play the prostitute with Molech, from amongst their people.

⁶“‘The person that turns to those who are mediums and wizards, to play the prostitute after them, I will even set my face against that person, and will cut him off from amongst his people.

⁷“‘Sanctify yourselves therefore, and be holy; for I am the LORD your God.

⁸You shall keep my statutes, and do them. I am the LORD who sanctifies you.
