Leviticus 20:5-7

New Revised Standard Version Catholic Edition

⁵ I myself will set my face against them and against their family, and will cut them off from among their people, them and all who follow them in prostituting themselves to Molech.

⁶ If any turn to mediums and wizards, prostituting themselves to them, I will set my face against them, and will cut them off from the people. ⁷ Consecrate yourselves therefore, and be holy; for I am the Lord your God.
