God established ethical principles and required serious penalties for flagrant sins to separate His people from the evil practices of foreign nations:
• Those who offer their children to Molech will be cut off from among the people (v. 2-5)
• Those who follow witches and familiar spirits will be cut off from among the people (v. 6)
• Those who curse their father and mother shall be put to death (v. 9)
• Those who commit adultery shall be put to death (v. 10)
• Those who have sexual relations with a relative other than a spouse shall be put to death (v. 11-12, 14)
• Men who have relationships with men shall be put to death (v. 13)
• Those who commit bestiality shall be put to death (v. 15-16)
• Those who uncover the nakedness of a relative shall be penalized (v. 17, 19-21)
