Deuteronomy 13:7-9

Amplified Bible

⁷ of the gods of the peoples who are around you, near you or far from you, from one end of the earth to the other), ⁸ you shall not consent to him or listen to him; and your eye shall not pity him, nor shall you spare him or conceal him. ⁹ Instead, you shall most certainly execute him; your hand shall be first [to be raised] against him to put him to death, and afterwards the hand of all the people.
