Deuteronomy 13:8-10

Revised Standard Version Catholic Edition

⁸ you shall not yield to him or listen to him, nor shall your eye pity him, nor shall you spare him, nor shall you conceal him; ⁹ but you shall kill him; your hand shall be first against him to put him to death, and afterwards the hand of all the people. ¹⁰ You shall stone him to death with stones, because he sought to draw you away from the Lord your God, who brought you out of the land of Egypt, out of the house of bondage.
