Deuteronomy 13:9-11

New Revised Standard Version, Anglicised Catholic Edition

⁹ But you shall surely kill them; your own hand shall be first against them to execute them, and afterwards the hand of all the people. ¹⁰ Stone them to death for trying to turn you away from the Lord your God, who brought you out of the land of Egypt, out of the house of slavery. ¹¹ Then all Israel shall hear and be afraid, and never again do any such wickedness.
