Deuteronomy 13:9-11

New Catholic Bible

⁹ you are not to agree to do this with him or even listen to him. You must show him no pity, you should not spare or conceal him. ¹⁰ You must put him to death. You must be the first to lay hands on him to put him to death, and then all of the people after you. ¹¹ Stone him to death! He sought to turn you away from the Lord, your God, who brought you out of the land of Egypt, out of the land of slavery.
