1) If your own full brother, or your son or daughter, or your beloved wife, or you intimate friend, entices you secretly to serve other gods, whom you and your fathers have not known, gods of any other nations, near at hand or far away, from one end of the earth to the other: do not yield to him or listen to him, nor look with pity upon him, to spare or shield him, but kill him. Your hand shall be the first raised to slay him; the rest of the people shall join in with you. You shall stone him to death, because he sought to lead you astray from the Lord, your God, who brought you out of the land of Egypt, that place of slavery. And all Israel, hearing of this, shall fear and never do such evil as this in your midst. (Deuteronomy 13:7-12 NAB)
2) Suppose a man or woman among you, in one of your towns that the LORD your God is giving you, has done evil in the sight of the LORD your God and has violated the covenant by serving other gods or by worshiping the sun, the moon, or any of the forces of heaven, which I have strictly forbidden. When you hear about it, investigate the matter thoroughly. If it is true that this detestable thing has been done in Israel, then that man or woman must be taken to the gates of the town and stoned to death. (Deuteronomy 17:2-5 NLT)
