Deuteronomy 13:1-11Revised Standard Version (RSV)
13 “If a prophet arises among you, or a dreamer of dreams, and gives you a sign or a wonder, 2 and the sign or wonder which he tells you comes to pass, and if he says, ‘Let us go after other gods,’ which you have not known, ‘and let us serve them,’ 3 you shall not listen to the words of that prophet or to that dreamer of dreams; for the Lord your God is testing you, to know whether you love the Lord your God with all your heart and with all your soul. 4 You shall walk after the Lord your God and fear him, and keep his commandments and obey his voice, and you shall serve him and cleave to him. 5 But that prophet or that dreamer of dreams shall be put to death, because he has taught rebellion against the Lord your God, who brought you out of the land of Egypt and redeemed you out of the house of bondage, to make you leave the way in which the Lord your God commanded you to walk. So you shall purge the evil from the midst of you.
6 “If your brother, the son of your mother, or your son, or your daughter, or the wife of your bosom, or your friend who is as your own soul, entices you secretly, saying, ‘Let us go and serve other gods,’ which neither you nor your fathers have known, 7 some of the gods of the peoples that are round about you, whether near you or far off from you, from the one end of the earth to the other, 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. 11 And all Israel shall hear, and fear, and never again do any such wickedness as this among you.
