Deuteronomy 13:5-15

But that prophet or that dreamer of dreams shall be put to death, because he has counseled rebellion against the LORD your God who brought you from the land of Egypt and redeemed you from the house of slavery, to draw you away from the way in which the LORD your God has commanded you to walk. So you shall remove the evil from among you. “If your brother, the son of your mother, or your son or daughter, or the wife you cherish, or your friend who is as [precious to you as] your own life (soul), entices you secretly, saying, ‘Let us go and serve other gods’ (gods whom neither you nor your fathers have known, of the gods of the peoples who are around you, near you or far from you, from one end of the earth to the other), you shall not consent to him or listen to him; and your eye shall not pity him, nor shall you spare him or conceal him. Instead, you shall most certainly execute him; your hand shall be first [to be raised] against him to put him to death, and afterwards the hand of all the people. So you shall stone him to death with stones, because he has tried to draw you away from the LORD your God who brought you from the land of Egypt, from the house of slavery. Then all Israel will hear and be afraid, and will never again do such a wicked thing among you. “If you hear [it said] in one of your cities, which the LORD your God gives you to live in, that some worthless and evil men have gone out from among you and have tempted the inhabitants of their city [to sin], saying, ‘Let us go and serve other gods’ (whom you have not known), then you shall investigate and search out [witnesses] and ask thorough questions. If it is true and the matter is established that this loathsome thing has been done among you, you shall most certainly strike the inhabitants of that city with the edge of the sword, utterly destroying it and all that is in it, even its livestock with the edge of the sword.
