Deuteronomy 13:6-15

6If your very own brother, or your son or daughter, or the wife you love, or your closest friend secretly entices you, saying, “Let us go and worship other gods” (gods that neither you nor your ancestors have known, 7gods of the peoples around you, whether near or far, from one end of the land to the other), 8do not yield to them or listen to them. Show them no pity. Do not spare them or shield them. 9You must certainly put them to death. Your hand must be the first in putting them to death, and then the hands of all the people. 10Stone them to death, because they tried to turn you away from the LORD your God, who brought you out of Egypt, out of the land of slavery.

11Then all Israel will hear and be afraid, and no one among you will do such an evil thing again. 12If you hear it said about one of the towns the LORD your God is giving you to live in 13that troublemakers have arisen among you and have led the people of their town astray, saying, “Let us go and worship other gods” (gods you have not known), 14then you must inquire, probe and investigate it thoroughly. And if it is true and it has been proved that this detestable thing has been done among you, 15you must certainly put to the sword all who live in that town. You must destroy it completely, The Hebrew term refers to the irrevocable giving over of things or persons to the Lord, often by totally destroying them. both its people and its livestock.
