Deuteronomy 13:6-10

“Suppose someone secretly entices you—even your brother, your son or daughter, your beloved wife, or your closest friend—and says, ‘Let us go worship other gods’—gods that neither you nor your ancestors have known. They might suggest that you worship the gods of peoples who live nearby or who come from the ends of the earth. But do not give in or listen. Have no pity, and do not spare or protect them. You must put them to death! Strike the first blow yourself, and then all the people must join in. Stone the guilty ones to death because they have tried to draw you away from the LORD your God, who rescued you from the land of Egypt, the place of slavery.
