Deuteronomy 13:13-15

New Century Version

¹³ that evil people have moved in among you. And they might lead the people of that city away from God, saying, “Let’s go and worship other gods.” (These are gods you have not known.) ¹⁴ Then you must ask about it, looking into the matter and checking carefully whether it is true. If it is proved that a hateful thing has happened among you, ¹⁵ you must kill with a sword everyone who lives in that city. Destroy the city completely and kill everyone in it, as well as the animals, with a sword.
