Deuteronomy 13:12-16 New Revised Standard Version (NRSV)
12 If you hear it said about one of the towns that the Lord your God is giving you to live in, 13 that scoundrels from among you have gone out and led the inhabitants of the town astray, saying, “Let us go and worship other gods,” whom you have not known, 14 then you shall inquire and make a thorough investigation. If the charge is established that such an abhorrent thing has been done among you, 15 you shall put the inhabitants of that town to the sword, utterly destroying it and everything in it—even putting its livestock to the sword. 16 All of its spoil you shall gather into its public square; then burn the town and all its spoil with fire, as a whole burnt offering to the Lord your God. It shall remain a perpetual ruin, never to be rebuilt.
