Deuteronomy 13:15-16

AKJV(i) 15 You shall surely smite the inhabitants of that city with the edge of the sword, destroying it utterly, and all that is therein, and the cattle thereof, with the edge of the sword. 16 And you shall gather all the spoil of it into the middle of the street thereof, and shall burn with fire the city, and all the spoil thereof every whit, for the LORD your God: and it shall be an heap for ever; it shall not be built again.
