Deuteronomy 13:13-16

13some worthless men have gone out from among you and have seduced the inhabitants of their city, saying, ‘1Let’s go and serve other gods’ (whom you have not known),

14then you shall investigate, search out, and inquire thoroughly. And if it is true and the matter is certain that this abomination has been committed among you,

152you shall most certainly strike the inhabitants of that city with the edge of the sword. 3Utterly destroy it and all who are in it and its cattle, with the edge of the sword.

164Then you shall gather all its plunder into the middle of its public square, and burn the city and all its plunder with fire as a whole burnt offering to the Lord your God; and it shall be a 56ruin forever. It shall never be rebuilt.
