Deuteronomy 13:16-18

Living Bible

¹⁶ Afterwards you must pile all the booty into the middle of the street and burn it, then put the entire city to the torch, as a burnt offering to Jehovah your God. That city shall forever remain a lifeless mound and may never be rebuilt. ¹⁷ Keep none of the booty! Then the Lord will turn from his fierce anger and be merciful to you, and have compassion upon you, and make you a great nation just as he promised your ancestors.

¹⁸ “Of course, the Lord your God will be merciful only if you have been obedient to him and to his commandments that I am giving you today, and if you have been doing that which is right in the eyes of the Lord.
