Deuteronomy 13:16-19 New American Bible, Revised Edition (NABRE)

16. you shall put the inhabitants of that city to the sword, placing the city and all that is in it, even its livestock, under the ban.

17. Having heaped up all its spoils in the middle of its square, you shall burn the city with all its spoils as a whole burnt offering to the Lord, your God. Let it be a heap of ruins forever, never to be rebuilt.

18. You shall not hold on to anything that is under the ban; then the Lord will turn from his burning anger and show you mercy, and in showing you mercy multiply you as he swore to your ancestors,

19. because you have listened to the voice of the Lord, your God, keeping all his commandments, which I give you today, doing what is right in the sight of the Lord, your God.
