Deuteronomy 13:15-16

15you shall surely put the inhabitants of that city to the sword, devoting it to destruction,
That is, setting apart ( devoting) as an offering to the Lord (for destruction)
all who are in it and its cattle, with the edge of the sword.
16You shall gather all its spoil into the midst of its open square and bburn the city and all its spoil with fire, as a whole burnt offering to the Lord your God. It shall be a cheap forever. It shall not be built again.
