Joshua 11:13-17

However, Israel did not burn any cities that stood on their mounds, except Hazor alone, which Joshua burned.

And all the spoils of these cities and the cattle, the sons of Israel took as their plunder; but they struck every person with the edge of the sword, until they had destroyed them. They left no one breathing.

Just as the Lord had commanded His servant Moses, so Moses commanded Joshua, and so Joshua did; he left nothing undone of all that the Lord had commanded Moses.

So Joshua took all that land: the hill country and all the Negev, all the land of Goshen, the lowland, the Arabah, the hill country of Israel and its lowland

from Mount Halak, that rises toward Seir, even as far as Baal-gad in the Valley of Lebanon at the foot of Mount Hermon. And he captured all their kings, and struck them and put them to death.
