Joshua 11:16-20

Thus Joshua took all that land: the hill country and all the Negev, all that 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 down and put them to death. Joshua waged war a long time with all these kings. There was not a city which made peace with the sons of Israel except the Hivites living in Gibeon; they took them all in battle. For it was of the LORD to harden their hearts, to meet Israel in battle in order that he might utterly destroy them, that they might receive no mercy, but that he might destroy them, just as the LORD had commanded Moses.
