Joshua 11:18

16 So Joshua captured all that land, the hill country, all the South, all the land of Goshen, the lowland, the Arabah, the hill country of Israel, and the lowland of the same,

17 from Mount Halak, that goes up to Seir, even to Baal Gad in the valley of Lebanon under Mount Hermon. He took all their kings, struck them, and put them to death.

18 Joshua made war a long time with all those kings.

19 There was not a city that made peace with the children of Israel, except the Hivites, the inhabitants of Gibeon. They took all in battle.

20 For it was of the LORD to harden their hearts, to come against Israel in battle, that he might utterly destroy them, that they might have no favor, but that he might destroy them, as the LORD commanded Moses.
