Joshua 11:18 KJV

16So Joshua took all that land, the hills, and all the south country, and all the land of Goshen, and the valley, and the plain, and the mountain of Israel, and the valley of the same;

17Even from the mount Halak, that goeth up to Seir, even unto Baalgad in the valley of Lebanon under mount Hermon: and all their kings he took, and smote them, and slew them.

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

19There was not a city that made peace with the children of Israel, save the Hivites the inhabitants of Gibeon: all other they took in battle.

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