Joshua 11:16-20

16So Joshua took all this land: the hill country, all the Negev (South country), all the land of Goshen, the lowland, the Arabah [plain], the hill country of Israel and its lowland

17from Mount Halak, that rises toward Seir [in the south], even as far as Baal-gad in the Valley of Lebanon at the foot of Mount Hermon [in the north]. He captured all their kings and struck them and put them to death.

18Joshua waged war with all these kings a long time [at least five years].

19There was no city that made peace with the Israelites except the Hivites living in Gibeon; they took all the others in battle.

20For it was [the purpose] of the Lord to harden their hearts, to meet Israel in battle so that Israel would utterly destroy them, that they would receive no mercy, but that Israel would destroy them, just as the Lord had commanded Moses.
