Joshua 11:16-20

16So Joshua took all that land, the hill country and all the Negeb and all the land of Goshen and the lowland and the Arabah and the hill country of Israel and its lowland

17from Mount Halak, which rises toward Seir, as far as Baal-gad in the Valley of Lebanon below Mount Hermon. And he captured all their kings and struck them and put them to death.

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

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

20For it was the Lord's doing to harden their hearts that they should come against Israel in battle, in order that they should be devoted to destruction and should receive no mercy but be destroyed, just as the Lord commanded Moses.
