Joshua 11:16-20

16So Joshua captured all this land: the hill country, the Negev, all the land of Goshen, the lowland, the Arabah, the hill country of Israel and its lowland,

17from the Mount Halak that ascends to Seir all the way to Baal-gad in the valley of Lebanon at the foot of Mount Hermon. He captured all their kings, struck them down and put them to death.

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

19There was not a city that made peace with Bnei-Yisrael except the Hivites who inhabited Gibeon. All the rest they took in battle.

20For it was of Adonai to harden their hearts to encounter Israel in battle, that they might be put to the ban, that they might receive no mercy, in order to destroy them as Adonai had commanded Moses.
