Joshua 11:16-20

16So Joshua took this entire land: the hill country, all the Negev, the whole region of Goshen, the western foothills, the Arabah and the mountains of Israel with their foothills, 17from Mount Halak, which rises toward Seir, to Baal Gad in the Valley of Lebanon below Mount Hermon. He captured all their kings and put them to death. 18Joshua waged war against all these kings for a long time. 19Except for the Hivites living in Gibeon, not one city made a treaty of peace with the Israelites, who took them all in battle.

20For it was the LORD himself who hardened their hearts to wage war against Israel, so that he might destroy them totally, exterminating them without mercy, as the LORD had commanded Moses.
