Joshua 11:20-21

For 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. At that time Joshua went and destroyed the Anakites from the hill country: from Hebron, Debir and Anab, from all the hill country of Judah, and from all the hill country of Israel. Joshua totally destroyed them and their towns.
