Joshua 10:40-42

So Joshua defeated all the kings of the cities of these areas: the mountains, southern Canaan, the western hills, and the slopes. The LORD, the God of Israel, had told Joshua to completely destroy all the people as an offering to the LORD, so he left no one alive in those places. Joshua captured all the cities from Kadesh Barnea to Gaza, and from Goshen to Gibeon. He captured all these cities and their kings on one trip, because the LORD, the God of Israel, was fighting for Israel.
