Joshua 10:40-42

So Joshua conquered the whole region—the kings and people of the hill country, the Negev, the western foothills, and the mountain slopes. He completely destroyed everyone in the land, leaving no survivors, just as the LORD, the God of Israel, had commanded. Joshua slaughtered them from Kadesh-barnea to Gaza and from the region around the town of Goshen up to Gibeon. Joshua conquered all these kings and their land in a single campaign, for the LORD, the God of Israel, was fighting for his people.
