Joshua 10:39-40

They took the city, its king and its villages, and put them to the sword. Everyone in it they totally destroyed. They left no survivors. They did to Debir and its king as they had done to Libnah and its king and to Hebron. So Joshua subdued the whole region, including the hill country, the Negev, the western foothills and the mountain slopes, together with all their kings. He left no survivors. He totally destroyed all who breathed, just as the LORD, the God of Israel, had commanded.
