Joshua 10:42
“And all these kings and their land did Joshua take at one time, because the Lord God of Israel fought for Israel.”
So Joshua smote all the country of the hills, and of the south, and of the vale, and of the springs, and all their kings: he left none remaining, but utterly destroyed all that breathed, as the Lord God of Israel commanded.
And Joshua smote them from Kadesh–barnea even unto Gaza, and all the country of Goshen, even unto Gibeon.
And all these kings and their land did Joshua take at one time, because the Lord God of Israel fought for Israel.
And Joshua returned, and all Israel with him, unto the camp to Gilgal.
