Joshua 10:8-10, 42

And Jehovah said unto Joshua, Fear them not: for I have delivered them into thy hands; there shall not a man of them stand before thee. Joshua therefore came upon them suddenly; for he went up from Gilgal all the night. And Jehovah discomfited them before Israel, and he slew them with a great slaughter at Gibeon, and chased them by the way of the ascent of Beth-horon, and smote them to Azekah, and unto Makkedah.

And all these kings and their land did Joshua take at one time, because Jehovah, the God of Israel, fought for Israel.
