39 And he took it and its king and all its cities; they struck them with the edge of the sword and utterly destroyed all the people who were in it. He left none remaining; as he had done to Hebron, so he did to Debir and its king, as he had done also to Libnah and its king. 40 So Joshua conquered all the land: the mountain country and the South and the lowland and the wilderness slopes, and all their kings; he left none remaining, but utterly destroyed all that breathed, as the Lord God of Israel had commanded. 41 And Joshua conquered them from Kadesh Barnea as far as Gaza, and all the country of Goshen, even as far as Gibeon. 42 All these kings and their land Joshua took at one time, because the Lord God of Israel fought for Israel. 43 Then Joshua returned, and all Israel with him, to the camp at Gilgal.

Commentary on Joshua 10:28-43
(Read Joshua 10:28-43)
Joshua made speed in taking these cities. See what a great deal of work may be done in a little time, if we will be diligent, and improve our opportunities. God here showed his hatred of the idolatries and other abominations of which the Canaanites had been guilty, and shows us how great the provocation was, by the greatness of the destruction brought upon them. Here also was typified the destruction of all the enemies of the Lord Jesus, who, having slighted the riches of his grace, must for ever feel the weight of his wrath. The Lord fought for Israel. They could not have gotten the victory, if God had not undertaken the battle. We conquer when God fights for us; if he be for us, who can be against us?
