29 Then Joshua passed from Makkedah, and all Israel with him, to Libnah; and they fought against Libnah. 30 And the Lord also delivered it and its king into the hand of Israel; he struck it and all the people who were in it with the edge of the sword. He let none remain in it, but did to its king as he had done to the king of Jericho. 31 Then Joshua passed from Libnah, and all Israel with him, to Lachish; and they encamped against it and fought against it. 32 And the Lord delivered Lachish into the hand of Israel, who took it on the second day, and struck it and all the people who were in it with the edge of the sword, according to all that he had done to Libnah.

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?
