29 And Joshua passed from Makkedah, and all Israel with him, unto Libnah, and fought against Libnah: 30 and Jehovah delivered it also, and the king thereof, into the hand of Israel; and he smote it with the edge of the sword, and all the souls that were therein; he left none remaining in it; and he did unto the king thereof as he had done unto the king of Jericho. 31 And Joshua passed from Libnah, and all Israel with him, unto Lachish, and encamped against it, and fought against it: 32 and Jehovah delivered Lachish into the hand of Israel; and he took it on the second day, and smote it with the edge of the sword, and all the souls that were therein, 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?
