31 Then Joshua and all Israel with him went on from Libnah to Lachish, and took up their position against it and made an attack on it, 32 And the Lord gave Lachish into the hands of Israel, and on the second day he took it, putting it and every person in it to the sword without mercy, as he had done to Libnah. 33 Then Horam, king of Gezer, came up to the help of Lachish; and Joshua overcame him and his people, putting all of them to death.

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?
