31 Joshua, all Israel with him, moved on from Libnah to Lachish. He set up camp nearby and attacked. 32 God gave Lachish to Israel. Israel took it in two days and killed everyone. He carried out the holy curse, the same as with Libnah. 33 Horam, king of Gezer, arrived to help Lachish. Joshua attacked him and his army until there was nothing left of them. No survivors.

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?
