Jabin, king of Hazor, hears what happened in the south and sends messages to other kings of the north, of Madon, Shimron, Achshaph and of the hill country and the plain. They unite with an army as numerous as the sand on the seashore, with very many horses and chariots, and camp together at the waters of Merom to fight Israel.
The Lord tells Joshua not to fear them, for the next day he will hand them over slain before Israel; Joshua is to hamstring their horses and burn their chariots. Joshua and all his army attack them suddenly at the waters of Merom. The Lord gives them into the hand of Israel, who pursue them as far as Great Sidon, Misrephoth-maim and the Valley of Mizpeh, until none are left. Joshua does to the horses and chariots as the Lord told him.
Then Joshua turns back and takes Hazor, which was formerly the head of all those kingdoms. They kill all its inhabitants and burn it. Of the cities standing on their mounds, Israel burned none except Hazor. Israel takes the plunder and the livestock and destroys the people, just as the Lord had commanded Moses and Moses commanded Joshua, with Joshua leaving nothing undone of all that was commanded.
The chapter summarizes that Joshua took the whole land: the hill country, the Negeb, the lowland and the mountains of Israel. No city made peace with Israel except the Hivites of Gibeon; the Lord had hardened the hearts of the rest so that they would fight and be destroyed. Joshua also cut off the Anakim from the hill country, and only some remained in Gaza, Gath and Ashdod. So Joshua took the whole land according to all that the Lord had told Moses, gave it as an inheritance to Israel by their tribes, and the land had rest from war.
