Joshua 10:37

The king, viz., the new king, who succeeded him that was slain, ver. 26. (Challoner) --- Caleb afterwards took Hebron, which, it seems, the Chanaanites had seized again and fortified, while Josue was conquering other parts of the country. He could not leave garrisons in all the cities which he took, and hence he set many of them on fire. After the strength of the country was broken, he knew that the Israelites might easily subdue the few isolated cities which he was forced to leave behind. But they proved so negligent, that many places were left in the possession of the Chanaanites, which proved a stumbling block to God's people.
