Joshua 11:13

But as for the cities that stood still in their strength, Israel burned none of them, save Hazor only; that did Joshua burn.

But as for the cities that stood still in their strength,.... Whose walls were not demolished when taken, as Kimchi and Jarchi interpret it, or that "stood upon their heaps" {y}; upon an eminence, being built on hills and mountains:

Israel burned none of them; but reserved them for their own habitations, being well fortified, and having no need of new walls being built to them, or being in a very agreeable situation:

save Hazor only, that did Joshua burn; because it was the chief city where the scheme was formed, and the combination against Israel was made, and was the rendezvous of the confederate forces against them: the Jews have a tradition {z}, that God said to Moses, and Moses said to Joshua, that he should burn it, and that only.
