We have here the same improvement made of this victory as was made of that in the foregoing chapter. 1. The destruction of Hazor is particularly recorded, because in it, and by the king thereof, this daring design against Israel was laid, Jos 11:10, Jos 11:11. The king of Hazor, it seems, escaped with his life out of the battle, and thought himself safe when he had got back into his own city, and Joshua had gone in pursuit of the scattered troops another way. But it proved that that which he thought would be for his welfare was his trap; in it he was taken as in an evil net; there he was slain, and his city, for his sake, burned. Yet we find that the remains of it being not well looked after by Israel the Canaanites rebuilt it, and settled there under another king of the same name, Jdg 4:2. 2. The rest of the cities of that part of the country are spoken of only in general, that Joshua got them all into his hands, but did not burn them as he did Hazor, for Israel was to dwell in great and goodly cities which they builded not (Deu 6:10) and in these among the rest. And here we find Israel rolling in blood and treasure. (1.) In the blood of their enemies; they smote all the souls (Jos 11:1), neither left they any to breathe (Jos 11:14), that there might be none to infect them with the abominations of Canaan, and none to disturb them in the possession of it. The children were cut off, lest they should afterwards lay claim to any part of this land in the right of their parents. (2.) In the wealth of their enemies. The spoil, and the cattle, they took for a prey to themselves, Jos 11:14. As they were enriched with the spoil of their oppressors when they came out of Egypt, wherewith to defray the charges of their apprenticeship in the wilderness, so they were now enriched with the spoil of their enemies for a stock wherewith to set up in the land of Canaan. Thus is the wealth of the sinner laid up for the just.

The cities that stood still in their strength - The word תלם tillam, which we translate their strength, and the margin, their heap, has been understood two ways.
1. As signifying those cities which had made peace with the Israelites, when conditions of peace were offered according to the command of the law; and consequently were not destroyed. Such as the cities of the Hivites; see Jos 11:19.
2. The cities which were situated upon hills and mountains, which, when taken, might be retained with little difficulty. In this sense the place is understood by the Vulgate, as pointing out the cities quae erant in collibus et tumulis sitae, "which were situated on hills and eminences." As the cities of the plain might be easily attacked and carried, Joshua destroyed them; but as those on mountains, hills, or other eminences, might be retained with little trouble, prudence would dictate their preservation, as places of refuge in any insurrection of the people, or invasion of their adversaries. The passage in Jeremiah, Jer 30:18, Jerusalem shall be builded on her own heap, תלה tillah, if understood as above, conveys an easy and clear sense: Jerusalem shall be re-established on her Own Hill.

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.

(y) "super tumulum eorum", Montanus; "quae erant in collibus et in tamulis sitae", V. L. (z) Bereshit Rabba, sect. 81. fol. 71. 1.

as for the cities that stood still in their strength--literally, "on their heaps." It was a Phœnician custom to build cities on heights, natural or artificial [HENGSTENBERG].
