Verse 10: And Joshua at that time turned back, and took Hazor, and smote the king thereof with the sword: for Hazor beforetime was the head of all those kingdoms.
[And returning, he took Hazor] He is rightly said to have returned, for far beyond this city in all directions he had pursued his enemies (Masius).
[And he smote the king thereof] Either, he had already previously smitten him in the battle (Malvenda out of Masius); or, Jabin escaped unto his palace out of the hands of those hunting him, and so Joshua returned here, so that he might fall upon the originator of this war, even at that time fearful after his flight (Masius). Or, this was another, whom they recently had appointed into the place of the dead kig (Malvenda out of Masius).
Smote the king thereof; either in the former battle, though it be mentioned here; or rather in his royal city, to which he fled out of the battle.
[Hazor…was holding the supremacy] Understand this of that part of Canaan with which we are concerned (Masius, Lapide, Bonfrerius). That is to say, Joshua attacked it, because it was chief of cities, and therefore the most well-fortified, with which captured the approach to the others would be easier (Bonfrerius). Where kingdoms are small, one of the Kings is wont to be chosen, who might take the lead in war: which histories witness to be done in Japan, Java, and other places of the Orient (Grotius).
The head of all those kingdoms; not of all Canaan, but of all those who were confederate with him in this expedition.
[He did not leave in it any remnants] Understand, not that all were pursued, but that of however many were able to be pursued they did not spare any life (Bonfrerius, Masius). For some escaped by flight, either at that time, or previously, who after the death of Joshua recovered strength, and restored the cities, and appointed new Kings for themselves, whom they also called by the names of the former Kings, according to custom. Hence Jabin afflicted Israel, Judges 4 (Lapide out of Masius). Hence the Midianites, cut off by Moses, Numbers 31, grew up again, and were prostrated by Gideon, Judges 6. So also the Hebronites, here in verse 21, compared with Judges 1:10 (Lapide).
There was not any, that is, no human person.
