Joshua 11:12

12. And all the cities of those kings, etc Having routed the army, they began to plunder and lay waste the country, and to take and demolish the towns. From its being said that the cities which remained entire were not burned, it may be inferred with some probability, that some were taken by force and assault, and so razed. Hazor, alone, after the siege was over, and the heat of the struggle had cooled, was destroyed by fire, because it had held forth the torch which enkindled the war. But in accordance with the explanation already given, it is repeatedly and more clearly stated in this passage, that Joshua did not give loose reins to his passion, when he slew all from the least to the greatest. For there is now a distinct statement of what had not yet been expressed, namely, that Joshua faithfully performed his part, by fulfilling everything which the Lord had enjoined by Moses. It is just as if he had placed his hands at the disposal of God, when he destroyed those nations according to his command. And so ought we to hold that, though the whole world should condemn us, it is sufficient to free us from all blame, that we have the authority of God. Meanwhile, it becomes us prudently to consider what each man’s vocation requires, lest any one, by giving license to his zeal, as wishing to imitate Joshua, may be judged cruel and sanguinary, rather than a strict servant of God.
