I. The forces that had dispersed themselves must be followed and smitten. When tidings were brought to Joshua where the kings were he ordered a guard to be set upon them for the present (v. 18), reserving them for another day of destruction, and to be brought forth to a day of wrath, Job xxi. 30. He directs his men to pursue the common soldiers, as much as might be, to prevent their escaping to the garrisons, which would strengthen them, and make the reduction of them the more difficult, v. 19. Like a prudent general, he does that first which is most needful, and defers his triumphs till he has completed his conquests; nor was he in such haste to insult over the captive kings but that he would first prevent the rallying again of their scattered forces. The result of this vigorous pursuit was, 1. That a very great slaughter was made of the enemies of God and Israel. And, 2. The field was cleared of them, so that none remained but such as got into fenced cities, where they would not long be safe themselves, nor were they capable of doing any service to the cities that sheltered them, unless they could have left their fears behind them. 3. None moved his tongue against any of the children of Israel, v. 21. This expression intimates, (1.) Their perfect safety and tranquillity; some think it should be read (from Exod. xi. 7), Against any of the children of Israel did not a dog move his tongue; no, not against any one man of them. They were not threatened by any danger at all after their victory, no, not so much as the barking of a dog. Not one single Israelite (for the original makes it so particular) was brought into any distress, either in the battle or in the pursuit. (2.) Their honour and reputation; no man had any reproach to cast upon them, nor an ill word to give them. God not only tied the hands, but stopped the mouths, of their enraged enemies, and put lying lips to silence. (3.) The Chaldee paraphrase makes it an expression of their unalloyed joy for this victory, reading it, There was no hurt nor loss to the children of Israel, for which any man should afflict his soul. When the army came to be reviewed after the battle, there was none slain, none wounded, none missing. Not one Israelite had occasion to lament either the loss of a friend or the loss of a limb, so cheap, so easy, so glorious, was this victory.
