The effect to the Midianites would be, that they were surrounded by a mighty host. Their own camp being in darkness, as soon as the confusion of flight began they would mistake friends for foes, and fleers for pursuers. When once fighting had begun by the first casual mistake, the clashing of swords and the shouts of the combatants in the camp, accompanied by the continuous blowing of Gideon's trumpets outside, would make it appear that the whole of the enemy was in the camp. Suspicion of treachery on the part of their allies would also be likely to arise in the minds of Midianites, Amalekites, and Arabs. Compare a similar scene in marginal references.

They stood every man in his place - Each of the three companies kept its station, and continued to sound their trumpets. The Midianites seeing this, and believing that they were the trumpets of a numerous army which had then penetrated their camp, were thrown instantly into confusion; and supposing that their enemies were in the midst of them, they turned their swords against every man they met, while at the same time they endeavored to escape for their lives. No stratagem was ever better imagined, better executed, or more completely successful.

And they stood every man in his place around the camp,.... To see the salvation of God, and that it might most clearly appear to be his own doing; and indeed, had they gone into it, they could have done nothing; they had no weapons in their hands, a trumpet in one hand, and a lamp in the other; though this their position served to increase the terror of the enemy, who might suppose that they stood either to light and introduce a large army at the back of them; or to light the forces already in the midst of them, while they destroyed them; which latter seems rather to be the thing their imaginations were possessed with, since they fell to slaying their fellows, supposing them to be enemies, as in the following verse:

and all the host ran, and cried, and fled; or "were broken" (l); as some render the first word, their lines were broken; they could not put themselves in rank and file, but were thrown into the utmost confusion; and cried as being in the utmost danger of their lives, and fled for their safety as fast, as they could; see Isaiah 27:13.

(l) "confracta", Pagninus, Montanus, Vatablus.

And they stood every man in his place round about the camp; and all the host ran, and cried, and fled.

7:21 They stood - As if they had been torch - bearers to the several companies.

7:16-22 This method of defeating the Midianites may be alluded to, as exemplifying the destruction of the devil's kingdom in the world, by the preaching of the everlasting gospel, the sounding that trumpet, and the holding forth that light out of earthen vessels, for such are the ministers of the gospel, 2Co 4:6,7. God chose the foolish things of the world to confound the wise, a barley-cake to overthrow the tents of Midian, that the excellency of the power might be of God only. The gospel is a sword, not in the hand, but in the mouth: the sword of the Lord and of Gideon; of God and Jesus Christ, of Him that sits on the throne and the Lamb. The wicked are often led to avenge the cause of God upon each other, under the power of their delusions, and the fury of their passions. See also how God often makes the enemies of the church instruments to destroy one another; it is a pity that the church's friends should ever act like them.
