II. The wonderful success of this alarm. The Midianites were shouted out of their lives, as the walls of Jericho were shouted down, that Gideon might see what he lately despaired of ever seeing, the wonders that their fathers told them of. Gideon's soldiers observed their orders, and stood every man in his place round about the camp (v. 21), sounding his trumpet to excite them to fight one another, and holding out his torch to light them to their ruin. They did not rush into the host of Midian, as greedy either of blood or spoil, but patiently stood still to see the salvation of the Lord, a salvation purely of his own working. Observe how the design took effect. 1. They feared the Israelites. All the host immediately took the alarm; it flew like lightning through all their lines, and they ran, and cried, and fled, v. 21. There was something natural in this fright. We may suppose they had not had intelligence of the great diminution of Gideon's army, but rather concluded that since their last advices it had been growing greater and greater; and therefore they had reason to suspect, knowing how odious and grievous they had made themselves and what bold steps had been taken towards the throwing off of their yoke, that it was a very great army which was to be ushered in with all those trumpeters and torch-bearers. But there was more of a supernatural power impressing this terror upon them. God himself gave it the setting on, to show how that promise should have been fulfilled if they had not forfeited it, One of you shall chase a thousand. See the power of imagination, and how much it may become a terror at some times, as at other times it is a pleasure. 2. They fell foul upon one another: The Lord set every man's sword against his fellow, v. 22. In this confusion, observing the trumpeters and torch-bearers to stand still without their camp, they concluded the body of the army had already entered and was in the midst of them, and therefore every one ran at the next he met, though a friend, supposing him an enemy, and one such mistake as this would occasion many, for then he that slew him would certainly be taken for an enemy, and would be dispatched immediately. It is our interest to preserve such a command of our own spirits as never to be afraid with any amazement, for we cannot conceive what mischiefs we thereby plunge ourselves into. See also how God often makes the enemies of his church instruments to destroy one another; it is a pity the church's friends should ever be thus infatuated. 3. They fled for their lives. Perhaps when day-light came they were sensible of their mistake in fighting with one another, and concluded that by this fatal error they had so weakened themselves that now it was impossible to make any head against Israel, and therefore made the best of their way towards their own country, though, for aught that appears, the 300 men kept their ground. The wicked flee when none pursueth, Prov. xxviii. 1. Terrors make him afraid on every side, and drive him to his feet, Job xviii. 11.
