1-8. God provides that the praise of victory may be wholly to himself, by appointing only three hundred men to be employed. Activity and prudence go with dependence upon God for help in our lawful undertakings. When the Lord sees that men would overlook him, and through unbelief, would shrink from perilous services, or that through pride they would vaunt themselves against him, he will set them aside, and do his work by other instruments. Pretences will be found by many, for deserting the cause and escaping the cross. But though a religious society may thus be made fewer in numbers, yet it will gain as to purity, and may expect an increased blessing from the Lord. God chooses to employ such as are not only well affected, but zealously affected in a good thing. They grudged not at the liberty of the others who were dismissed. In doing the duties required by God, we must not regard the forwardness or backwardness of others, nor what they do, but what God looks for at our hands. He is a rare person who can endure that others should excel him in gifts or blessings, or in liberty; so that we may say, it is by the special grace of God that we regard what God says to us, and not look to men what they do.
Verses 9-15 The dream seemed to have little meaning in it; but the interpretation evidently proved the whole to be from the Lord, and discovered that the name of Gideon had filled the Midianites with terror. Gideon took this as a sure pledge of success; without delay he worshipped and praised God, and returned with confidence to his three hundred men. Wherever we are, we may speak to God, and worship him. God must have the praise of that which encourages our faith. And his providence must be acknowledged in events, though small and seemingly accidental.
Verses 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, 2Co. 4:7 . 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.
Verses 23-25 Two chief commanders of the host of Midian were taken and slain by the men of Ephraim. It were to be wished that we all did as these did, and that where help is needed, that it were willingly and readily performed by another. And that if there were any excellent and profitable matter begun, we were willing to have fellow-labourers to the finishing and perfecting the same, and not, as often, hinder one another.
