2 And the Lord said to Gideon, So great is the number of your people, that if I give the Midianites into their hands they will be uplifted in pride over me and will say, I myself have been my saviour. 3 So now, let it be given out to the people that anyone who is shaking with fear is to go back from Mount Galud. So twenty-two thousand of the people went back, but there were still ten thousand. 4 Then the Lord said to Gideon, There are still more people than is necessary; take them down to the water so that I may put them to the test for you there; then whoever I say is to go with you will go, and whoever I say is not to go will not go. 5 So he took the people down to the water; and the Lord said to Gideon, Put on one side by themselves all those drinking up the water with their tongues like a dog; and in the same way, all those who go down on their knees to the water while drinking. 6 Now the number of those who took up the water with their tongues was three hundred; all the rest of the people went down on their knees to the water. 7 And the Lord said to Gideon, By those three hundred who were drinking with their tongues I will give you salvation and give the Midianites into your hands; let the rest of the people go away, every man to his place. 8 So they took the vessels of the people, and their horns from their hands, and he sent them away, every man to his tent, keeping only the three hundred; and the tents of Midian were lower down in the valley.

Commentary on Judges 7:1-8.
(Read Judges 7:1-8.)
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.
