Every one that lappeth of the water - as a dog - The original word ילק yalok is precisely the sound which a dog makes when he is drinking.

So he brought them down to the water,.... His whole army of 10,000 men:

and the Lord said unto Gideon, everyone that lappeth of the water with his tongue, as a dog lappeth, him shall thou set by himself; this has led some, as particularly Grotius, to think of the Egyptian dogs; of whom Aelianus relates (b), that they do not drink at once freely, and to satiety, being afraid of the crocodiles in the river; but run about the bank, and by stealth snatch a little here and a little there, and so satisfy themselves: but the allusion here is to dogs in common, whose usual way it is not to sup in, and drink a drought, but by putting out their tongues to lick and lap water with them, as Aristotle (c) says all creatures do that have teeth like saws; and the likeness between the drinking of these men, to be observed lay not in anything else but in the single action of lapping; for they first took the water in the hollow of their hands, out of the stream, and then lapped it, as in Judges 7:6 whereas a dog does not and cannot take water that way; and this lapping was standing upright, whereas dogs in common, as Aelianus in the same place suggests, bow themselves, and lap as much water as will satisfy their thirst; and by this these men were distinguished from those that bowed on their knees to drink; for had they not taken up water in their hands, they must have bowed down on their knees to have lapped, as well as those did, to sup it, or take in a large draught of it; now all those that thus lapped were to be set apart by themselves; but whether they were to go with Gideon or not, as yet he knew not: likewise everyone that boweth down on his knee to drink; were to be set by themselves also, but which of those were to go with him is after related.

(b) Var. Hist. l. 1. c. 4. (c) Hist. Animal. l. 8. c. 6.

Gideon was to divide the people by putting all those who should lick the water with their tongue as a dog licketh into one class, and all those who knelt down to drink into another, and so separating the latter from the former. The number of those who licked the water into their mouth with their hand amounted to 300, and all the rest knelt down to drink. "To lick with their hand to their mouth," i.e., to take the water from the brook with the hollow of their hand, and lap it into the mouth with their tongue as a dog does, is only a more distinct expression for "licking with the tongue." The 300 men who quenched their thirst in this manner were certainly not the cowardly or indolent who did not kneel down to drink in the ordinary way, either from indolence or fear, as Josephus, Theodoret, and others supposed, but rather the bravest-namely those who, when they reached a brook before the battle, did not allow themselves time to kneel down and satisfy their thirst in the most convenient manner, but simply took up some water with their hands as they stood in their military accoutrements, to strengthen themselves for the battle, and then proceeded without delay against the foe. By such a sign as this, Bertheau supposes that even an ordinary general might have been able to recognise the bravest of his army. No doubt: but if this account had not been handed down, it is certain that it would never have occurred to an ordinary or even a distinguished general to adopt such a method of putting the bravery of his troops to the test; and even Gideon, the hero of God, would never have thought of diminishing still further through such a trial an army which had already become so small, or of attempting to defeat an army of more than 100,000 men by a few hundred of the bravest men, if the Lord himself had not commanded it.

Whilst the Lord was willing to strengthen the feeble faith of Gideon by the sign with the fleece of wool, and thus to raise him up to full confidence in the divine omnipotence, He also required of him, when thus strengthened, an attestation of his faith, by the purification of his army that he might give the whole glory to Him, and accept the victory over that great multitude from His hand alone.

So he brought down the people unto the water: and the LORD said unto Gideon, Every one that lappeth of the water with his tongue, as a dog lappeth, him shalt thou set by himself; {c} likewise every one that boweth down upon his knees to drink.

(c) Let them depart as unfit for this enterprise.

5. bring them down unto the water-When the wandering people in Asia, on a journey or in haste, come to water, they do not stoop down with deliberation on their knees, but only bend forward as much as is necessary to bring their hand in contact with the stream, and throw it up with rapidity, and at the same time such address, that they do not drop a particle. The Israelites, it seems, were acquainted with the practice; and those who adopted it on this occasion were selected as fit for a work that required expedition. The rest were dismissed according to the divine direction.

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.
