Judges 7:4-11

But the LORD said to Gideon, “The people are still too many; bring them down to the water, and I will test them for you there. Then it will be, that of whom I say to you, ‘This one shall go with you,’ the same shall go with you; and of whomever I say to you, ‘This one shall not go with you,’ the same shall not go.” So he brought the people down to the water. And the LORD said to Gideon, “Everyone who laps from the water with his tongue, as a dog laps, you shall set apart by himself; likewise everyone who gets down on his knees to drink.” And the number of those who lapped, putting their hand to their mouth, was three hundred men; but all the rest of the people got down on their knees to drink water. Then the LORD said to Gideon, “By the three hundred men who lapped I will save you, and deliver the Midianites into your hand. Let all the other people go, every man to his place.” So the people took provisions and their trumpets in their hands. And he sent away all the rest of Israel, every man to his tent, and retained those three hundred men. Now the camp of Midian was below him in the valley. It happened on the same night that the LORD said to him, “Arise, go down against the camp, for I have delivered it into your hand. But if you are afraid to go down, go down to the camp with Purah your servant, and you shall hear what they say; and afterward your hands shall be strengthened to go down against the camp.” Then he went down with Purah his servant to the outpost of the armed men who were in the camp.
