Judges 7:4-6

New King James Version

⁴ 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.” ⁵ 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.” ⁶ 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.
