Judges 7
4 Ref Yahweh said to Gideon, The people are yet too many; bring them down to the water, and I will try them for you there: and it shall be, that of whom I tell you, This shall go with you, the same shall go with you; and of whoever I tell you, This shall not go with you, the same shall not go.
5 So he brought down the people to the water: and Yahweh said to Gideon, Everyone who laps of the water with his tongue, as a dog laps, him shall you set by himself; likewise everyone who bows down on his knees to drink.
6 The number of those who lapped, putting their hand to their mouth, was three hundred men: but all the rest of the people bowed down on their knees to drink water.
7 Ref Yahweh said to Gideon, By the three hundred men who lapped will I save you, and deliver the Midianites into your hand; and let all the people go every man to his place.
