Judges 7
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.
