Judges 7:5-6

So he brought the men down to the water, and the Lord said to Gideon, Everyone who laps up the water with his tongue as a dog laps it, you shall set by himself, likewise everyone who bows down on his knees to drink. And the number of those who lapped, putting their hand to their mouth, was 300 men, but all the rest of the people bowed down upon their knees to drink water.
