Judges 7:5-6
Judges 7:5-6 ASV
So he brought down the people unto the water: and Jehovah said unto Gideon, Every one that lappeth of the water with his tongue, as a dog lappeth, him shalt thou set by himself; likewise every one that boweth down upon his knees to drink. And the number of them that lapped, putting their hand to their mouth, was three hundred men: but all the rest of the people bowed down upon their knees to drink water.
