Judges 7:2-8

And Jehovah said unto Gideon, The people that are with thee are too many for me to give the Midianites into their hand, lest Israel vaunt themselves against me, saying, Mine own hand hath saved me. Now therefore proclaim in the ears of the people, saying, Whosoever is fearful and trembling, let him return and depart from mount Gilead. And there returned of the people twenty and two thousand; and there remained ten thousand. And Jehovah said unto Gideon, The people are yet too many; bring them down unto the water, and I will try them for thee there: and it shall be, that of whom I say unto thee, This shall go with thee, the same shall go with thee; and of whomsoever I say unto thee, This shall not go with thee, the same shall not go. 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. And Jehovah said unto Gideon, By the three hundred men that lapped will I save you, and deliver the Midianites into thy hand; and let all the people go every man unto his place. So the people took victuals in their hand, and their trumpets; and he sent all the men of Israel every man unto his tent, but retained the three hundred men: and the camp of Midian was beneath him in the valley.
