Judges 7:2-7

2And Jehovah said to Gideon, The people that are with thee are too many for me to give Midian into their hand, lest Israel vaunt themselves against me, saying, Mine own hand hath saved me.

3And now proclaim in the ears of the people, saying, Whoever is timid and afraid, let him go back and turn from mount Gilead. And there went back of the people twenty-two thousand; and there remained ten thousand.

4And Jehovah said to Gideon, Still the people are many; bring them down to the water, and I will try them for thee there, and it shall be, that of whom I shall say unto thee, This shall go with thee, the same shall go with thee; and of whomsoever I shall say unto thee, This shall not go with thee, the same shall not go.

5And he brought down the people to the water; and Jehovah said to 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 on his knees to drink.

6And the number of them that lapped, with their hand to their mouth, were three hundred men; and all the rest of the people bowed down on their knees to drink water.

7And Jehovah said to Gideon, By the three hundred men that lapped will I save you, and give Midian into thy hand; and let all the people go every man to his place.
