Judges 7:2-12

2 And the Lord said to Gedeon, The people with thee many, so that I may not deliver Madiam into their hand, lest at any time Israel boast against me, saying, My hand has saved me.
3 And now speak in the ears of the people, saying, Who afraid and fearful? let him turn and depart from mount Galaad: and there returned of the people twenty-two thousand, and ten thousand were left.
4 And the Lord said to Gedeon, The people is yet numerous; bring them down to the water, and I will purge them there for thee: and it shall come to pass that of whomsoever I shall say to thee, This one shall go with thee, he shall go with thee; and of whomsoever I shall say to thee, This one shall not go with thee, he shall not go with thee.
5 And he brought the people down to the water; and the Lord said to Gedeon, Whosoever shall lap of the water with his tongue as if a dog should lap, thou shalt set him apart, and whosoever shall bow down upon his knees to drink.
6 And the number of those that lapped with their hand to their mouth was three hundred men; and all the rest of the people bowed upon their knees to drink water.
7 And the Lord said to Gedeon, I will save you by the three hundred men that lapped, and I will give Madiam into thy hand; and all the people shall go every one to his place.
8 And they took the provision of the people in their hand, and their horns; and he sent away every man of Israel each to his tent, and he strengthened the three hundred; and the army of Madiam were beneath him in the valley.
9 And it came to pass in that night that the Lord said to him, Arise, go down into the camp, for I have delivered it into thy hand.
10 And if thou art afraid to go down, go down thou and thy servant Phara into the camp.
11 And thou shalt hear what they shall say, and afterwards thy hands shall be strong, and thou shalt go down into the camp: and he went down and Phara his servant to the extremity of the fifty, which were in the camp.
12 And Madiam and Amalec and all the children of the east scattered in the valley, as the locust for multitude; and there was no number to their camels, but they were as the sand on the seashore for multitude.
