Judges 7:1-9

1 And Jerobaal rose early, the same is Gedeon, and all the people with him, and encamped at the fountain of Arad; and the camp of Madiam was to the north of him, from Gabaathamorai, in the valley.
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.
