Judges 7:1-5

Then Jerubbaal (that is, Gideon) and all the people who were with him got up early and camped beside the spring of Harod; and the camp of Midian was north of them by the hill of Moreh in the valley. Then the LORD said to Gideon, “There are too many people with you for Me to hand over Midian to them, otherwise Israel will boast [about themselves] against Me, saying, ‘My own power has rescued me.’ So now, proclaim in the hearing of the people, ‘Whoever is afraid and trembling, let him turn back and leave Mount Gilead.’ ” So twenty-two thousand men returned [home], but ten thousand remained. Then the LORD said to Gideon, “There are still too many people; bring them down to the water and I will test them for you there. Therefore it shall be that he of whom I say to you, ‘This one shall go with you,’ he shall go with you; but everyone of whom I say to you, ‘This one shall not go with you,’ he shall not go.” So he brought the people down to the water, and the LORD said to Gideon, “You shall separate everyone who laps the water with his tongue as a dog laps, as well as everyone who kneels down to drink.”
