Judges 7:1-8

So Jerub-baal (that is, Gideon) and his army got up early and went as far as the spring of Harod. The armies of Midian were camped north of them in the valley near the hill of Moreh. The LORD said to Gideon, “You have too many warriors with you. If I let all of you fight the Midianites, the Israelites will boast to me that they saved themselves by their own strength. Therefore, tell the people, ‘Whoever is timid or afraid may leave this mountain and go home.’” So 22,000 of them went home, leaving only 10,000 who were willing to fight. But the LORD told Gideon, “There are still too many! Bring them down to the spring, and I will test them to determine who will go with you and who will not.” When Gideon took his warriors down to the water, the LORD told him, “Divide the men into two groups. In one group put all those who cup water in their hands and lap it up with their tongues like dogs. In the other group put all those who kneel down and drink with their mouths in the stream.” Only 300 of the men drank from their hands. All the others got down on their knees and drank with their mouths in the stream. The LORD told Gideon, “With these 300 men I will rescue you and give you victory over the Midianites. Send all the others home.” So Gideon collected the provisions and rams’ horns of the other warriors and sent them home. But he kept the 300 men with him. The Midianite camp was in the valley just below Gideon.
