Judges 7:1-3

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.
