Judges 7:2-3

2The Lord said to Gideon, ‘You have too many men in your army. When I put the Midianites under your power, your soldiers may boast about their own strength. They may say that they have won the battle themselves.

3So say to the men, “If you are very afraid of the battle and you are shaking with fear, you may go.” ’ So 22,000 men left that place and they went home. But 10,000 soldiers remained with Gideon.
