Judges 7:2-3

The LORD said to Gideon, “The people who are with you are too many for Me to give Midian into their hands, for Israel would become boastful, saying, ‘My own power has delivered me.’ Now therefore come, proclaim in the hearing of the people, saying, ‘Whoever is afraid and trembling, let him return and depart from Mount Gilead.’ ” So 22,000 people returned, but 10,000 remained.
