Judges 20:34-36

And there came against Gibeah 10,000 chosen men out of all Israel, and the battle was hard, but the Benjaminites did not know that disaster was close upon them. And the LORD defeated Benjamin before Israel, and the people of Israel destroyed 25,100 men of Benjamin that day. All these were men who drew the sword. So the people of Benjamin saw that they were defeated. The men of Israel gave ground to Benjamin, because they trusted the men in ambush whom they had set against Gibeah.
