Judges 20:25, 35, 46-47

And Benjamin went against them out of Gibeah the second day, and destroyed 18,000 men of the people of Israel. All these were men who drew the sword.

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 all who fell that day of Benjamin were 25,000 men who drew the sword, all of them men of valor. But 600 men turned and fled toward the wilderness to the rock of Rimmon and remained at the rock of Rimmon four months.
