Judges 20:25, 35, 46-47

Benjamin went out against them from Gibeah the second day and felled to the ground again 18,000 men of the sons of Israel; all these drew the sword.

And the LORD struck Benjamin before Israel, so that the sons of Israel destroyed 25,100 men of Benjamin that day, all who draw the sword.

So all of Benjamin who fell that day were 25,000 men who draw the sword; all these were valiant warriors. But 600 men turned and fled toward the wilderness to the rock of Rimmon, and they remained at the rock of Rimmon four months.
