Judges 20:25, 35, 46-47

And Benjamin went forth against them out of Gibeah the second day, and destroyed down to the ground of the children of Israel again eighteen thousand men; all these drew the sword.

And the LORD smote Benjamin before Israel: and the children of Israel destroyed of the Benjamites that day twenty and five thousand and an hundred men: all these drew the sword.

So that all which fell that day of Benjamin were twenty and five thousand men that drew the sword; all these were men of valour. But six hundred men turned and fled to the wilderness unto the rock Rimmon, and abode in the rock Rimmon four months.
