The day of the battle, the army from the descendants of Benjamin numbered 26,000 expert swordsmen from their cities, not including the inhabitants of Gibeah, who numbered 700 special forces soldiers.

But the Israeli army not counting the tribe of Benjamin numbered 400,000 expert swordsmen, all of them battle-hardened soldiers.

and the tribe of Benjamin went to war against them from Gibeah during that second day, and 18,000 soldiers from the Israelis all of them expert swordsmen fell to the ground.

The LORD struck Benjamin in the full view of Israel. As a result, the Israelis destroyed 25,100 soldiers of Benjamin that day, all expert swordsmen.

To sum up, the soldiers from the tribe of Benjamin who died that day totaled 25,000 men, all of them expert swordsmen and valiant soldiers.
