Judges 20:34-36

Amplified Bible

³⁴ When the ten thousand choice [fighting] men from all Israel came against Gibeah, the battle was hard and fierce; but the Benjamites did not realize that disaster was about to strike them. ³⁵ And the Lord struck down [the tribe of] Benjamin before Israel, so that the sons of Israel destroyed twenty-five thousand one hundred men of Benjamin that day, all of whom were swordsmen.

³⁶ So the Benjamites realized that they were defeated. Then men of Israel gave ground to the Benjamites, because they relied on the men in ambush whom they had placed against Gibeah.
