Judges 20:34-36

There were 10,000 elite Israelite troops who advanced against Gibeah. The fighting was so heavy that Benjamin didn’t realize the impending disaster. So the LORD helped Israel defeat Benjamin, and that day the Israelites killed 25,100 of Benjamin’s warriors, all of whom were experienced swordsmen. Then the men of Benjamin saw that they were beaten. The Israelites had retreated from Benjamin’s warriors in order to give those hiding in ambush more room to maneuver against Gibeah.
