Judges 20:13-15
20:13 Now, hand over the good-for-nothings in Gibeah so we can execute them and purge Israel of wickedness.” But the Benjaminites refused to listen to their Israelite brothers.
20:14 The Benjaminites came from their cities and assembled at Gibeah to make war against the Israelites.
20:15 That day the Benjaminites mustered from their cities twenty-six thousand sword-wielding soldiers, besides seven hundred well-trained soldiers from Gibeah.
