Judges 20:12-21

12And the tribes of Israel sent men through all the tribe of Benjamin, saying, What wickedness is this that is done among you? 13Now therefore deliver us the men, the perverted men, who are in Gibeah, that we may put them to death, and remove the evil from Israel. But the children of Benjamin would not hearken to the voice of their brethren the children of Israel: 14But the children of Benjamin gathered themselves together out of the cities to Gibeah, to go out to battle against the children of Israel. 15And the children of Benjamin were numbered at that time out of the cities twenty and six thousand men that drew sword, besides the inhabitants of Gibeah, who were numbered seven hundred chosen men. 16Among all this people there were seven hundred chosen men lefthanded; every one could sling stones at an hair breadth, and not miss. 17And the men of Israel, besides Benjamin, were numbered four hundred thousand men that drew sword: all these were men of war.

18And the children of Israel arose, and went up to the house of God, and asked counsel of God, and said, Which of us shall go up first to the battle against the children of Benjamin? And the LORD said, Judah shall go up first. 19And the children of Israel rose in the morning, and encamped against Gibeah. 20And the men of Israel went out to battle against Benjamin; and the men of Israel put themselves in array to fight against them at Gibeah. 21And the children of Benjamin came forth from Gibeah, and destroyed down to the ground of the Israelites that day twenty and two thousand men.
