Judges 20:12-21

12And the tribes of Israel sent men through all the tribe of Benjamin, saying, What wickedness is this that is come to pass among you? 13Now therefore deliver up the men, the base fellows, that are in Gibeah, that we may put them to death, and put away evil from Israel. But Benjamin would not hearken to the voice of their brethren the children of Israel. 14And the children of Benjamin gathered themselves together out of the cities unto Gibeah, to go out to battle against the children of Israel. 15And the children of Benjamin were numbered on that day 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 a 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 Beth-el, and asked counsel of God; and they said, Who shall go up for us first to battle against the children of Benjamin? And Jehovah said, Judah shall go up first.

19And the children of Israel rose up in the morning, and encamped against Gibeah. 20And the men of Israel went out to battle against Benjamin; and the men of Israel set the battle in array against them at Gibeah. 21And the children of Benjamin came forth out of Gibeah, and destroyed down to the ground of the Israelites on that day twenty and two thousand men.
