Judges 20:23-25 King James Version (KJV)
23 (And the children of Israel went up and wept before the Lord until even, and asked counsel of the Lord, saying, Shall I go up again to battle against the children of Benjamin my brother? And the Lord said, Go up against him.)
24 And the children of Israel came near against the children of Benjamin the second day.
25 And Benjamin went forth against them out of Gibeah the second day, and destroyed down to the ground of the children of Israel again eighteen thousand men; all these drew the sword.
