Judges 20:20-22 (NKJV)
[20] And the men of Israel went out to battle against Benjamin, and the men of Israel put themselves in battle array to fight against them at Gibeah.
[21] Then the children of Benjamin came out of Gibeah, and on that day cut down to the ground twenty-two thousand men of the Israelites.
[22] And the people, that is, the men of Israel, encouraged themselves and again formed the battle line at the place where they had put themselves in array on the first day.
