Judges 20:31-32

31And the children of Benjamin went out against the people, and were drawn away from the city; and they began to smite of the people, and kill, as at other times, in the highways, of which one goeth up to the house of God, and the other to Gibeah in the field, about thirty men of Israel.12 32And the children of Benjamin said, They are smitten down before us, as at the first. But the children of Israel said, Let us flee, and draw them from the city to the highways.
