Judges 7:19

Middle watch — That is, of the second watch; for though afterward the night was divided into four watches by the Romans, Matthew 14:25, yet in more ancient times, and in the eastern parts, it was divided into three: he chose the dark and dead of the night, to increase their terror by the trumpets, whose sound would then be loudest, and the lamps, whose light would then shine most brightly, to surprise them, and conceal the smallness of their numbers.
