Isaiah 5:26-28

He will also lift up a standard to the distant nation, And will whistle for it from the ends of the earth; And behold, it will come with speed swiftly. No one in it is weary or stumbles, None slumbers or sleeps; Nor is the belt at its waist undone, Nor its sandal strap broken. Its arrows are sharp and all its bows are bent; The hoofs of its horses seem like flint and its chariot wheels like a whirlwind.
