Isaiah 5:26-28

He will raise a signal for nations far away, and whistle for them from the ends of the earth; and behold, quickly, speedily they come! None is weary, none stumbles, none slumbers or sleeps, not a waistband is loose, not a sandal strap broken; their arrows are sharp, all their bows bent, their horses’ hoofs seem like flint, and their wheels like the whirlwind.
