Isaiah 5:26-28

He lifts up a banner for the distant nations, he whistles for those at the ends of the earth. Here they come, swiftly and speedily! Not one of them grows tired or stumbles, not one slumbers or sleeps; not a belt is loosened at the waist, not a sandal strap is broken. Their arrows are sharp, all their bows are strung; their horses’ hooves seem like flint, their chariot wheels like a whirlwind.
