Isaiah 5:26-29 NIV

[26] 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! [27] 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. [28] Their arrows are sharp, all their bows are strung; their horses’ hooves seem like flint, their chariot wheels like a whirlwind. [29] Their roar is like that of the lion, they roar like young lions; they growl as they seize their prey and carry it off with no one to rescue.
