Isaiah 5:27-30

27None of them grows weary or stumbles; no one slumbers or sleeps. No belt is loose and no sandal strap broken.

28Their arrows are sharpened, and all their bows strung. Their horses’ hooves are like flint; their chariot wheels are like a whirlwind.

29Their roaring is like a lion’s; they roar like young lions; they growl and seize their prey and carry it off, and no one can rescue it.

30On that day they will roar over it, like the roaring of the sea. When one looks at the land, there will be darkness and distress; light will be obscured by clouds.
