Isaiah 5:25-28

25Therefore the Lord’s anger burns against his people; his hand is raised and he strikes them down. The mountains shake, and the dead bodies are like refuse in the streets. Yet for all this, his anger is not turned away, his hand is still upraised. 26He lifts up a banner for the distant nations, he whistles for those at the ends of the earth. Here they come, swiftly and speedily! 27Not 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. 28Their arrows are sharp, all their bows are strung; their horses’ hooves seem like flint, their chariot wheels like a whirlwind.
