Isaiah 21:7-9

Revised Standard Version Catholic Edition

⁷ When he sees riders, horsemen in pairs,
    riders on asses, riders on camels,
let him listen diligently,
    very diligently.”
⁸ Then he who saw^[a] cried:
“Upon a watchtower I stand, O Lord,
    continually by day,
and at my post I am stationed
    whole nights.
⁹ And behold, here come riders,
    horsemen in pairs!”
And he answered,
    “Fallen, fallen is Babylon;
and all the images of her gods
    he has shattered to the ground.”
