Isaiah 21:4-9

4My heart staggers; horror has appalled me; the twilight I longed for has been turned for me into trembling.

5They prepare the table, they spread the rugs, they eat, they drink. Arise, O princes; oil the shield!

6For thus the Lord said to me: "Go, set a watchman; let him announce what he sees.

7When he sees riders, horsemen in pairs, riders on donkeys, riders on camels, let him listen diligently, very diligently."

8Then he who saw cried out: "Upon a watchtower I stand, O Lord, continually by day, and at my post I am stationed whole nights.

9And behold, here come riders, horsemen in pairs!" And he answered, "Fallen, fallen is Babylon; and all the carved images of her gods he has shattered to the ground."
