Isaiah 21:7-9

7When he sees a chariot, horsemen in pairs, A train of donkeys and a train of camels, Let him pay attention and listen closely, very closely.”

8And the lookout called like a lion, “O Lord, I stand continually on the watchtower by day, And I am stationed every night at my guard post.

9Now look! Here comes a troop of riders, horsemen in pairs.” And one said, “Fallen, fallen is Babylon; And all the carved images of her gods are shattered on the ground.”
