Isaiah 21:7-9

7When he sees a chariot with a pair of horsemen, riders on donkeys, riders on camels, let him pay attention— very close attention!”

8Then he cried out like a lion: “Upon the watch tower, Adonai, I stand continually in the daytime, and stay at my post every night.

9Look! Here comes a chariot of men, with a pair of horsemen.” Then one answered and said, “Fallen, fallen is Babylon! All the images of her gods are broken on the ground.”
