Isaiah 21:6-9

MLV(i) 6 For thus has the Lord said to me, Go, set a watchman. Let him declare what he sees. 7 and when he sees a troop, horsemen in pairs, a troop of donkeys, a troop of camels, he will listen diligently with much heed.
8 And he cried out as a lion, O Lord, I stand continually upon the watchtower in the daytime and am set in my confinement whole nights, 9 and behold, here comes a troop of men, horsemen in pairs. And he answered and said, Fallen, fallen is Babylon. And all the graven images of her gods are broken to the ground.
