Isaiah 21:7 ASV

⁵  They prepare the table, they set the watch, they eat, they drink: rise up, ye princes, anoint the shield.

⁶  For thus hath the Lord said unto me, Go, set a watchman: let him declare what he seeth:

⁷  and when he seeth a troop, horsemen in pairs, a troop of asses, a troop of camels, he shall hearken diligently with much heed.

⁸  And he cried as a lion: O Lord, I stand continually upon the watch-tower in the day-time, and am set in my ward whole nights;

⁹  and, behold, here cometh 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 unto the ground.
