Isaiah 21:8

"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; 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."

Here is the same language employed by the Lord through the apostle John in describing the fall of the Great Harlot of the times of the Apostasy (Revelation 14:8; 17:5). It is this fact, more than any other, which supports the view that there could be a great deal more in this passage than a prophecy of one of the several falls of ancient Babylon. Babylon became, in time, a symbol of all wickedness and unrighteousness, giving her name to the Great Apostasy itself.
