Set a Watchman — Isaiah 21:6–9
For thus hath the Lord said unto me,
Go, set a watchman; let him declare what he seeth: and when he seeth a troop, horsemen in pairs, a troop of asses, a troop of camels, he shall hearken diligently with much heed.
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.
