Isaiah 21:8 ASV

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.

¹⁰  O thou my threshing, and the grain of my floor! that which I have heard from Jehovah of hosts, the God of Israel, have I declared unto you.
