Isaiah 21:10

⁸  And he cried, A lion: My lord, I stand continually upon the watchtower in the daytime, and I am set in my ward whole nights:

⁹  And, behold, here cometh a chariot of men, with a couple of horsemen. And he answered and said, Babylon is fallen, is fallen; and all the graven images of her gods he hath broken unto the ground.

¹⁰  O my threshing, and the corn of my floor: that which I have heard of the LORD of hosts, the God of Israel, have I declared unto you.

¹¹  The burden of Dumah. He calleth to me out of Seir, Watchman, what of the night? Watchman, what of the night?

¹²  The watchman said, The morning cometh, and also the night: if ye will enquire, enquire ye: return, come.
