Isaiah 21:8 WEB

⁶  For thus has the Lord said to me, Go, set a watchman: let him declare what he sees:

⁷  and when he sees a troop, horsemen in pairs, a troop of donkeys, a troop of camels, he shall listen diligently with much heed.

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

⁹  and, behold, here comes a troop of men, horsemen in pairs. He answered, Fallen, fallen is Babylon; and all the engraved images of her gods are broken to the ground.

¹⁰  You my threshing, and the grain of my floor! that which I have heard from Yahweh of hosts, the God of Israel, have I declared to you.
