Isaiah 21:6-10 NIV

[6] This is what the Lord says to me: “Go, post a lookout and have him report what he sees. [7] When he sees chariots with teams of horses, riders on donkeys or riders on camels, let him be alert, fully alert.” [8] And the lookout shouted, “Day after day, my lord, I stand on the watchtower; every night I stay at my post. [9] Look, here comes a man in a chariot with a team of horses. And he gives back the answer: ‘Babylon has fallen, has fallen! All the images of its gods lie shattered on the ground!’ ” [10] My people who are crushed on the threshing floor, I tell you what I have heard from the LORD Almighty, from the God of Israel.
