Isaiah 21:8

5 They set the tables, they spread the rugs, they eat, they drink! Get up, you officers, oil the shields! 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.
