Isaiah 21:5-15

5 They set the table, light the lamps, eat and drink - "Get going, princes! Oil the shields!"
6 For this is what Adonai said to me: "Go, post a watchman to report what he sees!
7 If he sees the cavalry, horsemen in pairs, riders on donkeys, riders on camels, he must be on alert, on full alert!"
8 He calls out like a lion: "My lord, I stand on the watchtower all day long, I stay at my post all night."
9 Then, as they appeared - the cavalry, horsemen in pairs - he spoke these words: "She has fallen! She has fallen - Bavel! All the carved images of her gods lie shattered on the ground."
10 My people, who have been threshed, grain trodden down on my threshing-floor: I am telling you what I have heard from ADONAI-Tzva'ot, the God of Isra'el.
11 A prophecy about Dumah: Someone is calling to me from Se'ir: "Watchman, how much longer is it night? Watchman, how much longer is it night?"
12 The watchman answers: "Morning is coming, but also the night. If you want to ask, ask! Come back again!"
13 A prophecy about Arabia: You caravans of D'danim will camp in the desert growth of Arabia.
14 Bring water to the thirsty, you who live in Teima, greet the fugitives with food;
15 because they are fleeing the sword, the drawn sword, the bent bow and the press of battle.
