Isaiah 21:5-7

Amplified Bible

⁵ 
They set the table [for the doomed banquet], they spread out the cloth, they eat, they drink;
“Rise up, captains [of Belshazzar’s court], oil your shields [for battle, for your enemy is at the gates]!”

“Go, station the lookout, let him report what he sees.
⁷ 
“When he sees a chariot, horsemen in pairs,
A train of donkeys and a train of camels,
Let him pay attention and listen closely, very closely.”
