From B8.10, Gazhdaham’s Letter to Kavus. It illustrates B8.10.29–32:

B8.10.29
At night he sealed the letter he had penned,And called a trusted rider at the end.
B8.10.30
He gave the sealed dispatch, and bade him heed:“Ride hard and do precisely what I need.
B8.10.31
Before the dawn, be hidden from their sight;Let none among that army mark your flight.”

The rider bound the letter at his side,Then rose at once and swiftly left to ride.
