Giv Keeps Watch over the Sleepers

From B10.20, Kay Khosrow, Giv, and Farangis Flee to Iran. It illustrates B10.20.17–21:

B10.20.17
Meanwhile Khosrow and Farangis both lay,Exhausted from their long and weary way.
B10.20.18
The road was long, the night had brought them strain;So Giv stood guardian while the two had lain.
B10.20.19
While both lay sleeping, Giv stayed wide awake,His eyes fixed on the road that riders take.
B10.20.20
His horse in bargostvan stood battle-dressed,Prepared for war at his rider’s behest.
B10.20.21
In jowshan, helmet, Giv stood fierce and dread,His body pledged to death, all terror shed.
