COMMENTARY on 12:78
A. Yusuf Ali:

Translation:
They said: "O exalted one! 1750 Behold! he has a father, aged and venerable, (who will grieve for him); so take one of us in his place; for we seest that you are (gracious) in doing good."
Commentary:

1750  I have translated the tide of 'Aziz here as "the exalted one" when addressed to Joseph in order not to cause confusion with the other man, the 'Aziz, the Courtier, who had bought Joseph on arrival in Egypt . See 12:30 above, and notes 1677 and 1714. (R).
