Genesis 42:10 - Paying Homage to Joseph

And they said unto him, Nay, my lord, but to buy food are thy servants come.

Does Joseph indeed reign over his brothers (Genesis 37:8)? my lord: Is an expression of respect and reverence to one who has dominion over the affairs of state. thy servants: Is an expression of submission to one in authority. Therefore the answer to the question is yes; for Joseph has the absolute dominion over all who are in need of corn, including his brothers.
