And they said unto him, nay, my lord,.... One in the name of the rest, or each in his turn, denying that they were spies, and addressing him with the greatest reverence and submission, calling him their lord, and thus further accomplishing his dreams:

but to buy food are thy servants come; that and no other was the errand they came upon.

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

42:7-20 Joseph was hard upon his brethren, not from a spirit of revenge, but to bring them to repentance. Not seeing his brother Benjamin, he suspected that they had made away with him, and he gave them occasion to speak of their father and brother. God, in his providence, sometimes seems harsh with those he loves, and speaks roughly to those for whom yet he has great mercy in store. Joseph settled at last, that one of them should be left, and the rest go home and fetch Benjamin. It was a very encouraging word he said to them, I fear God; as if he had said, You may be assured I will do you no wrong; I dare not, for I know there is one higher than I. With those that fear God, we may expect fair dealing.
