And Joseph said unto them, that is it that I spake unto you, saying, ye are spies. This proves it, at least gives strong suspicion of it; since at first they seemed to speak of themselves, as if they were the only sons of one man and there were no more, now they speak of twelve, and make mention of one being at home with his father; but seeing he sent so many of them, why not all? why should one only be left at home?

And Joseph said unto them, That is it that I spake unto you, saying, Ye are spies:

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.
