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.Send one of you, and let him fetch your brother,.... He proposes that one of them might be sent by them to their father's house, and bring, Benjamin down to Egypt:

and ye shall be kept in prison; the rest of them till he came:

that your words may be proved, whether there be any truth in you; by this it would be seen whether they were men of truth and honesty or not; and should their brother be brought they would appear to be good men and true:

or else, by the life of Pharaoh, surely ye are spies; should not their brother they spoke of be produced, it would be a plain case that they were not the honest men they pretended to be, nor did they come merely to buy corn, but had an ill intention.
