7 When Joseph saw his brothers, he recognized them, but he treated them like strangers and spoke harshly to them. "Where do you come from?" he said. They said, "From the land of Canaan, to buy food." 8 Although Joseph had recognized his brothers, they did not recognize him. 9 Joseph also remembered the dreams that he had dreamed about them. He said to them, "You are spies; you have come to see the nakedness of the land!" 10 They said to him, "No, my lord; your servants have come to buy food. 11 We are all sons of one man; we are honest men; your servants have never been spies." 12 But he said to them, "No, you have come to see the nakedness of the land!" 13 They said, "We, your servants, are twelve brothers, the sons of a certain man in the land of Canaan; the youngest, however, is now with our father, and one is no more." 14 But Joseph said to them, "It is just as I have said to you; you are spies! 15 Here is how you shall be tested: as Pharaoh lives, you shall not leave this place unless your youngest brother comes here! 16 Let one of you go and bring your brother, while the rest of you remain in prison, in order that your words may be tested, whether there is truth in you; or else, as Pharaoh lives, surely you are spies." 17 And he put them all together in prison for three days. 18 On the third day Joseph said to them, "Do this and you will live, for I fear God: 19 if you are honest men, let one of your brothers stay here where you are imprisoned. The rest of you shall go and carry grain for the famine of your households, 20 and bring your youngest brother to me. Thus your words will be verified, and you shall not die." And they agreed to do so.

Commentary on Genesis 42:7-20

(Read Genesis 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.
