7 Joseph saw his brothers, and he recognized them, but acted like a stranger to them, and spoke roughly with them. He said to them, “Where did you come from?”

They said, “From the land of Canaan to buy food.” 8 Joseph recognized his brothers, but they didn’t recognize him. 9 Joseph remembered the dreams which he dreamed about them, and said to them, “You are spies! You have come to see the nakedness of the land.” 10 They said to him, “No, my lord, but your servants have come to buy food. 11 We are all one man’s sons; we are honest men. Your servants are not spies.” 12 He said to them, “No, but you have come to see the nakedness of the land!” 13 They said, “We, your servants, are twelve brothers, the sons of one man in the land of Canaan; and behold, the youngest is this day with our father, and one is no more.” 14 Joseph said to them, “It is like I told you, saying, ‘You are spies!’ 15 By this you shall be tested. By the life of Pharaoh, you shall not go forth from here, unless your youngest brother comes here. 16 Send one of you, and let him get your brother, and you shall be bound, that your words may be tested, whether there is truth in you, or else by the life of Pharaoh surely you are spies.” 17 He put them all together into custody for three days. 18 Joseph said to them the third day, “Do this, and live, for I fear God. 19 If you are honest men, then let one of your brothers be bound in your prison; but you go, carry grain for the famine of your houses. 20 Bring your youngest brother to me; so will your words be verified, and you won’t die.”

They did 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.
