When Joseph saw his brothers he recognized them, but he disguised himself to them and spoke to them harshly. And he said to them, "Where have you come from?" And they said, "From the land of Canaan, to buy food." But Joseph had recognized his brothers, although they did not recognize him. Joseph remembered the dreams which he had about them, and said to them, "You are spies; you have come to look at the undefended parts of our land." read more.
Then they said to him, "No, my lord, but your servants have come to buy food. "We are all sons of one man; we are honest men, your servants are not spies." Yet he said to them, "No, but you have come to look at the undefended parts of our land!" But they said, "Your servants are twelve brothers in all, the sons of one man in the land of Canaan; and behold, the youngest is with our father today, and one is no longer alive." Joseph said to them, "It is as I said to you, you are spies; by this you will be tested: by the life of Pharaoh, you shall not go from this place unless your youngest brother comes here! "Send one of you that he may get your brother, while you remain confined, that your words may be tested, whether there is truth in you. But if not, by the life of Pharaoh, surely you are spies." So he put them all together in prison for three days. Now Joseph said to them on the third day, "Do this and live, for I fear God: if you are honest men, let one of your brothers be confined in your prison; but as for the rest of you, go, carry grain for the famine of your households, and bring your youngest brother to me, so your words may be verified, and you will not die." And they did so.

When Joseph came home, they brought into the house to him the present which was in their hand and bowed to the ground before him. Then he asked them about their welfare, and said, "Is your old father well, of whom you spoke? Is he still alive?" They said, "Your servant our father is well; he is still alive." They bowed down in homage. read more.
As he lifted his eyes and saw his brother Benjamin, his mother's son, he said, "Is this your youngest brother, of whom you spoke to me?" And he said, "May God be gracious to you, my son." Joseph hurried out for he was deeply stirred over his brother, and he sought a place to weep; and he entered his chamber and wept there. Then he washed his face and came out; and he controlled himself and said, "Serve the meal." So they served him by himself, and them by themselves, and the Egyptians who ate with him by themselves, because the Egyptians could not eat bread with the Hebrews, for that is loathsome to the Egyptians. Now they were seated before him, the firstborn according to his birthright and the youngest according to his youth, and the men looked at one another in astonishment. He took portions to them from his own table, but Benjamin's portion was five times as much as any of theirs. So they feasted and drank freely with him.
