Genesis 45:1-7

THEN JOSEPH could not restrain himself [any longer] before all those who stood by him, and he called out, Cause every man to go out from me! So no one stood there with Joseph while he made himself known to his brothers. And he wept and sobbed aloud, and the Egyptians [who had just left him] heard it, and the household of Pharaoh heard about it. And Joseph said to his brothers, I am Joseph! Is my father still alive? And his brothers could not reply, for they were distressingly disturbed and dismayed at [the startling realization that they were in] his presence. And Joseph said to his brothers, Come near to me, I pray you. And they did so. And he said, I am Joseph your brother, whom you sold into Egypt! But now, do not be distressed and disheartened or vexed and angry with yourselves because you sold me here, for God sent me ahead of you to preserve life. For these two years the famine has been in the land, and there are still five years more in which there will be neither plowing nor harvest. God sent me before you to preserve for you a posterity and to continue a remnant on the earth, to save your lives by a great escape and save for you many survivors.
