Genesis 45:1-7

Then Joseph could not control himself [any longer] in front of all those who attended him, and he called out, “Have everyone leave me.” So no man stood there when Joseph revealed himself to his brothers. Joseph wept aloud, and the Egyptians [who had just left him] heard it, and the household of Pharaoh heard of it. Then Joseph said to his brothers, “I am Joseph! Is my father still alive?” But his brothers were speechless, for they were stunned and dismayed by [the fact that they were in] Joseph’s presence. And Joseph said to his brothers, “Please come closer to me.” And they approached him. And he said, “I am Joseph your brother, whom you sold into Egypt. Now do not be distressed or angry with yourselves because you sold me here, for God sent me ahead of you to save life and preserve our family. For the famine has been in the land these two years, and there are still five more years in which there will be no plowing and harvesting. God sent me [to Egypt] ahead of you to preserve for you a remnant on the earth, and to keep you alive by a great escape.
