Genesis 45:1-3

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.
