Joseph breaks down

Genesis 45 Then Joseph could not refrain himself before all them that stood by him; and he cried, Cause every man to go out from me. And there stood no man with him, while Joseph made himself known unto his brethren. 2And he wept aloud: and the Egyptians and the house of Pharaoh heard. 3And Joseph said unto his brethren, I am Joseph; doth my father yet live? And his brethren could not answer him; for they were troubled at his presence. 4And Joseph said unto his brethren, Come near to me, I pray you. And they came near. And he said, I am Joseph your brother, whom ye sold into Egypt.
