Read Genesis 45:1 Using Other Translations
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.
Then Joseph could not control himself before all those who stood by him. He cried, "Make everyone go out from me." So no one stayed with him when Joseph made himself known to his brothers.
Joseph could stand it no longer. There were many people in the room, and he said to his attendants, “Out, all of you!” So he was alone with his brothers when he told them who he was.
