Genesis 45:1-3

1Then Joseph could no longer control himself before all his attendants, and he cried out, “Send everyone away from me!”

So none of them were with Joseph when he made himself known to his brothers. 2But he wept so loudly that the Egyptians heard him, and Pharaoh’s household soon heard of it.

3Joseph said to his brothers, “I am Joseph! Is my father still alive?”

But they were unable to answer him, because they were terrified in his presence.
