ויגש: ולא יכול יוסף להתאפק

Joseph could no longer control himself before all his attendants, and he cried out, “Have everyone withdraw from me!” So there was no one else about when Joseph made himself known to his brothers.

ולא יכל יוסף להתאפק לכל הנצבים AND JOSEPH COULD NOT REFRAIN HIMSELF BEFORE ALL THEM THAT STOOD — He could not bear that the Egyptians should stand by him witnessing how his brothers would be put to shame when he made himself known to them.

REFRAIN HIMSELF. Le-hitappek (refrain himself) means to bear.

THEN JOSEPH COULD NOT ‘L’HITHAPEIK’ (REFRAIN HIMSELF) BEFORE ALL THEM THAT STOOD BY HIM. He could not bear that the Egyptians should stand by him witnessing how his brothers would be put to shame when he makes himself known to them. This is the language of Rashi. But Rabbi Abraham ibn Ezra said that l’hithapeik means “to bear.” The expression Before all them that stood by him, means until all that stood by him would go out, and so it was necessary that he call out that they be removed. Onkelos, however, translated l’hithapeik as meaning “to strengthen himself.” Similarly: ‘Va’ethapak” (And I forced myself) and offered the burnt-offering. Every other form of hithapkuth in every place is likewise an expression of strengthening.
The correct interpretation in my opinion is that there were present many people of Pharaoh’s house and other Egyptians, pleading with Joseph to pardon Benjamin, for their compassions were deeply stirred by Judah’s pleas, and Joseph could not overcome them all. He then called forth to his servants, “Let every strange man go out from me, because I will speak to them.” And when they had gone out, he wept aloud; and the Egyptians heard, and the people of the house of Pharaoh, who had been expelled from his presence, for they were still in the outer court.
It is possible that the expression, ‘hanitzavim’ (them that stood) by him, means his servants who stood before him, just as: The servant ‘hanitzav’ (that was set) over the reapers; ‘sarei hanitzavim’ (chief officers); ‘L’hithyatzeiv’ (To present themselves) before the Eternal. And the meaning of Vayikra (and he called) is that he raised his voice with anger and said to his servants, “Cause every man to go out from before me, except these men.” And the reason for the removal is that he expelled them from there so that they should not hear when he mentions the matter of the sale to his brothers because it would be a source of distress to them and also to himself, for the servants of Pharaoh and the Egyptians will say of them: “These are treacheous people who must not live in our land, nor tread in our palaces. They have acted treacherously against their brother, and also dealt treacherously with their father. What will they do to the king and his people?” They would also no longer believe in Joseph.

R. Samuel the son of Nahman remarked: Then Joseph placed himself in an extremely precarious position, for if his brothers had killed him, not a single person would have been aware of it. Why did he say: Cause every man to go out from me (Gen. 45:1)? Joseph had said to himself: “I would rather die than shame my brothers before the Egyptians.”
