Then Joseph could not refrain himself before all them that stood by him; and he cried, {a} Cause every man to go out from me. And there stood no man with him, while Joseph made himself known unto his brethren.

(a) Not because he was ashamed of his kindred, but rather because he wanted to cover his brother's sin.

Wesley's Notes

45:1 Judah and his brethren were waiting for an answer, and could not but be amazed to discover, instead of the gravity of a judge, the natural affection of a father or brother. [1.] Cause every man to go out - The private conversations of friends are the most free. When Joseph would put on love, he puts off state, which it was not fit his servants should be witnesses of. Thus Christ graciously manifests himself and his loving kindness to his people, out of the sight and hearing of the world. [2.] V.
2. Tears were the introduction to his discourse. He had dammed up this stream a great while, and with much ado, but now it swelled so high that he could no longer contain, but he wept aloud, so that those whom he had forbid to see him could not but hear him. These were tears of tenderness and strong affection, and with these he threw off that austerity, with which he had hitherto carried himself towards his brethren; for he could bear it no longer. This represents the Divine compassion towards returning penitents, as much as that of the father of the prodigal, Luke 15:20 Hos 11:8,9. [3.] V.
3. He abruptly tells them; I am Joseph - They knew him only by his Egyptian name, Zaphnath - paaneah, his Hebrew name being lost and forgot in Egypt; but now he teaches them to call him by that, I am Joseph: nay, that they might not suspect it was another of the same name, he explains himself. I am Joseph your brother. This would both humble them yet more for their sin in selling him, and encourage them to hope for kind treatment. This word, at first, startled Joseph's brethren, they started back through fear, or at least stood still astonished: but Joseph called kindly and familiarly to them. Come near, I pray you. Thus, when Christ manifests himself to his people he encourages them to draw near to him with a true heart. Perhaps being about to speak of their selling of him, he would not speak aloud, lest the Egyptians should overhear, and it should make the Hebrews to be yet more an abomination to them; therefore he would have them come near, that he might whisper with them, which, now the tide of his passion was a little over, he was able to do, whereas, at first, he could not but cry out. [4.] He endeavours to sweep their grief for the injuries they had done him, by shewing them, that, whatever they designed, God meant it for good, and had brought much good out of it.

Jamieson-Fausset-Brown Bible Commentary

CHAPTER 45

Ge 45:1-28. Joseph Making Himself Known.

1. Then Joseph could not refrain himself-The severity of the inflexible magistrate here gives way to the natural feelings of the man and the brother. However well he had disciplined his mind, he felt it impossible to resist the artless eloquence of Judah. He saw a satisfactory proof, in the return of all his brethren on such an occasion, that they were affectionately united to one another; he had heard enough to convince him that time, reflection, or grace had made a happy improvement on their characters; and he would probably have proceeded in a calm and leisurely manner to reveal himself as prudence might have dictated. But when he heard the heroic self-sacrifice of Judah [Ge 44:33] and realized all the affection of that proposal-a proposal for which he was totally unprepared-he was completely unmanned; he felt himself forced to bring this painful trial to an end.

he cried, Cause every man to go out from me-In ordering the departure of witnesses of this last scene, he acted as a warm-hearted and real friend to his brothers-his conduct was dictated by motives of the highest prudence-that of preventing their early iniquities from becoming known either to the members of his household, or among the people of Egypt.

Matthew Henry's Concise Commentary

45:1-15 Joseph let Judah go on, and heard all he had to say. He found his brethren humbled for their sins, mindful of himself, for Judah had mentioned him twice in his speech, respectful to their father, and very tender of their brother Benjamin. Now they were ripe for the comfort he designed, by making himself known. Joseph ordered all his attendants to withdraw. Thus Christ makes himself and his loving-kindness known to his people, out of the sight and hearing of the world. Joseph shed tears of tenderness and strong affection, and with these threw off that austerity with which he had hitherto behaved toward his brethren. This represents the Divine compassion toward returning penitents. I am Joseph, your brother. This would humble them yet more for their sin in selling him, but would encourage them to hope for kind treatment. Thus, when Christ would convince Paul, he said, I am Jesus; and when he would comfort his disciples, he said, It is I, be not afraid. When Christ manifests himself to his people, he encourages them to draw near to him with a true heart. Joseph does so, and shows them, that whatever they thought to do against him, God had brought good out of it. Sinners must grieve and be angry with themselves for their sins, though God brings good out of it, for that is no thanks to them. The agreement between all this, and the case of a sinner, on Christ's manifesting himself to his soul, is very striking. He does not, on this account, think sin a less, but a greater evil; and yet he is so armed against despair, as even to rejoice in what God hath wrought, while he trembles in thinking of the dangers and destruction from which he has escaped. Joseph promises to take care of his father and all the family. It is the duty of children, if the necessity of their parents at any time require it, to support and supply them to the utmost of their ability; this is showing piety at home, 1Ti 5:4. After Joseph had embraced Benjamin, he caressed them all, and then his brethren talked with him freely of all the affairs of their father's house. After the tokens of true reconciliation with the Lord Jesus, sweet communion with him follows.
