Here is, I. The prolonging of Joseph's life in Egypt: he lived to be a hundred and ten years old, Gen 50:22. Having honoured his father, his days were long in the land which, for the present, God had given him; and it was a great mercy to his relations that God continued him so long, a support and comfort to them.
II. The building up of Joseph's family: he lived to see his great-grand-children by both his sons (Gen 50:23), and probably he saw his two sons solemnly owned as heads of distinct tribes, equal to any of his brethren. It contributes much to the comfort of aged parents if they see their posterity in a flourishing condition, especially if with it they see peace upon Israel, Psa 128:6.
III. The last will and testament of Joseph published in the presence of his brethren, when he saw his death approaching. Those that were properly his brethren perhaps were some of them dead before him, as several of them were older than he; but to those of them who yet survived, and to the sons of those who were gone, who stood up in their fathers' stead, he said this. 1. He comforted them with the assurance of their return to Canaan in due time: I die, but God will surely visit you, Gen 50:24. To this purport Jacob had spoken to him, Gen 48:21. Thus must we comfort others with the same comforts with which we ourselves have been comforted of God, and encourage them to rest on those promises which have been our support. Joseph was, under God, both the protector and the benefactor of his brethren; and what would become of them now that he was dying? Why, let this be their comfort, God will surely visit you. Note, God's gracious visits will serve to make up the loss of our best friends. They die; but we may live, and live comfortably, if we have the favour and presence of God with us. He bids them be confident: God will bring you out of this land, and therefore, (1.) They must not hope to settle there, nor look upon it as their rest for ever; they must set their hearts upon the land of promise, and call that their home. (2.) They must not fear sinking, and being ruined there; probably he foresaw the ill usage they would meet with there after his death, and therefore gives them this word of encouragement: "God will bring you in triumph out of this land at last." Herein he has an eye to the promise, Gen 15:13, Gen 15:14, and, in God's name, assures them of the performance of it. 2. For a confession of his own faith, and a confirmation of theirs, he charges them to keep him unburied till that day, that glorious day, should come, when they should be settled in the land of promise, v. 25. He makes them promise him with an oath that they would bury him in Canaan. In Egypt they buried their great men very honourably and with abundance of pomp; but Joseph prefers a significant burial in Canaan, and that deferred too almost 200 years, before a magnificent one in Egypt. Thus Joseph, by faith in the doctrine of the resurrection and the promise of Canaan, gave commandment concerning his bones, Heb 11:22. He dies in Egypt; but lays his bones at stake that God will surely visit Israel, and bring them to Canaan.
IV. The death of Joseph, and the reservation of his body for a burial in Canaan, Gen 50:26. He was put in a coffin in Egypt, but not buried till his children had received their inheritance in Canaan, Jos 24:32. Note, 1. If the separate soul, at death, do but return to its rest with God, the matter is not great though the deserted body find not at all, or not quickly, its rest in the grave. 2. Yet care ought to be taken of the dead bodies of the saints, in the belief of their resurrection; for there is a covenant with the dust, which shall be remembered, and a commandment is given concerning the bones.

Joseph said - I die - That is, I am dying; and God will surely visit you - he will yet again give you, in the time when it shall be essentially necessary, the most signal proof of his unbounded love towards the seed of Jacob.
And bring you out of this land - Though ye have here every thing that can render life comfortable, yet this is not the typical land, the land given by covenant, the land which represents the rest that remains for the people of God.

And Joseph took an oath of the children of Israel,.... Not of his brethren only, but of their posterity, as many of them as were now grown up, that so it might be communicated from one to another, and become well known to that generation which should depart out of Egypt:

saying, God will surely visit you; which he repeats for the certainty of it, and that it might be observed:

and ye shall carry up my bones from hence; when they should go from thence to Canaan's land; he did not desire them to carry him thither when he should die, which he knew would give umbrage to the Egyptians, and they would not be so able to obtain leave to do it as he had for his father. This was accordingly done; when Israel went out of Egypt, Moses took the bones of Joseph with him, and they were buried in Shechem; see Exo 13:19.

Joseph said unto his brethren, I die--The national feelings of the Egyptians would have been opposed to his burial in Canaan; but he gave the strongest proof of the strength of his faith and full assurance of the promises, by "the commandment concerning his bones" [Heb 11:22].
