And Joseph took an oath of the children of Israel, saying, {h} God will surely visit you, and ye shall carry up my bones from hence.

(h) He speaks this by the spirit of prophecy, exhorting his brethren to have full trust in God's promise for their deliverance.

Wesley's Notes

50:25 And ye shall carry up my bones from hence - Herein he had an eye to the promise, Gen 15:13,14, and in God's name assures them of the performance of it. In Egypt they buried their great men very honourably, and with abundance of pomp; but Joseph prefers a plain burial in Canaan, and that deferred almost two hundred 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.

Matthew Henry's Concise Commentary

50:22-26 Joseph having honoured his father, his days were long in the land, which, for the present, God had given him. When he saw his death approaching, he comforted his brethren with the assurance of their return to Canaan in due time. We must comfort others with the same comforts with which we have been comforted of God, and encourage them to rest on the promises which are our support. For a confession of his own faith, and a confirmation of theirs, he charges them to keep his remains unburied till that glorious day, when they should be settled in the land of promise. Thus Joseph, by faith in the doctrine of the resurrection, and the promise of Canaan, gave commandment concerning his bones. This would keep up their expectation of a speedy departure from Egypt, and keep Canaan continually in their minds. This would also attach Joseph's posterity to their brethren. The death, as well as the life of this eminent saint, was truly excellent; both furnish us with strong encouragement to persevere in the service of God. How happy to set our early in the heavenly race, to continue stedfastly, and to finish the course with joy! This Joseph did, this we also may do. Even when the pains of death are upon us, if we have trusted in Him upon whom the patriarchs, prophets, and apostles depended, we need not fear to say, My flesh and my heart faileth, but God is the strength of my heart, and my portion for ever.
