John Calvin Commentary Genesis 50:22

"And Joseph dwelt in Egypt, he, and his father`s house: and Joseph lived a hundred and ten years." — Genesis 50:22 (ASV)

And Joseph dwelt in Egypt. It is not without reason that Moses relates how long Joseph lived, because the length of the time shows more clearly his unfailing constancy: for although he is raised to great honor and power among the Egyptians, he still is closely united with his father’s house.

Hence it is easy to conjecture that he gradually took his leave of the treasures of the court, because he thought there was nothing better for him to do than to hold them in contempt, for fear that earthly dignity might separate him from the kingdom of God. He had before spurned all the allurements which might have occupied his mind in Egypt: he now counts it necessary to proceed further, that, laying aside his honor, he may descend to an ignoble condition and wean his own sons from the hope of succeeding to his worldly rank.

We know how anxiously others labor, both that they themselves may not be reduced in circumstances, and that they may leave their fortune entire to their posterity: but Joseph, during sixty years, employed all his efforts to bring himself and his children into a state of submission, for fear that his earthly greatness might alienate them from the little flock of the Lord.

In short, he imitated the serpents, who cast off their exuviae, that, being stripped of their old age, they may gather new strength.

He sees the children of his own grandchildren; why does his solicitude to provide for them not increase, as his children increase? Yet he has so little regard for worldly rank or opulence, that he would rather see them devoted to a pastoral life, and be despised by the Egyptians, if only they might be reckoned in the family of Israel.

Besides, in a numerous offspring during his own life, the Lord afforded him some taste of his benediction, from which he might conceive the hope of future deliverance: for, among so many temptations, it was necessary for him to be encouraged and sustained, for fear that he might sink under them.
