John Calvin on Genesis 47:28

28. And Jacob lived. It was no common source of temptation to the holy old man, to be an exile from the land of Canaan, for so many years. Be it so, that on account of the famine, he was compelled to go to Egypt; why could he not return when the fifth year was passed? For he did not stupidly lie there in a state of torpor, but he remained quiet, because free egress was not allowed him. Wherefore, also, in this respect, God did not lightly exercise his patience. For, however sweet might be the delights of Egypt, yet he was more than miserable to be deprived of the sight of that land which was the lively figure of his celestial country. With the men of this world, indeed, earthly advantage would have prevailed: but such was the piety of the holy man, that the profit of the flesh weighed nothing against the loss of spiritual good. But he was more deeply wounded, when he saw his death approaching: because, not only was he himself deprived of the inheritance promised to him, but he was leaving his sons, of doubtful, or at least of feeble, faith, buried in Egypt as in a sepulcher. Moreover, his example is proposed to us, that our minds may not languish or become enfeebled by the weariness of a protracted warfare: yea, the more Satan attempts to depress them to the earth, the more fervently let them look and soar towards heaven.
