John Calvin on Genesis 47:27

27. And Israel dwelt in the land. Moses does not mean that Jacob and his sons were proprietors of that land which Pharaoh had granted them as a dwelling-place, in the same manner in which the other parts of Egypt were given to the inhabitants for a perpetual possession: but that they dwelt there commodiously for a time, and thus were in possession by favor, provided they continued to be peaceable. Hence the cause that they so greatly increased, in a very short space of time. Therefore, what is here related by Moses belongs to the history of the following period; and he now returns to the proper thread of his narrative, in which he purposed to show how God protected his Church from many deaths; and not that only, but wonderfully exalted it by his own secret power.
