Let Pharaoh do [this],.... Appoint such a person; who as a sovereign prince could do it of himself:and let him appoint officers over the land; not Pharaoh, but the wise and discreet governor he should set over the land, who should have a power of appointing officers or overseers under him to manage things according to his direction:and take up the fifth part of the land of Egypt in the seven plenteous years; not the officers appointed, but the appointer of them, the chief governor under Pharaoh, for the word is singular; it is proposed that he should, in Pharaoh's name, and by his order, take a fifth part of all the corn in the land of Egypt during seven years of plenty; not by force, which so good a man as Joseph would never advise to, whatever power Pharaoh might have, and could exercise if he pleased; but by making a purchase of it, which in such time of plenty would be bought cheap, and which so great a prince as Pharaoh was capable of.
It is commonly asked, why an half part was not ordered to be took up, since there were to be as many years of famine as of plenty?
