Let Pharaoh do this, and let him appoint officers over the land, and take up the fifth part of the land of Egypt in the seven plenteous years.
Appoint officers over the land - overseers, equivalent to the beys of modern Egypt.
Take up the fifth part of the land - i:e., of the land produce to be purchased or levied as a tax and stored by government, instead, of being sold to foreign grain merchants.
