Genesis 41:29-37

Indeed seven years of great plenty will come throughout all the land of Egypt; but after them seven years of famine will arise, and all the plenty will be forgotten in the land of Egypt; and the famine will deplete the land. So the plenty will not be known in the land because of the famine following, for it will be very severe. And the dream was repeated to Pharaoh twice because the thing is established by God, and God will shortly bring it to pass. “Now therefore, let Pharaoh select a discerning and wise man, and set him over the land of Egypt. Let Pharaoh do this, and let him appoint officers over the land, to collect one-fifth of the produce of the land of Egypt in the seven plentiful years. And let them gather all the food of those good years that are coming, and store up grain under the authority of Pharaoh, and let them keep food in the cities. Then that food shall be as a reserve for the land for the seven years of famine which shall be in the land of Egypt, that the land may not perish during the famine.” So the advice was good in the eyes of Pharaoh and in the eyes of all his servants.
