Genesis 41:33

31and the plenty will not be known in the land by reason of that famine which follows; for it will be very grievous.

32The dream was doubled to Pharaoh, because the thing is established by God, and God will shortly bring it to pass.

33“Now therefore let Pharaoh look for a discreet and wise man, and set him over the land of Egypt.

34Let Pharaoh do this, and let him appoint overseers over the land, and take up the fifth part of the land of Egypt’s produce in the seven plenteous years.

35Let them gather all the food of these good years that come, and store grain under the hand of Pharaoh for food in the cities, and let them keep it.
