Genesis 41:34

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

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

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

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

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

36 And the food shall be for a store to the land against the seven years of famine, which shall be in the land of Egypt; that the land perish not through the famine.

37 And the thing was good in the eyes of Pharaoh, and in the eyes of all his servants.
