Genesis 41:33-36

Now let Pharaoh look for a man discerning and wise, and set him over the land of Egypt. Let Pharaoh take action to appoint overseers in charge of the land, and let him exact a fifth of the produce of the land of Egypt in the seven years of abundance. Then let them gather all the food of these good years that are coming, and store up the grain for food in the cities under Pharaoh’s authority, and let them guard it. Let the food become as a reserve for the land for the seven years of famine which will occur in the land of Egypt, so that the land will not perish during the famine.”
