Genesis 41:34-36

Let Pharaoh appoint other officials throughout the land to collect one-fifth of all the crops each year during the seven plentiful years. Have them gather all the food of these abundant years that are coming, and under Pharaoh’s authority, have the grain stored in the cities for food. Store it all as food reserve for the people during the seven years of famine coming upon Egypt, so that the land will survive the famine.”
