Genesis 41:25-27, 33-36

Then Joseph said to Pharaoh, “The dreams of Pharaoh are one; God has shown Pharaoh what He is about to do: The seven good cows are seven years, and the seven good heads are seven years; the dreams are one. And the seven thin and ugly cows which came up after them are seven years, and the seven empty heads blighted by the east wind are seven years of famine.

“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.”
