Genesis 41:25-27, 33-36

Then Joseph said to the king, “Both of these dreams mean the same thing. God is telling you what he is about to do. The seven good cows stand for seven years, and the seven good heads of grain stand for seven years. Both dreams mean the same thing. The seven thin and ugly cows stand for seven years, and the seven thin heads of grain burned by the hot east wind stand for seven years of hunger.

“So let the king choose a man who is very wise and understanding and set him over the land of Egypt. And let the king also appoint officers over the land, who should take one-fifth of all the food that is grown during the seven good years. They should gather all the food that is produced during the good years that are coming, and under the king’s authority they should store the grain in the cities and guard it. That food should be saved to use during the seven years of hunger that will come on the land of Egypt. Then the people in Egypt will not die during the seven years of hunger.”
