Genesis 41:28-36

This will happen as I told you. God is showing the king what he is about to do. You will have seven years of good crops and plenty to eat in all the land of Egypt. But after those seven years, there will come seven years of hunger, and all the food that grew in the land of Egypt will be forgotten. The time of hunger will eat up the land. People will forget what it was like to have plenty of food, because the hunger that follows will be so great. You had two dreams which mean the same thing. This shows that God has firmly decided that this will happen, and he will make it happen soon. “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.”
