Genesis 41:25-31

25At this, Joseph said to Pharaoh, “The dreams of Pharaoh are one and the same. God has revealed to Pharaoh what He is about to do. 26The seven good cows are seven years, and the seven ripe heads of grain are seven years. The dreams have the same meaning. 27Moreover, the seven thin, ugly cows that came up after them are seven years, and so are the seven worthless heads of grain scorched by the east wind—they are seven years of famine.

28It is just as I said to Pharaoh: God has shown Pharaoh what He is about to do. 29Behold, seven years of great abundance are coming throughout the land of Egypt, 30but seven years of famine will follow them. Then all the abundance in the land of Egypt will be forgotten, and the famine will devastate the land. 31The abundance in the land will not be remembered, since the famine that follows it will be so severe.
