Genesis 41:29–32 (KJV)
29Behold, there come seven years of great plenty throughout all the land of Egypt: 30And there shall arise after them seven years of famine; and all the plenty shall be forgotten in the land of Egypt; and the famine shall consume the land; 31And the plenty shall not be known in the land by reason of that famine following; for it shall be very grievous. 32And for that the dream was doubled unto Pharaoh twice; it is because the thing is established by God, and God will shortly bring it to pass.
