Genesis 41:25

23and behold, seven heads of grain, withered, thin, and blasted with the east wind, sprung up after them.

24The thin heads of grain swallowed up the seven good heads of grain. I told it to the magicians, but there was no one who could explain it to me.”

25Joseph said to Pharaoh, “The dream of Pharaoh is one. What God is about to do he has declared to Pharaoh.

26The seven good cattle are seven years; and the seven good heads of grain are seven years. The dream is one.

27The seven thin and ugly cattle that came up after them are seven years, and also the seven empty heads of grain blasted with the east wind; they will be seven years of famine.
