Genesis 41:23-27

and behold, seven ears, withered, thin, and scorched by the east wind sprouted up after them;

and the thin ears swallowed the seven good ears. Then I told it to the soothsayer priests, but there was no one who could explain it to me.”

And Joseph said to Pharaoh, “Pharaoh’s dreams are one and the same; God has told to Pharaoh what He is about to do.

The seven good cows are seven years; and the seven good ears are seven years; the dreams are one and the same.

The seven thin and ugly cows that came up after them are seven years, and the seven thin ears scorched by the east wind will be seven years of famine.
