Genesis 41:22-26

And I saw in my dream, and, behold, seven ears came up in one stalk, full and good:

And, behold, seven ears, withered, thin, and blasted with the east wind, sprung up after them:

And the thin ears devoured the seven good ears: and I told this unto the magicians; but there was none that could declare it to me.

And Joseph said unto Pharaoh, The dream of Pharaoh is one: God hath shewed Pharaoh what he is about to do.

The seven good kine are seven years; and the seven good ears are seven years: the dream is one.
