Genesis 41:25-27

Then Joseph said to Pharaoh, “The dreams of Pharaoh are one; God has shown Pharaoh what He is about to do: The seven good cows are seven years, and the seven good heads are seven years; the dreams are one. And the seven thin and ugly cows which came up after them are seven years, and the seven empty heads blighted by the east wind are seven years of famine.
