Genesis 41:26-27

41:26 The seven good cows represent seven years, and the seven good heads of grain represent seven years. Both dreams have the same meaning. 41:27 The seven lean, bad-looking cows that came up after them represent seven years, as do the seven empty heads of grain burned with the east wind. They represent seven years of famine.
