Genesis 41:17-24

Then Pharaoh said to Joseph, “In my dream I was standing on the bank of the Nile, when out of the river there came up seven cows, fat and sleek, and they grazed among the reeds. After them, seven other cows came up—scrawny and very ugly and lean. I had never seen such ugly cows in all the land of Egypt. The lean, ugly cows ate up the seven fat cows that came up first. But even after they ate them, no one could tell that they had done so; they looked just as ugly as before. Then I woke up. “In my dream I saw seven heads of grain, full and good, growing on a single stalk. After them, seven other heads sprouted—withered and thin and scorched by the east wind. The thin heads of grain swallowed up the seven good heads. I told this to the magicians, but none of them could explain it to me.”
