Genesis 41:1-4

Two full years later, Pharaoh dreamed that he was standing on the bank of the Nile River. In his dream he saw seven fat, healthy cows come up out of the river and begin grazing in the marsh grass. Then he saw seven more cows come up behind them from the Nile, but these were scrawny and thin. These cows stood beside the fat cows on the riverbank. Then the scrawny, thin cows ate the seven healthy, fat cows! At this point in the dream, Pharaoh woke up.
