Genesis 41:16-20

Joseph then answered Pharaoh, saying, “It has nothing to do with me; God will give Pharaoh an answer for his own good.”

So Pharaoh said to Joseph, “In my dream, there I was, standing on the bank of the Nile;

and behold, seven cows, fat and fine-looking came up out of the Nile, and they grazed in the marsh grass.

Then behold, seven other cows came up after them, poor and very ugly and thin, such as I had never seen for ugliness in all the land of Egypt;

and the thin and ugly cows ate the first seven fat cows.
