Genesis 41:17-21

Then Pharaoh said, In my dream I was by the side of the Nile: And out of the Nile came seven cows, fat and good-looking, and their food was the river-grass; Then after them came seven other cows, very thin and poor-looking, worse than any I ever saw in the land of Egypt; And the thin cows made a meal of the seven fat cows who came up first; And even with the fat cows inside them they seemed as bad as before. And so I came out of my sleep.
