Genesis 41:17-24
41:17 Then Pharaoh said to Joseph, “In my dream I was standing by the edge of the Nile.
41:18 Then seven fat and fine-looking cows were coming up out of the Nile, and they grazed in the reeds.
41:19 Then seven other cows came up after them; they were scrawny, very bad-looking, and lean. I had never seen such bad-looking cows as these in all the land of Egypt!
41:20 The lean, bad-looking cows ate up the seven fat cows.
41:21 When they had eaten them, no one would have known that they had done so, for they were just as bad-looking as before. Then I woke up.
41:22 I also saw in my dream seven heads of grain growing on one stalk, full and good.
41:23 Then seven heads of grain, withered and thin and burned with the east wind, were sprouting up after them.
41:24 The thin heads of grain swallowed up the seven good heads of grain. So I told all this to the diviner-priests, but no one could tell me its meaning.”
