Genesis 41:21

18 Seven cows, plump and attractive, came up out of the Nile and fed in the reed grass. 19 Seven other cows came up after them, poor and very ugly and thin, such as I had never seen in all the land of Egypt. 20 And the thin, ugly cows ate up the first seven plump cows, 21 but when they had eaten them no one would have known that they had eaten them, for they were still as ugly as at the beginning. Then I awoke. 22 I also saw in my dream seven ears growing on one stalk, full and good. 23 Seven ears, withered, thin, and blighted by the east wind, sprouted after them, 24 and the thin ears swallowed up the seven good ears. And I told it to the magicians, but there was no one who could explain it to me.”
