Genesis 41:21

and behold, seven fat and sleek cattle came up out of the river. They fed in the marsh grass;

and behold, seven other cattle came up after them, poor and very ugly and thin, such as I never saw in all the land of Egypt for ugliness.

The thin and ugly cattle ate up the first seven fat cattle;

I saw in my dream, and behold, seven heads of grain came up on one stalk, full and good;

and behold, seven heads of grain, withered, thin, and blasted with the east wind, sprung up after them.

The thin heads of grain swallowed up the seven good heads of grain. I told it to the magicians, but there was no one who could explain it to me.”
