Genesis 41:23 (KJV)

And, behold, there came up out of the river seven kine, fatfleshed and well favoured; and they fed in a meadow:

And, behold, seven other kine came up after them, poor and very ill favoured and leanfleshed, such as I never saw in all the land of Egypt for badness:

And the lean and the ill favoured kine did eat up the first seven fat kine:

And when they had eaten them up, it could not be known that they had eaten them; but they were still ill favoured, as at the beginning. So I awoke.

And I saw in my dream, and, behold, seven ears came up in one stalk, full and good:

And the thin ears devoured the seven good ears: and I told this unto the magicians; but there was none that could declare it to me.

And Joseph said unto Pharaoh, The dream of Pharaoh is one: God hath shewed Pharaoh what he is about to do.

The seven good kine are seven years; and the seven good ears are seven years: the dream is one.

And the seven thin and ill favoured kine that came up after them are seven years; and the seven empty ears blasted with the east wind shall be seven years of famine.

This is the thing which I have spoken unto Pharaoh: What God is about to do he sheweth unto Pharaoh.
