Genesis 41:29 (KJV)

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.

And there shall arise after them seven years of famine; and all the plenty shall be forgotten in the land of Egypt; and the famine shall consume the land;

And the plenty shall not be known in the land by reason of that famine following; for it shall be very grievous.

And for that the dream was doubled unto Pharaoh twice; it is because the thing is established by God, and God will shortly bring it to pass.

Now therefore let Pharaoh look out a man discreet and wise, and set him over the land of Egypt.

Let Pharaoh do this, and let him appoint officers over the land, and take up the fifth part of the land of Egypt in the seven plenteous years.
