Genesis 41:30-34

and after them seven years of famine will come, and all the abundance will be forgotten in the land of Egypt, and the famine will ravage the land.

So the abundance will be unknown in the land because of that subsequent famine; for it will be very severe.

Now as for the repeating of the dream to Pharaoh twice, it means that the matter is confirmed by God, and God will quickly bring it about.

So now let Pharaoh look for a man discerning and wise, and appoint him over the land of Egypt.

Let Pharaoh take action to appoint overseers in charge of the land, and let him take a fifth of the produce of the land of Egypt as a tax in the seven years of abundance.
