Genesis 41:31-35

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.

Then have them collect all the food of these good years that are coming, and store up the grain for food in the cities under Pharaoh’s authority, and have them guard it.
