Genesis 47:17-21

So they brought their livestock to Joseph, and Joseph gave them food in exchange for the horses and the flocks and the herds and the donkeys; and he fed them with food in exchange for all their livestock that year.

But when that year ended, they came to him the next year and said to him, “We will not hide from my lord the fact that our money is all spent, and the livestock are my lord’s. There is nothing left for my lord except our bodies and our lands.

Why should we die before your eyes, both we and our land? Buy us and our land for food, and we and our land will be slaves to Pharaoh. So give us seed, so that we may live and not die, and that the land may not be desolate.” Result of the Famine

So Joseph bought all the land of Egypt for Pharaoh, for every Egyptian sold his field, because the famine was severe upon them. So the land became Pharaoh’s.

As for the people, he relocated them to the cities from one end of Egypt’s border to the other.
