Genesis 47:18-20

18When that year was 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 spent; my lord also has our herds of livestock; there is nothing left in the sight of my lord but our bodies and our lands.

19Why should we die before your eyes, both we and our land? Buy us and our land in exchange for food, and we and our land will be servants to Pharaoh. And give us seed [to plant], that we may live and not die, and that the land may not be desolate.”

20So 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.
