Genesis 47:18-20

18But that year ended, and the next year they came again and said, “We cannot hide the truth from you, my lord. Our money is gone, and all our livestock and cattle are yours. We have nothing left to give but our bodies and our land.

19Why should we die before your very eyes? Buy us and our land in exchange for food; we offer our land and ourselves as slaves for Pharaoh. Just give us grain so we may live and not die, and so the land does not become empty and desolate.”

20So Joseph bought all the land of Egypt for Pharaoh. All the Egyptians sold him their fields because the famine was so severe, and soon all the land belonged to Pharaoh.
