Genesis 47:18-20

18When that year was over, they came to him the next year and said to him, “We cannot hide from our lord that the money is used up and the livestock and the animals belong to our lord. Nothing remains before our lord except our bodies and our land.

19Why should we die before your very eyes, both we and our land? Buy us and our land in exchange for food, and we, with our land, will become Pharaoh’s slaves. Give us seed that we may live and not die. Then the land will not become desolate.”

20So Joseph bought all the land of Egypt for Pharaoh. Each of the Egyptians sold his field, for the famine was severe. So the land became Pharaoh’s.
