Genesis 47:18-20

18And that year ended; and they came to him the second year, and said to him, We will not hide [it] from my lord that since [our] money is come to an end, and the herds of cattle are in the possession of my lord, nothing is left before my lord but our bodies and our land.

19Why should we die before thine eyes, both we and our land? Buy us and our land for bread, and we and our land will be bondmen to Pharaoh; and give seed, that we may live, and not die, and that the land be not desolate.

20And Joseph bought all the soil of Egypt for Pharaoh; for the Egyptians sold every man his field, because the famine prevailed over them; and the land became Pharaoh's.
