Genesis 47:20-22

King James Version

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

²¹ And as for the people, he removed them to cities from one end of the borders of Egypt even to the other end thereof.

²² Only the land of the priests bought he not; for the priests had a portion assigned them of Pharaoh, and did eat their portion which Pharaoh gave them: wherefore they sold not their lands.
