Genesis 47:20-26

20So Joseph bought all the land of Egypt for Pharaoh, for 1every Egyptian sold his field, because the famine was severe upon them. So the land became Pharaoh’s. 21As for the people, he relocated them to the cities from one end of Egypt’s border to the other. 22Only the land of the priests he did not buy, because the priests had an allotment from Pharaoh, and they 2lived off the allotment which Pharaoh gave them. Therefore, they did not sell their land. 23Then Joseph said to the people, “Behold, today I have purchased you and your land for Pharaoh; now, here is seed for you, and you may sow the land. 243At the harvest you shall give a 4fifth to Pharaoh, and 5four-fifths shall be your own for seed of the field and for your food, and for those of your households and as food for your little ones.” 25So they said, “You have saved our lives! Let us find favor in the sight of my lord, and we will be Pharaoh’s slaves.” 26Joseph made it a statute concerning the land of Egypt, valid to this day, that Pharaoh was to have the fifth; 6only the land of the priests 7did not become Pharaoh’s.
