Genesis 47:19-26

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.

21As for the people, he made them all slaves, from one end of Egypt to the other.

22The only land he did not buy was the land belonging to the priests. They received an allotment of food directly from Pharaoh, so they didn’t need to sell their land.

23Then Joseph said to the people, “Look, today I have bought you and your land for Pharaoh. I will provide you with seed so you can plant the fields.

24Then when you harvest it, one-fifth of your crop will belong to Pharaoh. You may keep the remaining four-fifths as seed for your fields and as food for you, your households, and your little ones.”

25“You have saved our lives!” they exclaimed. “May it please you, my lord, to let us be Pharaoh’s servants.”

26Joseph then issued a decree still in effect in the land of Egypt, that Pharaoh should receive one-fifth of all the crops grown on his land. Only the land belonging to the priests was not given to Pharaoh.
