Genesis 47:25

²³And Joseph said to all the Egyptians, Behold, I have bought you and your land this day for Pharaoh; take seed for you, and sow the land.

²⁴And there shall be the fruits of it; and ye shall give the fifth part to Pharaoh, and the four remaining parts shall be for yourselves, for seed for the earth, and for food for you, and all that are in your houses.

— Genesis 47:25 —

²⁶And Joseph appointed it to them for an ordinance until this day; to reserve a fifth part for Pharaoh, on the land of Egypt, except only the land of the priests, that was not Pharaoh’s.

²⁷And Israel dwelt in Egypt, in the land of Goshen, and they gained an inheritance upon it; and they increased and multiplied very greatly.
