Genesis 47:24-26 The Voice (VOICE)
24 When the harvest arrives, you will be required to give one-fifth of what you produce to Pharaoh; and four-fifths will be your own to plant the fields and feed your families, households, and children.
Egyptians: 25 You have saved our lives. If it pleases my lord, we are honored to serve as slaves to Pharaoh under these terms.
26 So Joseph made a law regarding the land of Egypt—which stands to this day—declaring Pharaoh is due one-fifth of all the land produces. Only the land of the priests remained personal property.
