Genesis 47, 22 – 26 „Only the priests’ lands Joseph did not acquire. Since the priests had a fixed allowance from Pharaoh and lived off the allowance Pharaoh had granted them, they did not have to sell their land. 23Joseph told the people: Now that I have acquired you and your land for Pharaoh, here is your seed for sowing the land. 24But when the harvest is in, you must give a fifth of it to Pharaoh, while you keep four-fifths as seed for your fields and as food for yourselves and your households and as food for your children. 25You have saved our lives! they answered. We have found favor with my lord; now we will be Pharaoh’s slaves. 26Thus Joseph made it a statute for the land of Egypt, which is still in force, that a fifth of its produce should go to Pharaoh. Only the land of the priests did not pass over to Pharaoh”.
