Only he didn’t buy the land of the priests, for the priests had a portion from Pharaoh, and ate their portion which Pharaoh gave them.
That is why they didn’t sell their land.
Then Joseph said to the people, “Behold, I have bought you and your land today for Pharaoh.
Behold, here is seed for you, and you shall sow the land.
It will happen at the harvests, that you shall give a fifth to Pharaoh, and four parts will be your own, for seed of the field, for your food, for them of your households, and for food for your little ones.”
