20-21So Joseph bought up all the farms in Egypt for Pharaoh. Every Egyptian sold his land—the famine was that bad. That's how Pharaoh ended up owning all the land and the people ended up slaves; Joseph reduced the people to slavery from one end of Egypt to the other.
22Joseph made an exception for the priests. He didn't buy their land because they received a fixed salary from Pharaoh and were able to live off of that salary. So they didn't need to sell their land.
