What does Genesis 47:22 mean?
People must eat to survive. The only source of food during a crippling seven-year famine has been Joseph, second-in-command to Pharaoh over all the land of Egypt (Genesis 41:44). The people have spent all their cash, have traded all their livestock, and now have sold their land and their freedom to Pharaoh. He owns everything (Genesis 47:13–21).The one exception are the priests. Priests facilitated the worship of the various gods the Egyptians served. Priests were prominent people in society supported by Pharaoh himself with a fixed income. As such, they would have continued to have money to use to buy food from Joseph. They had no need to sell their land to Pharaoh to get food. In this way, the temples and the priest class maintained a level of independence from Pharaoh.
