Gen.47.22

Only the land of the priests bought he not; for the priests had a portion assigned them of Pharaoh, and did eat their portion which Pharaoh gave them: wherefore they sold not their lands.

Gen.47.22

Joseph 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.

Gen.47.22

However, he did not buy the land of the priests, because they received a regular allotment from Pharaoh and had food enough from the allotment Pharaoh gave them. That is why they did not sell their land.

Gen.47.22

Only the land of the priests he did not buy; for the priests had rations allotted to them by Pharaoh, and they ate their rations which Pharaoh gave them; therefore they did not sell their lands.
