The Lord blessed Pharaoh because Pharaoh was blessing Abraham’s descendants (12:3). Through Joseph’s smart management in Egypt, the Lord saved the people from hunger and helped Pharaoh prosper. During the famine, Joseph sold food to the Egyptians, accepting money, livestock, and eventually land as payment. Then Pharaoh owned almost all of Egypt. Meanwhile, God gave Israel some of the best land in Egypt where they could live, work, and multiply.
