There is little doubt that Pharaoh claiming not to know the Lord is basically Pharaoh saying that the Lord of Israel is no match for him. The reality is that the Egyptians have held the Israelites for 400 some years and their God has not acted on their behalf so what can their God really do? Pharaoh heard the Lord’s warning through Moses, and should know that God means business. So, how much business does the Lord really mean? Is the Lord really ready to deliver his people from the Egyptian bondage? What can such a message declare about the Lord’s Sabbath rest?
