1. God calls Moses to go to Egypt. God sees the affliction of His people Israel and wants to put it to an end. But in order for that to happen, a number of things have to happen.
2. God will harden Pharaoh's heart. Because of this, God is going to have to show Pharaoh the power that He has and Pharaoh is going to have to learn (the hard way) of who he is dealing with.
3. Moses shares with Aaron God's instructions. Aaron doesn't yet know that God has made him the person who will be speaking directly to Pharaoh.
