3 But I will make Pharaoh stubborn so that he will not do what you tell him. Then I will do many miracles in Egypt to prove who I am.
4 But he will still refuse to listen. So then I will punish Egypt very much. And I will lead my army, my people, out of that land.
5 I will punish the people of Egypt, and they will learn that I am the Lord. Then I will lead my people out of their country.”
6 Moses and Aaron did what the Lord told them.
7 Moses was 80 years old at the time, and Aaron was 83.
8 The Lord said to Moses and Aaron,
9 “Pharaoh will ask you to prove your power. He will ask you to do a miracle. Tell Aaron to throw his walking stick on the ground. While Pharaoh is watching, the stick will become a snake.”
