3 But I will make Pharaoh stubborn. Even though I will do many miraculous signs and amazing things in Egypt,
4 Pharaoh will not listen to you. Then I will use my power to punish Egypt severely, and I will bring my people, the Israelites, out of Egypt in organized family groups.
5 The Egyptians will know that I am the Lord when I use my power against Egypt and bring the Israelites out of there.”
6 Moses and Aaron did as the Lord had commanded them.
7 Moses was 80 years old and Aaron was 83 when they talked to Pharaoh.
8 The Lord said to Moses and Aaron,
9 “When Pharaoh says to you, ‘Give me a sign to prove that God has sent you,’ tell Aaron, ‘Take your shepherd’s staff and throw it down in front of Pharaoh,’ and it will become a large snake.”
