The Lord said to Moses and Aaron,
Moses was 80 years old and Aaron was 83 when they talked to Pharaoh.
“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.”
You saw the miraculous signs and deeds he did in Egypt to Pharaoh (the king of Egypt) and to his whole country.
