2 Tell Aaron everything I command you, and he will tell the king to let the Israelites leave his country.
3-4 But I will make the king stubborn, and he will not listen to you, no matter how many terrifying things I do in Egypt. Then I will bring severe punishment on Egypt and lead the tribes of my people out of the land.
5 The Egyptians will then know that I am the Lord, when I raise my hand against them and bring the Israelites out of their country.”
6 Moses and Aaron did what the Lord commanded.
7 At the time when they spoke to the king, Moses was eighty years old, and Aaron was 83.
8 The Lord said to Moses and Aaron,
9 “If the king demands that you prove yourselves by performing a miracle, tell Aaron to take his stick and throw it down in front of the king, and it will turn into a snake.”
