The Lord said to Moses, "I have made you like God to the king of Egypt, and your brother Aaron will be like a prophet for you.
Tell Aaron your brother everything that I command you, and let him tell the king of Egypt to let the Israelites leave his country.
But I will make the king stubborn. I will do many miracles in Egypt,
but he will still refuse to listen. So then I will punish Egypt terribly, and I will lead my divisions, my people the Israelites, out of that land.
I will punish Egypt with my power, and I will bring the Israelites out of that land. Then they will know I am the Lord."
Moses and Aaron did just as the Lord had commanded them.
Moses was eighty years old and Aaron was eighty-three when they spoke to the king.
