Then the LORD said to Moses, "See, I have made you like God1 to Pharaoh, and your brother Aaron will be your prophet.22
You are to say everything I command you, and your brother Aaron is to tell Pharaoh to let the Israelites go out of his country.
But I will harden Pharaoh's heart,3 and though I multiply my miraculous signs and wonders4 in Egypt,
he will not listen5 to you. Then I will lay my hand on Egypt and with mighty acts of judgment6 I will bring out my divisions,7 my people the Israelites.
And the Egyptians will know that I am the LORD8 when I stretch out my hand9 against Egypt and bring the Israelites out of it."
Moses and Aaron did just as the LORD commanded10 them.
Moses was eighty years old11 and Aaron eighty-three when they spoke to Pharaoh.
