Exodus 7:1-7

1 And Jehovah said to Moses, See, I have made thee God to Pharaoh; and Aaron thy brother shall be thy prophet.
2 Thou shalt speak all that I command thee; and Aaron thy brother shall speak unto Pharaoh, that he let the children of Israel go out of his land.
3 And I will render Pharaoh's heart obdurate, and multiply my signs and my wonders in the land of Egypt.
4 And Pharaoh will not hearken unto you; and I will lay my hand upon Egypt, and bring forth my hosts, my people, the children of Israel, out of the land of Egypt by great judgments.
5 And the Egyptians shall know that I am Jehovah, when I stretch forth my hand on Egypt, and bring out the children of Israel from among them.
6 And Moses and Aaron did as Jehovah had commanded them: so did they.
7 And Moses was eighty years old, and Aaron was eighty-three years old, when they spoke to Pharaoh.
