Exodus 6:28-7:7

American Standard Version

²⁸ And it came to pass on the day when Jehovah spake unto Moses in the land of Egypt, ²⁹ that Jehovah spake unto Moses, saying, I am Jehovah: speak thou unto Pharaoh king of Egypt all that I speak unto thee. ³⁰ And Moses said before Jehovah, Behold, I am of uncircumcised lips, and how shall Pharaoh hearken unto me?

7 And Jehovah said unto Moses, See, I have made thee as 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 harden Pharaoh’s heart, and multiply my signs and my wonders in the land of Egypt. ⁴ But 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 upon Egypt, and bring out the children of Israel from among them. ⁶ And Moses and Aaron did so; as Jehovah commanded them, so did they. ⁷ And Moses was fourscore years old, and Aaron fourscore and three years old, when they spake unto Pharaoh.
