Exodus 7:1-7 - Yahweh's Plans For Bringing Israel Out Of Egypt
1 The LORD said unto Moses, See, I have constituted thee as god unto Pharaoh; and Aaron, thy brother, shall be thy prophet. 2 Thou shalt speak all that I shall command thee; and Aaron, thy brother, shall speak unto Pharaoh that he send the sons of Israel 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 And Pharaoh shall not hearken unto you, but I shall lay my hand upon Egypt and bring forth my hosts, and my people, the sons of Israel, out of the land of Egypt by great judgments. 5 And the Egyptians shall know that I am the LORD when I stretch forth my hand upon Egypt and bring out the sons of Israel from among them.
6 And Moses and Aaron did as the LORD commanded them, so did they. 7 And Moses was eighty years old and Aaron eighty-three years old when they spoke unto Pharaoh.
