Exodus 7:1-7 - Yahweh's Plans For Bringing Israel Out Of Egypt
1 And the LORD said unto Moses, See, I have made you a god to Pharaoh: and Aaron your brother shall be your prophet. 2 You shall speak all that I command you: and Aaron your brother shall speak unto Pharaoh, that he send the children 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 But Pharaoh shall not hearken unto you, that I may lay my hand upon Egypt, and bring forth my armies, and my people the children 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 children of Israel from among them.
6 And Moses and Aaron did as the LORD commanded them, so did they. 7 And Moses was fourscore years old, and Aaron fourscore and three years old, when they spoke unto Pharaoh.
