Exodus 7:1-7 - Yahweh's Plans For Bringing Israel Out Of Egypt
1 Then the Lord said to Moses, “Now hear this: I make you as God to Pharaoh [to declare My will and purpose to him]; and your brother Aaron shall be your prophet. 2 You shall speak all that I command you, and your brother Aaron shall tell Pharaoh to let the children of Israel go out of his land. 3 And I will make Pharaoh’s heart hard, and multiply My signs and My wonders (miracles) in the land of Egypt. 4 But Pharaoh will not listen to you, and I shall lay My hand on Egypt and bring out My hosts [like a defensive army, tribe by tribe], My people the children of Israel, out of the land of Egypt by great acts of judgment (the plagues). 5 The Egyptians shall know that I am the Lord, when I stretch out My hand on Egypt and bring out the children of Israel from among them.”
6 And Moses and Aaron did so; just as the Lord commanded them, so they did. 7 Now Moses was eighty years old and Aaron eighty-three years old when they spoke to Pharaoh.
