Exodus 6:30–7:7

30 But Moses said to the LORD, “Behold, I am of uncircumcised lips. How will Pharaoh listen to me?”

Moses and Aaron Before Pharaoh

1 And the LORD said to Moses, “See, I have made you like God to Pharaoh, 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 people of Israel go out of his land. 3 But I will harden Pharaoh’s heart, and though I multiply my signs and wonders in the land of Egypt, 4 Pharaoh will not listen to you. Then I will lay my hand on Egypt and bring my hosts, my people the children of Israel, out of the land of Egypt by great acts of judgment. 5 The Egyptians shall know that I am the LORD, when I stretch out my hand against Egypt and bring out the people of Israel from among them.” 6 Moses and Aaron did so; they did just as the LORD commanded them. 7 Now Moses was eighty years old, and Aaron eighty-three years old, when they spoke to Pharaoh.
