Exodus 7:1-6 NRS

1 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 Israelites go out of his land.
3 But I will harden Pharaoh's heart, and I will multiply my signs and wonders in the land of Egypt.
4 When Pharaoh does not listen to you, I will lay my hand upon Egypt and bring my people the Israelites, company by company, 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 the Israelites out from among them."
6 Moses and Aaron did so; they did just as the Lord commanded them.
