Exodus 6:2–13
[2] God spoke to Moses and said to him, “I am the LORD. [3] I appeared to Abraham, to Isaac, and to Jacob, as God Almighty, but by my name the LORD I did not make myself known to them. [4] I also established my covenant with them to give them the land of Canaan, the land in which they lived as sojourners. [5] Moreover, I have heard the groaning of the people of Israel whom the Egyptians hold as slaves, and I have remembered my covenant. [6] Say therefore to the people of Israel, ‘I am the LORD, and I will bring you out from under the burdens of the Egyptians, and I will deliver you from slavery to them, and I will redeem you with an outstretched arm and with great acts of judgment. [7] I will take you to be my people, and I will be your God, and you shall know that I am the LORD your God, who has brought you out from under the burdens of the Egyptians. [8] I will bring you into the land that I swore to give to Abraham, to Isaac, and to Jacob. I will give it to you for a possession. I am the LORD.’” [9] Moses spoke thus to the people of Israel, but they did not listen to Moses, because of their broken spirit and harsh slavery.
[10] So the LORD said to Moses, [11] “Go in, tell Pharaoh king of Egypt to let the people of Israel go out of his land.” [12] But Moses said to the LORD, “Behold, the people of Israel have not listened to me. How then shall Pharaoh listen to me, for I am of uncircumcised lips?” [13] But the LORD spoke to Moses and Aaron and gave them a charge about the people of Israel and about Pharaoh king of Egypt: to bring the people of Israel out of the land of Egypt.
Exodus 7:1–5
[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.”
