Confirmation of the Promise to the Ancestors. 2* Then God spoke to Moses, and said to him: I am the Lord. 3As God the Almighty* I appeareda to Abraham, Isaac, and Jacob, but by my name, Lord, I did not make myself known to them. 4I also established my covenant with them, to give them the land of Canaan, the land in which they were residing as aliens.b 5Now that I have heard the groaning of the Israelites, whom the Egyptians have reduced to slavery, I am mindful of my covenant.c 6Therefore, say to the Israelites: I am the Lord. I will free you from the burdens of the Egyptians and will deliver you from their slavery. I will redeem you by my outstretched arm and with mighty acts of judgment. 7I will take you as my own people, and I will be your God;d and you will know that I, the Lord, am your God who has freed you from the burdens of the Egyptians 8and I will bring you into the land which I swore to give to Abraham, Isaac, and Jacob. I will give it to you as your own possession—I, the Lord! 9But when Moses told this to the Israelites, they would not listen to him because of their dejection and hard slavery.

10Then the Lord spoke to Moses: 11Go, tell Pharaoh, king of Egypt, to let the Israelites leave his land. 12However, Moses protested to the Lord, “If the Israelites did not listen to me, how is it possible that Pharaoh will listen to me, poor speaker* e that I am!” 13But the Lord spoke to Moses and Aaron regarding the Israelites and Pharaoh, king of Egypt, and charged them to bring the Israelites out of the land of Egypt.
