Exodus 6:2-9 New Revised Standard Version (NRSV)
2 God also spoke to Moses and said to him: “I am the Lord. 3 I appeared to Abraham, Isaac, and Jacob as God Almighty,[a] but by my name ‘The Lord’[b] 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 resided as aliens. 5 I have also heard the groaning of the Israelites whom the Egyptians are holding as slaves, and I have remembered my covenant. 6 Say therefore to the Israelites, ‘I am the Lord, and I will free you from the burdens of the Egyptians and deliver you from slavery to them. I will redeem you with an outstretched arm and with mighty acts of judgment. 7 I will take you as my people, and I will be your God. You shall know that I am the Lord your God, who has freed you from the burdens of the Egyptians. 8 I will bring you into the land that I swore to give to Abraham, Isaac, and Jacob; I will give it to you for a possession. I am the Lord.’” 9 Moses told this to the Israelites; but they would not listen to Moses, because of their broken spirit and their cruel slavery.
