Exodus 6:1-8

But the Lord said to Moses, “Now you shall see what I will do to Pharaoh; for with a strong hand he will send them out, and with a strong hand he will drive them out of his land.” God spoke to Moses and said to him, “I am the Lord. 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. I also established my covenant with them to give them the land of Canaan, the land in which they lived as sojourners. Moreover, I have heard the groaning of the people of Israel whom the Egyptians hold as slaves, and I have remembered my covenant. 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. 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. 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.’”
