Exodus 6:2-8

God spoke further to Moses and said to him, “I am the LORD; and I appeared to Abraham, Isaac, and Jacob, as God Almighty, but by My name, 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 sojourned. Furthermore I have heard the groaning of the sons of Israel, because the Egyptians are holding them in bondage, and I have remembered My covenant. Say, therefore, to the sons 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 their bondage. I will also redeem you with an outstretched arm and with great judgments. Then I will take you for My people, and I will be your God; and you shall know that I am the LORD your God, who brought you out from under the burdens of the Egyptians. I will bring you to the land which I swore to give to Abraham, Isaac, and Jacob, and I will give it to you for a possession; I am the LORD.’ ”
