Exodus 6:4-8

And I have also established my covenant with them, to give them the land of Canaan, the land of their sojournings, wherein they sojourned. And moreover I have heard the groaning of the children of Israel, whom the Egyptians keep in bondage; and I have remembered my covenant. Wherefore say unto the children of Israel, I am Jehovah, and I will bring you out from under the burdens of the Egyptians, and I will rid you out of their bondage, and I will redeem you with an outstretched arm, and with great judgments: and I will take you to me for a people, and I will be to you a God; and ye shall know that I am Jehovah your God, who bringeth you out from under the burdens of the Egyptians. And I will bring you in unto the land which I sware to give to Abraham, to Isaac, and to Jacob; and I will give it you for a heritage: I am Jehovah.
