Exodus 6:5-7

5And I have heard also the groaning of the children of Israel, whom the Egyptians have forced to serve, and I have remembered my covenant.

6Therefore 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 deliver you from their service, and I will redeem you with a stretched-out arm, and with great judgments.

7And I will take you to me for a people, and will be your 1God; and ye shall know that I, Jehovah your 2God, am he who bringeth you out from under the burdens of the Egyptians.
