Exodus 6:6; Exodus 6:7

6 "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.

7 '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.
