Exodus 6:5-7

King James Version

⁵ And I have also heard the groaning of the children of Israel, whom the Egyptians keep in bondage; and I have remembered my covenant.

⁶ Wherefore say unto the children of Israel, I am the Lord, 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 a stretched out arm, and with great judgments:

⁷ 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 the Lord your God, which bringeth you out from under the burdens of the Egyptians.
