Exodus 6:8

5 And moreover I have 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 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:

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 Jehovah your God, who bringeth you out from under the burdens of the Egyptians.

8 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.

9 And Moses spake so unto the children of Israel: but they hearkened not unto Moses for anguish of spirit, and for cruel bondage.

10 And Jehovah spake unto Moses, saying,

11 Go in, speak unto Pharaoh king of Egypt, that he let the children of Israel go out of his land.
