6 Therefore say unto the sons of Israel, I am the Lord, and I will bring you out from under the burdens of the Egyptians, and I will free 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 as my people, and I will be your God: and ye shall know that I am the Lord your God, who brought you out from under the burdens of the Egyptians.
8 And I will bring you in unto the land, concerning which I raised my hand to give it to Abraham, to Isaac, and to Jacob; and I will give it unto you for a heritage: I am the Lord.
9 In this manner Moses spoke unto the sons of Israel, but they did not hearken unto Moses because of their anguish of spirit and cruel bondage.
10 And the Lord spoke unto Moses, saying,
11 Go in, speak unto Pharaoh, king of Egypt, that he let the sons of Israel go out of his land.
12 And Moses answered before the Lord, saying, Behold, the sons of Israel do not hearken unto me; how then shall Pharaoh hear me, seeing I am of uncircumcised lips?
