Exodus 6:6-8

Young's Literal Translation

⁶ `Therefore say to the sons of Israel, I [am] Jehovah, and I have brought you out from under the burdens of the Egyptians, and have delivered you from their service, and have redeemed you by a stretched-out arm, and by great judgments,

⁷ and have taken you to Me for a people, and I have been to you for God, and ye have known that I [am] Jehovah your God, who is bringing you out from under the burdens of the Egyptians;

⁸ and I have brought you in unto the land which I have lifted up My hand to give it to Abraham, to Isaac, and to Jacob, and have given it to you -- a possession; I [am] Jehovah.'
