Exodus 6:7-8

6:7 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. 6:8 And I will bring you in unto the land, concerning the which I did swear to give it to Abraham, to Isaac, and to Jacob; and I will give it you for an heritage: I [am] the LORD.
