'Establish My Covenant' in the Bible

And I will establish my covenant with you, and you must go into the ark--you, and your sons, and your wife, and the wives of your sons with you.

And I will establish my covenant between me and you, and between your offspring after you, throughout their generations as an everlasting covenant to be as God for you and to your offspring after you.

And God said, "No, but Sarah your wife shall bear a son for you, and you shall call his name Isaac. And I will establish my covenant with him as an everlasting covenant to his offspring after him.
