And I set up my covenant between me and between thee, and between thy seed after thee to their generations for a covenant of eternity; to be a God to thee and to thy seed after thee.

He shall be circumcised with circumcising, he being born in thy house, and bought with thy silver: and my covenant was in your flesh for an eternal covenant

And God will say. Truly, Sarah thy wife, shall bring forth to thee a son, and shall call his name Isaak: and I set up my covenant with him for a lasting covenant, and to his seed after him.
