And I will establish my covenant between me and thee and thy seed after thee throughout their generations for an everlasting covenant, to be a God to thee and to thy seed after thee.

He who is born in thy house, and he who is bought with thy money, must be circumcised. And my covenant shall be in your flesh for an everlasting covenant.

And God said, No, but Sarah thy wife shall bear thee a son, and thou shall call his name Isaac. And I will establish my covenant with him for an everlasting covenant for his seed after him.
