Esau said, “Is he not rightly named Jacob? For he has supplanted me these two times. He took away my birthright; and behold, now he has taken away my blessing.” Then he said, “Have you not reserved a blessing for me?”
And he gave him the covenant of circumcision. And so Abraham became the father of Isaac, and circumcised him on the eighth day; and Isaac became the father of Jacob, and Jacob of the twelve patriarchs.
