But God said, “No, but Sarah your wife will bear you a son, and you shall call his name Isaac; and I will establish My covenant with him for an everlasting covenant for his seed after him.
So God said to Abraham, “Do not be distressed because of the boy and your maidservant; whatever Sarah tells you, listen to her voice, for through Isaac your seed shall be named.
Then He said, “Take now your son, your only one, whom you love, Isaac, and go forth to the land of Moriah, and offer him there as a burnt offering on one of the mountains of which I will tell you.”
And He gave him the covenant of circumcision; and so Abraham was the father of Isaac, and circumcised him on the eighth day; and Isaac was the father of Jacob, and Jacob of the twelve patriarchs.
