When Abram was ninety-nine years old, the Lord appeared to Abram, and said to him, “I am God Almighty; walk before me, and be blameless. God said to Abraham, “As for you, you shall keep my covenant, you and your offspring after you throughout their generations. This is my covenant, which you shall keep, between me and you and your offspring after you: Every male among you shall be circumcised.
God said to Abraham, “As for Sarai your wife, you shall not call her Sarai, but Sarah shall be her name. I will bless her, and moreover I will give you a son by her. I will bless her, and she shall give rise to nations; kings of peoples shall come from her.” Then Abraham fell on his face and laughed, and said to himself, “Can a child be born to a man who is a hundred years old? Can Sarah, who is ninety years old, bear a child?” And Abraham said to God, “O that Ishmael might live in your sight!” God said, “No, but your wife Sarah shall bear you a son, and you shall name him Isaac. I will establish my covenant with him as an everlasting covenant for his offspring after him. As for Ishmael, I have heard you; I will bless him and make him fruitful and exceedingly numerous; he shall be the father of twelve princes, and I will make him a great nation. But my covenant I will establish with Isaac, whom Sarah shall bear to you at this season next year.” And when he had finished talking with him, God went up from Abraham.
