Genesis 17:15-22

New Revised Standard Version Catholic Edition

¹⁵ God said to Abraham, “As for Sarai your wife, you shall not call her Sarai, but Sarah shall be her name. ¹⁶ 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.” ¹⁷ 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?” ¹⁸ And Abraham said to God, “O that Ishmael might live in your sight!” ¹⁹ God said, “No, but your wife Sarah shall bear you a son, and you shall name him Isaac.^[a] I will establish my covenant with him as an everlasting covenant for his offspring after him. ²⁰ 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. ²¹ But my covenant I will establish with Isaac, whom Sarah shall bear to you at this season next year.” ²² And when he had finished talking with him, God went up from Abraham.
