Genesis 17:16–21

I will bless her, and moreover, I will give you a son by her. I will bless her, and she shall become nations; kings of peoples shall come from her.” Then Abraham fell on his face and laughed and said to himself, “Shall a child be born to a man who is a hundred years old? Shall Sarah, who is ninety years old, bear a child?” And Abraham said to God, “Oh that Ishmael might live before you!” God said, “No, but Sarah your wife shall bear you a son, and you shall call his name Isaac. I will establish my covenant with him as an everlasting covenant for his offspring after him. As for Ishmael, I have heard you; behold, I have blessed him and will make him fruitful and multiply him greatly. He shall father twelve princes, and I will make him into a great nation. But I will establish my covenant with Isaac, whom Sarah shall bear to you at this time next year.”

I will bless her and will surely give you a son by her. I will bless her so that she will be the mother of nations; kings of peoples will come from her.”

Abraham fell facedown; he laughed and said to himself, “Will a son be born to a man a hundred years old? Will Sarah bear a child at the age of ninety?” And Abraham said to God, “If only Ishmael might live under your blessing!”

Then God said, “Yes, but your wife Sarah will bear you a son, and you will call him Isaac. I will establish my covenant with him as an everlasting covenant for his descendants after him. And as for Ishmael, I have heard you: I will surely bless him; I will make him fruitful and will greatly increase his numbers. He will be the father of twelve rulers, and I will make him into a great nation. But my covenant I will establish with Isaac, whom Sarah will bear to you by this time next year.”

I will bless her; indeed, I will give you a son by her. I will bless her, and she will produce nations; kings of peoples will come from her.”

Abraham fell facedown. Then he laughed and said to himself, “Can a child be born to a hundred-year-old man? Can Sarah, a ninety-year-old woman, give birth?” So Abraham said to God, “If only Ishmael were acceptable to you!”

But God said, “No. Your wife Sarah will bear you a son, and you will name him Isaac. I will confirm my covenant with him as a permanent covenant for his future offspring. As for Ishmael, I have heard you. I will certainly bless him; I will make him fruitful and will multiply him greatly. He will father twelve tribal leaders, and I will make him into a great nation. But I will confirm my covenant with Isaac, whom Sarah will bear to you at this time next year.”

And I will bless her and give you a son from her! Yes, I will bless her richly, and she will become the mother of many nations. Kings of nations will be among her descendants.”

Then Abraham bowed down to the ground, but he laughed to himself in disbelief. “How could I become a father at the age of 100?” he thought. “And how can Sarah have a baby when she is ninety years old?” So Abraham said to God, “May Ishmael live under your special blessing!”

But God replied, “No—Sarah, your wife, will give birth to a son for you. You will name him Isaac, and I will confirm my covenant with him and his descendants as an everlasting covenant. As for Ishmael, I will bless him also, just as you have asked. I will make him extremely fruitful and multiply his descendants. He will become the father of twelve princes, and I will make him a great nation. But my covenant will be confirmed with Isaac, who will be born to you and Sarah about this time next year.”

And I will bless her; moreover, I give to you from her a son. And I will bless her, and she shall give rise to nations. Kings of peoples shall come from her.” And Abraham fell upon his face and laughed. And he said in his heart, “Can a child be born to a man a hundred years old, or can Sarah bear a child at ninety?” And Abraham said to God, “Oh that Ishmael might live before you!” And God said, “No, but Sarah your wife shall bear a son for you, and you shall call his name Isaac. And I will establish my covenant with him as an everlasting covenant to his offspring after him. And as for Ishmael, I have heard you. Behold, I will bless him and I will make him fruitful, and I will multiply him exceedingly. He shall father 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 appointed time next year.”

And I will bless her, and give thee a son also of her: yea, I will bless her, and she shall be a mother of nations; kings of people shall be of her. Then Abraham fell upon his face, and laughed, and said in his heart, Shall a child be born unto him that is an hundred years old? and shall Sarah, that is ninety years old, bear? And Abraham said unto God, O that Ishmael might live before thee! And God said, Sarah thy wife shall bear thee a son indeed; and thou shalt call his name Isaac: and I will establish my covenant with him for an everlasting covenant, and with his seed after him. And as for Ishmael, I have heard thee: Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly; twelve princes shall he beget, and I will make him a great nation. But my covenant will I establish with Isaac, which Sarah shall bear unto thee at this set time in the next year.
