¹⁵ And God said to Abraham, “As for Sarai your wife, you shall not call her name Sarai, but Sarah^[1] shall be her name. ¹⁶ 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.” ¹⁷ 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, and will Sarah, who is ninety years old, bear a child?” ¹⁸ And Abraham said to God, “Oh that Ishmael might live before You!” ¹⁹ 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.

⁹ Then they said to him, “Where is Sarah your wife?” And he said, “There, in the tent.” ¹⁰ Jehovah said, “I will surely return to you about this time next year, and Sarah your wife shall have a son.” And Sarah was listening at the tent door behind him. ¹¹ Now Abraham and Sarah were old, advanced in years. The way of women had ceased to be with Sarah. ¹² Sarah laughed to herself, saying, “After I have become old, shall I have pleasure, my lord being old also?” ¹³ Jehovah said to Abraham, “Why did Sarah laugh and say, ‘Shall I indeed bear a child, now that I am old?’ ¹⁴ Is anything too hard for the Lord? At the appointed time I will return to you, about this time next year, and Sarah shall have a son.” ¹⁵ But Sarah denied it, saying, “I did not laugh,” for she was afraid. He said, “No, but you did laugh.”
