15 God said to Abraham, “As for your wife Sarai, do not call her Sarai, for SarahI will be her name. 16 I will bless her; indeed, I will give you a son by her.l I will bless her, and she will produce nations; kings of peoples will come from her.”

17 Abraham fell facedown. Then he laughedm and said to himself, “Can a child be born to a hundred-year-old man? Can Sarah, a ninety-year-old woman, give birth?” 18 So Abraham said to God, “If only Ishmael were acceptableJ to you!”
