15God also said to Abraham, “As for Sarai your wife, you are no longer to call her Sarai; her name will be Sarah.
16I 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.” 17Abraham 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?”
