⁹ And they said to him, Where is Sarah your wife? And he said, [She is here] in the tent.

^10 [a][The Lord] said, I will surely return to you when the season comes round, and behold, Sarah your wife will have a son. And Sarah was listening and heard it at the tent door which was behind Him.^(A)

¹⁵ And God said to Abraham, As for Sarai your wife, you shall not call her name Sarai; but Sarah [Princess] her name shall be.

¹⁶ And I will bless her and give you a son also by her. Yes, I will bless her, and she shall be a mother of nations; kings of peoples shall come from her.

¹⁷ Then Abraham fell on his face and laughed and said in his heart, Shall a child be born to a man who is a hundred years old? And shall Sarah, who is ninety years old, bear a son?

¹⁸ And [he] said to God, Oh, that Ishmael might live before You!

¹⁹ But God said, Sarah your wife shall bear you a son indeed, and you shall call his name Isaac [laughter]; and I will establish My covenant or solemn pledge with him for an everlasting covenant and with his posterity after him.
