Thematic Bible: Sarai

And God said to Abraham, "[as for] Sarai your wife, you shall not call her name Sarai, for Sarah [shall be] her name. 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}?" read more.
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."
