15 And God said unto Abraham, As for Sarai thy wife, thou shalt not call her name Sarai, but ||Sarah shall her name be. 16 And I will bless her, sand give thee a son also of her: yea, I will bless her, and †she shall be a mother tof nations; kings of people shall be of her. 17 Then Abraham fell upon his face, uand laughed, and said in his heart, Shall a child be born unto him that is an hundred years old? and shall Sarah, that is ninety years old, bear? 18 And Abraham said unto God, O that xIshmael might live before thee! 19 And God said, ySarah thy wife shall bear thee a son indeed; and thou shalt call his name Isaac: and I will establish my covenant with him for an everlasting covenant, and with his seed after him. 20 And as for Ishmael, I have heard thee: Behold, I have blessed him, and zwill make him fruitful, and will multiply him exceedingly; atwelve princes shall he beget, band I will make him a great nation. 21 But my covenant will I establish with Isaac, which Sarah shall bear unto thee at this set time in the next year. 22 And he left off talking with him, and cGod went up from Abraham.
