Leeser⁽ⁱ⁾ 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, and give thee also a son of her; yea I will bless her, and she shall become a mother of nations; kings of people shall spring from her. ¹⁷ Then Abraham fell upon his face, and laughed; and he said in his heart, Shall a child be born unto him that is a hundred years old? and shall Sarah, who is ninety years old, bear? ¹⁸ And Abraham said unto God, O that Ishmael might live before thee! ¹⁹ And God said, Truly, Sarah thy wife shall bear thee a son; and thou shalt call his name Isaac; and I will establish my covenant with him for an everlasting covenant, for his seed after him.
