YLT⁽ⁱ⁾ ¹⁵ And God saith unto Abraham, `Sarai thy wife—thou dost not call her name Sarai, for Sarah is her name; ¹⁶ and I have blessed her, and have also given to thee a son from her; and I have blessed her, and she hath become nations—kings of peoples are from her.' ¹⁷ And Abraham falleth upon his face, and laugheth, and saith in his heart, `To the son of an hundred years is one born? or doth Sarah—daughter of ninety years—bear?' ¹⁸ And Abraham saith unto God, `O that Ishmael may live before Thee;' ¹⁹ and God saith, `Sarah thy wife is certainly bearing a son to thee, and thou hast called his name Isaac, and I have established My covenant with him, for a covenant age-during, to his seed after him.
