Isaac’s Birth Promised

15 And God said to Abraham, “As for Sarai your wife, you shall not call her name Sarai, but Sarah4 shall be her name. 16 I will bless her, and moreover, I will cgive5 you a son by her. I will bless her, and dshe shall become nations; kings of peoples shall come from her.” 17 Then Abraham efell on his face fand laughed and said to himself, “Shall a child be born to a man who is a hundred years old? Shall Sarah, who is ninety years old, bear a child?” 18 And Abraham said to God, “Oh that Ishmael might live before you!” 19 God said, “No, but gSarah your wife shall bear you a son, and you shall call his name hIsaac.6 I will establish my covenant with him as an everlasting covenant for his offspring after him. 20 As for Ishmael, I have heard you; behold, I have blessed him and will make him fruitful and imultiply him greatly. He jshall father twelve princes, and kI will make him into a great nation. 21 But lI will establish my covenant with Isaac, mwhom Sarah shall bear to you at this time next year.”

22 When he had finished talking with him, nGod went up from Abraham.
