Isaac's Birth Promised

¹⁵ And God said to Abraham, “As for Sarai your wife, you shall not call her name Sarai, but Sarah^[a] shall be her name. ¹⁶ I will bless her, and moreover, I will ^(A)give^[b] you a son by her. I will bless her, and ^(B)she shall become nations; kings of peoples shall come from her.” ¹⁷ Then Abraham ^(C)fell on his face ^(D)and 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 ^(E)Sarah your wife shall bear you a son, and you shall call his name ^(F)Isaac.^[c] 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 ^(G)multiply him greatly. He ^(H)shall father twelve princes, and ^(I)I will make him into a great nation. ²¹ But ^(J)I will establish my covenant with Isaac, ^(K)whom Sarah shall bear to you at this time next year.”
