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.
