28 Now you, brothers, mlike Isaac, nare children of promise.
16 I will bless her, and moreover, I will cgive 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. I will establish my covenant with him as an everlasting covenant for his offspring after him.
10 The Lord said, “I will surely return to you uabout this time next year, and vSarah your wife shall have a son.” And Sarah was listening at the tent door behind him.
14 aIs anything too hard for the Lord? bAt the appointed time I will return to you, about this time next year, and Sarah shall have a son.”

21 The Lord kvisited Sarah as he had said, and the Lord did to Sarah las he had promised.
2 And Sarah mconceived and bore Abraham a son in his old age nat the time of which God had spoken to him.
