² For Sarah ^(A)conceived and bore Abraham a son in his old age, ^(B)at the set time of which God had spoken to him.

¹¹ By faith ^(A)Sarah herself also received strength to conceive seed, and ^(B)she^[a] bore a child when she was past the age, because she judged Him ^(C)faithful who had promised.

²² For it is written that Abraham had two sons: ^(A)the one by a bondwoman, ^(B)the other by a freewoman.

²¹ But My ^(A)covenant I will establish with Isaac, ^(B)whom Sarah shall bear to you at this ^(C)set time next year.”

^8 (A)Then He gave him the covenant of circumcision; ^(B)and so Abraham begot Isaac and circumcised him on the eighth day; ^(C)and Isaac begot Jacob, and ^(D)Jacob begot the twelve patriarchs.

^14 (A)Is anything too hard for the Lord? ^(B)At the appointed time I will return to you, according to the time of life, and Sarah shall have a son.”

¹⁰ And He said, “I will certainly return to you ^(A)according to the time of life, and behold, ^(B)Sarah your wife shall have a son.”

(Sarah was listening in the tent door which was behind him.)

¹⁹ Then God said: “No, ^(A)Sarah your wife shall bear you a son, and you shall call his name Isaac; I will establish My ^(B)covenant with him for an everlasting covenant, and with his descendants after him.

⁹ For this is the word of promise: ^(A)“At this time I will come and Sarah shall have a son.”
