¹⁰ And he said, I will certainly return unto thee according to the time of life; and, lo, Sarah thy wife shall have a son. And Sarah heard it in the tent door, which was behind him.

¹⁴ Is any thing too hard for the Lord? At the time appointed I will return unto thee, according to the time of life, and Sarah shall have a son.

21 And the Lord visited Sarah as he had said, and the Lord did unto Sarah as he had spoken.

² For Sarah conceived, and bare Abraham a son in his old age, at the set time of which God had spoken to him.

¹¹ Through faith also Sara herself received strength to conceive seed, and was delivered of a child when she was past age, because she judged him faithful who had promised.

¹³ For the promise, that he should be the heir of the world, was not to Abraham, or to his seed, through the law, but through the righteousness of faith.

⁷ Neither, because they are the seed of Abraham, are they all children: but, In Isaac shall thy seed be called.

⁸ That is, They which are the children of the flesh, these are not the children of God: but the children of the promise are counted for the seed.

⁹ For this is the word of promise, At this time will I come, and Sarah shall have a son.
