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.

²⁰ He staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God;

²¹ And being fully persuaded that, what he had promised, he was able also to perform.

²³ Let us hold fast the profession of our faith without wavering; (for he is faithful that promised;)

¹¹ Now Abraham and Sarah were old and well stricken in age; and it ceased to be with Sarah after the manner of women.

¹² Therefore Sarah laughed within herself, saying, After I am waxed old shall I have pleasure, my lord being old also?

¹³ And the Lord said unto Abraham, Wherefore did Sarah laugh, saying, Shall I of a surety bear a child, which am old?

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.
