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.

²² For it is written, that Abraham had two sons, the one by a bondmaid, the other by a freewoman.

²¹ But my covenant will I establish with Isaac, which Sarah shall bear unto thee at this set time in the next year.

⁸ And he gave him the covenant of circumcision: and so Abraham begat Isaac, and circumcised him the eighth day; and Isaac begat Jacob; and Jacob begat the twelve patriarchs.

³⁶ And, behold, thy cousin Elisabeth, she hath also conceived a son in her old age: and this is the sixth month with her, who was called barren.

²⁴ And after those days his wife Elisabeth conceived, and hid herself five months, saying,

²⁵ Thus hath the Lord dealt with me in the days wherein he looked on me, to take away my reproach among men.

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.

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.

¹⁹ And God said, Sarah thy wife shall bear thee a son indeed; and thou shalt call his name Isaac: and I will establish my covenant with him for an everlasting covenant, and with his seed after him.
