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.

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.

¹⁵ Then Sarah denied, saying, I laughed not; for she was afraid. And he said, Nay; but thou didst laugh.

¹⁵ And God said unto Abraham, As for Sarai thy wife, thou shalt not call her name Sarai, but Sarah shall her name be.

¹⁶ And I will bless her, and give thee a son also of her: yea, I will bless her, and she shall be a mother of nations; kings of people shall be of her.

¹⁷ Then Abraham fell upon his face, and laughed, and said in his heart, Shall a child be born unto him that is an hundred years old? and shall Sarah, that is ninety years old, bear?

¹⁸ And Abraham said unto God, O that Ishmael might live before thee!

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.

²⁰ And as for Ishmael, I have heard thee: Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly; twelve princes shall he beget, and I will make him a great nation.

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

²² And he left off talking with him, and God went up from Abraham.

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.

³ And Abraham called the name of his son that was born unto him, whom Sarah bare to him, Isaac.

⁴ And Abraham circumcised his son Isaac being eight days old, as God had commanded him.

⁵ And Abraham was an hundred years old, when his son Isaac was born unto him.

⁶ And Sarah said, God hath made me to laugh, so that all that hear will laugh with me.

⁷ And she said, Who would have said unto Abraham, that Sarah should have given children suck? for I have born him a son in his old age.
