⁹ Then they said to him, “Where is Sarah your wife?” And he said, “There, in the tent.” ¹⁰ He said, “I will surely return to you at this ^[a]time next year; and behold, Sarah your wife will have a son.” And Sarah was listening at the tent door, which was behind him.^{(A) 11} Now Abraham and Sarah were old, well advanced in years; she was past [the age of] childbearing. ¹² So Sarah laughed to herself [when she heard the Lord’s words], saying, “After I have become old, shall I have pleasure and delight, my lord (husband) being also old?”^{(B) 13} And the Lord asked Abraham, “Why did Sarah laugh [to herself], saying, ‘Shall I really give birth [to a child] when I am so old?’ ¹⁴ Is anything too difficult or too wonderful for the ^[b]Lord? At the appointed time, when the season [for her delivery] comes, I will return to you and Sarah will have a son.”^{(C) 15} Then Sarah denied it, saying, “I did not laugh”; because she was afraid. And He (the Lord) said, “No, but you did laugh.”

Isaac Is Born

21 The Lord graciously remembered and visited Sarah as He had said, and the Lord did for her as He had promised. ² So Sarah conceived and gave birth to a son for Abraham in his old age, at the appointed time of which God had spoken to him. ³ Abraham named his son Isaac (laughter), the son to whom Sarah gave birth. ⁴ So Abraham circumcised his son Isaac when he was eight days old, just as God had commanded him. ⁵ Abraham was a hundred years old when his son Isaac was born. ⁶ Sarah said, “God has made me laugh; all who hear [about our good news] will laugh with me.” ⁷ And she said, “Who would have said to Abraham that Sarah would nurse children? For I have given birth to a son by him in his old age.”^(A)
