Genesis 18:9-14 American Standard Version (ASV)
9 And they said unto him, Where is Sarah thy wife? And he said, Behold, in the tent. 10 And he said, I will certainly return unto thee when the season [a]cometh round; and, lo, Sarah thy wife shall have a son. And Sarah heard in the tent door, which was behind him. 11 Now Abraham and Sarah were old, and well stricken in age; it had ceased to be with Sarah after the manner of women. 12 And Sarah laughed within herself, saying, After I am waxed old shall I have pleasure, my lord being old also? 13 And Jehovah said unto Abraham, Wherefore did Sarah laugh, saying, Shall I of a surety bear a child, who am old? 14 Is anything too [b]hard for Jehovah? At the set time I will return unto thee, when the season cometh round, and Sarah shall have a son.
