Genesis 18:12-14 Young's Literal Translation (YLT)
12 and Abraham and Sarah [are] aged, entering into days -- the way of women hath ceased to be to Sarah;
13 and Sarah laugheth in her heart, saying, `After I have waxed old I have had pleasure! -- my lord also [is] old!'
14 And Jehovah saith unto Abraham, `Why [is] this? Sarah hath laughed, saying, Is it true really -- I bear -- and I am aged? Is any thing too wonderful for Jehovah? at the appointed time I return unto thee, about the time of life, and Sarah hath a son.'
