For so long time as her husband liveth (ep oson cronon zh o anhr auth). While he lives (twi zwnti andri) Paul says in Romans 7:2 . This is the ideal and is pertinent today when husbands meet their ex-wives and wives meet their ex-husbands. There is a screw loose somewhere. Paul here treats as a sort of addendum the remarriage of widows. He will discuss it again in 1 Timothy 5:9-13 and then he will advise younger widows to marry. Paul leaves her free here also to be married again, "only in the Lord" (monon en Kuriwi). Every marriage ought to be "in the Lord." To be married (gamhqhnai) is first aorist passive infinitive followed by the dative relative wi with unexpressed antecedent toutwi.
