Note 131
From Chapter 44 of the Decline & Fall

In pure Greekis not a common word; nor can the proper meaning, fornication, be strictly applied to matrimonial sin. In a figurative sense, how far, and to what offences, may it be extended? Did Christ speak the Rabbinical or Syriac tongue? Of what original word is the translation? How variously is that Greek word translated in the versions ancient and modern! There are two (Mark, x. 11, Luke, xvi. 18) to one (Matthew, xix. 9) that such ground of divorce was not excepted by Jesus. Some critics have presumed to think, by an evasive answer, he avoided the giving offence either to the school of Sammai or to that of Hillel (Selden, Uxor Ebraica, l. iii. c. 18 - 22, 28, 31.).
