Yes, of course, we're talking about the english translation of the Talmud. You're wondering WHY is this resource so 'all fired important'. (http://www.logos.com/product/6667/babylonian-and-jerusalem-talmud-collection)
Well, Lightfoot explains it himself in his 'Commentary on the NT and Hebraica' (an excellent Logos resource, I might add). Yes, looking at 1 Cor 7:3 ...
Lightfoot, with an obviously red-face says 'Modesty forbids to relate their [ed. the rabbis'] trifles; I had rather the reader should go to them himself than defile our paper with them.'
Yes, there are some things you just HAVE to go to the Talmud for. Else-wise, it's just too embarrassing!
