I know that scripture well, but still don't find anything about 70 metal books in Scripture. I reckon you can say whatever you want, but it aint in there. POWDERMAN.
I re-read that passage several times as well, and even with my limited reading comprehension skills I can tell the difference between a sealed scroll in the right hand of he who sits on the throne, and 70 lead books from a cave in jordan.
In TM7's defence he/she did just repost an article from dailymail that was obviously sensationalized.
If these do turn out to be early Christian writings (pre-paul and canonization) then they may very well be signifiant.
