The comment and the ensuing thread quoted at the bottom of this question make me wonder what, exactly, was buried at Qumran.
Were the items buried there actually used at some point and later placed there for safekeeping, or were they scribal errors that were placed there out of reverence because, although they were written as holy texts, they were ultimately incorrectly written/copied?
I know that there is no consensus as to their origin or the reason they were buried there, and thus no consensus as to whether they provide historical proof about accuracy or inaccuracy in our own texts; but has any noted Posek stated that these texts were errors (or even deliberate violations of the correct Mesorah which we have today) and put there to keep them out of use?
I heard recently that R"T's order is not something that was not something that he made up; rather, there is a mesorah for it. Archaeological evidence has been found in the Qumran caves of the Dead Sea Scrolls. – Adam Mosheh Dec 30 '11 at 5:39
I think I read in Ben Ish Hai that they found Tefilin buried next to Yehezkel's grave and I think he said they are Rabenu Taam's... – Hacham Gabriel Dec 30 '11 at 5:57
@HachamGabriel, interesting. – Adam Mosheh Dec 30 '11 at 6:19
@HachamGabriel In the end of the first Bach in Siman 34 the Bach quotes a Smag and Mordechai saying that it was Rashi tfillin buried there. Some say that it was because Rashis are pasul and that's why they were buried there. The Bach says that it couldn't be for that reason as one could just change the order of the parshios and doesn't have to bury them. – Shmuel Brin Mar 2 at 18:43
