GREGORY L. DOUDNA has a piece in Bible and Interpretation News:

4Q Pesher Nahum and the Teacher of Righteousness

The true identity of the Teacher of Righteousness�ironically missed in prior discussions and never even considered as a possibility in any prior secondary literature�points to Hyrcanus II.

Greg's theory, which he has published recently in a massive book, is that the Dead Sea Scrolls were actually deposited in the Qumran caves in the first century B.C.E., not 68 C.E. I'm not aware that he's convinced any other Qumran specialists about this, but he's always an interesting read.

Excerpts are going to be scarce for awhile unless the AOL system turns out to be friendlier than my first impression indicates.
