Exactly. We're at the mercy of what I call "the accident of preservation."
Even with the
inscriptions, Aramaic, items like the Lachish Letters and such, the corpus we
have is just too
small to make the kinds of conclusions that Hurvitz does. His three-part
test is thus invalid
and cannot be used effectively to date a book like Qohelet, unless one is
already
predisposed to accept his conclusions.
