Scholars call it [the Torah] the Masoretic text. The Masoretes were Hebrew scribes of the first centuries of the present era. They fixed the wording and spelling of the Bible; since then it has not changed. It has long been a matter of critical controversy as to just how accurate the Masoretes were; for one thing, did they have a true text from ancient sources, or did they invent and corrupt? Opinion has swayed back and forth on this point. The excitement over the Dead Sea Scrolls came in part from their substantial authentication of the Masoretic Isaiah.
