Where Is Rashi?

Daf Yomi learners relish when the daf that they learn relates to their daily lives, but that is somewhat difficult with this particular tractate, as nezirim seem hard to find. Some suggest that perhaps for this reason Tractate Nazir wasn’t studied regularly in ancient yeshivos and that is why the text of Nazir is not consistent with other tractates of Shas. Certain phrases are employed differently than elsewhere in the Talmud.
The Rosh often makes note of this in his commentary. For example, on 19b, he writes, “Shitas nazir meshuneh.” We find the same phenomenon in regard to Tractate Nedarim. Another similarity between the two masechtos is the lack of Rashi’s commentary. In regard to Nedarim, it is almost universally accepted that the commentary printed with the Vilna Shas and labeled as Rashi was not written by Rashi. In relation to Nazir, the authorship of the commentary printed in Rashi’s place is a matter of some dispute. Some say that it is certainly not Rashi, while others say it is at the very least based on Rashi’s commentary. Many opine that it was written by Rashi’s son-in-law. Rashi’s commentary is the standard one used when learning any Gemara, but in these two tractates, students tend to use other commentaries in place of the one printed as Rashi.
