Daf Yomi - Sukkah 46 - Heoros on Rashi by Reb Dave

46a – Rashi q.v. Mitzvos Harbeh - Some infer from this Rashi that there is a mitzvah to wear tefillin on Chol Hamoed. Others break up the Rashi into two parts, as though he were saying, “ . . . to take a lulav and to sit in the succah, AND/OR to wear tefilin and to wear tzitiiz”.

46a – Rav Marei the son of Bas Shmuel – Rashi in Berachos explains why we refer to him with reference to him being “the son of the daughter of Shmuel”, a most unusual appellation.

46b – Rashi q.v. visameinu libracha – Note how Rashi emphasizes the test as “yom shemini chag atzeres hazeh”. He spells it all out again on 47a q.v. beruchi loh mivorchinon, and a third time on 47b q.v. bircas hamazon. It is unusual that Rashi would go to the extreme of writing out the full text three times in such close succession. To me it is clear that Rashi knew other opinions held the correct formulation is “ yom shemin atzeres hachag hazeh”, and he therefore emphasized that the correct opinion is otherwise.
