This Shabbos, the last Shabbos before Pesach, is called שבת הגדול - the great Shabbos. Or is it? Have no fear. I am certainly not doubting that it is שבת הגדול. But is that really what the term means? Shabbos is found all over Tana"ch as being feminine. Therefore, the term for the great Shabbos should have been Shabbos HaGedolah. One is lead to believe that the term Shabbos HaGadol must truly mean the Shabbos of the Gadol. Incidentally, this would change the pronunciation from Shabbos to Shabbas. So if it is the Shabbos of the Gadol - what does that mean?
I have heard a number of answers on this subject but I found many to be unsatisfactory. There seem to be two viable options. First, perhaps the term skips a word. It is the Shabbos of "something" great. This is most commonly used to refer to it as the Shabbos of the great miracle that was entailed in B'nei Yisroel's gathering of the Korban Pesach unharmed. (For an alternate approach to what that something might be see
this post.)
I heard in the name of R' Yaakov Kaminetzky that the term is not meant to be a gramatical conjugation but rather, it follows the same pattern as Shabbas Chazon, Shabbas Nachamu and Shabbas Shuvah. It is merely referring to a significant word in the haftarah for this occasion. In our case, it is a reference to the end of the Haftarah, when HaShem proclaims, (Malachi 3:23) "Hinei anochi sholei'ach lachem es Eliyah HaNavi lifnei bo yom HaShem hagadol vehanora." This pasuk refers to the coming of Eliyahu HaNavi before the great and awesome day of HaShem - the ultimate redemption. Shabbas HaGadol is a direct reference to the word hagadol in this pasuk.
This approach gives great significance to the name and plays beautifully into the theme of the day. Whereas Chazon, Nachamu and Shuvah are all the first words of their respective haftaros, HaGadol is not, certainly indicating a special meaning. Just as this pasuk in the Haftarah gets us ready for the ultimate redemption, on this Shabbos we are readying ourselves for the celebration of the great redemption from Egypt. This pasuk gets us in the
geulah mood which allows us to better appreciate the seder and its
geulah theme.
