Parshas Ki Sisah

The Chafetz Chaim- who was a Kohen- once asked R’ Shimon Schwab “Why aren’t you a Kohen?” R’ Schwab, not knowing what that Chafetz Chaim wanted, answered, “because my father wasn’t a Kohen and nor was his father”. The Chafetz Chaim said that after Klal Yisroel made the Eigal Moshe said ‘Mi l’Hashem alai’ and my great grand father- who was from Shevet Levi answered the call, that is why this Shevet was imbued with extra kedusha. Only Shevet Levi had the courage to stand up for what was right and not get swept up with the masses. That is why i am a Kohen and your not.
How was it that every single descendent of Levi had that courage and not one other Jew was able to join them?

The Rambam in the beginning of hilchos Avodah Zara says that the teachings of Avraham Yitzchak and Yaakov- Yichud Hashem- that Hashem is the sole creator of the universe and he is the only one that runs the world- was all but forgotten from the world- even from Klal Yisroel while they were enslaved in Egypt. The only ones that held on to the teachings of the Avos were the descendants of Levi, the belief in Hashem and his Oneness never left them. Every single descendant of Levi from when they were a newborn in the cradle was ingrained with the emunah of Hashem. The Alter from Navordik says that it is this that gave them the clarity of mind when the world had gone insane. The fact that this teaching wasn’t something they merely learned- but rather it was a deeply rooted tradition that was part of their essence of who they were. When all of Klal Yisroel was lost and was wondering if the true way to serve Hashem is through the Golden Calf- Shevet Levi was able to remain true to their upbringing. The deeper understanding of this is; if something is proven through logic and even if it’s clearly shown to us – it can be disproved if questioned under the wrong circumstances. But if we truly believe in Hashem and believe that he’s that great that we cannot fathom his greatness, then no question or circumstance can change our mind for our belief and tradition is deeper and greater then anything in this world.

Parshas Tetzava

The Baal Haturim points out that Moshe’s name is not mentioned in this weeks Parsha. One of the reasons he says, is that when Moshe was begging Hashem to forgive Klal Yisroel after the sin of the Eigal, he said to Hashem forgive them or erase my name from the Torah. It would seem that this was a punishment for him - offering to be erased from the Torah - so Hashem erased his name from just one Parsha. This is hard to believe for he sacrificed himself for the sake of Klal Yisroel, so why would he be punished? The Chidushai Harim explains this with a Gemorah. The Gemorah (Baba Kamah 60b) says that if one puts himself in danger for the sake of divrei Torah, we don’t say over Halacha in his name. This also is hard to believe that it is a punishment.
Every member of Klal Yisroel’s neshoma is in essence Torah (Yisroel, Torah and Hashem are all one). The only thing that divides us from the Torah is our guf- our physical bodies.
When one puts his life on the line for the sake of Torah, he is detaching his body from his soul and thus all that remains is just the neshoma which is in essence the same as Torah itself. We cannot say over the Torah in his name for being that the Torah is detached from his physical being it’s not his in a phyiscal sense - it’s/he's pure Torah. So too Moshe, being that he gave himself up for the sake of Klal Yisroel got to the level that the torah doesn’t speak about him as it does in the other Parshas, but rather he becomes synonymous with Torah and is addressed just by the word “Vatah”. For in this weeks Parsha Moshe and Torah are one.
P.S. Further study has to be done why this is expressed in Parshas Tetzaveh and not any other parsha. Take a peek at the Alshich in this weeks Parsha, and Masseh Rokeach on the Mishkan.
