Three Prongs

 ואתה תצוה why does it even need to say ואתה if it is talking about Moshe?  Why should Bnei Yisrael bring שמן זית to Moshe if he is not the one kindling the Menorah?

Moshe's name is not mentioned in this week's parsha.  The Rebbe (Toras Menachem 5751) says that the connection to Moshe in this parsha is a direct connection to the essence of Moshe, ואתה, not limited by his name.  The commandment to kindle the menorah is a command to light up the souls which are called נר and that must be done via Moshe who is the teacher of Klal Yisrael.  Therefore, Moshe's connection to Bnei Yisrael which is innate, not external like a name, is integral to the preparation of the spiritual nature of the menorah. 

The Megillah starts, ends and is middled by the letter ו.  Why does the Megillah contain so many ווין?  As explained in another context the letter ו can be spelled out as וו, ויו,ואו which is 12 for the 12 shevatim, 13 for אחד as a reference to Hashem and 22 for the letters of the aleph beit.  Haman thought that Bnei Yisrael, in their lowly state in golus, both physically and spiritually, were vulnerable.  He thought the connection between Bnei Yisrael and Hashem was broken.  The nes Purim demonstrated that the  ג' דרגין אינון מתקשרן דא בדא קב"ה אורייתא וישראל remained.  Bnei Yisrael were saved, there was a reacceptance of the Torah and ורבים מעמי הארץ מתיהדים.  The 3 ו's at surrounding the Megillah hint that this 3 pronged connection was acknowledged and verified during the story of the Megillah. 

The Gemarah (Megillah 16a) says that when Haman found Mordechai learning about the kemitzah of the omer when Haman came to parade Mordechai around the city he said  בא קומץ שעורים שלכם ודחה עשרת אלפים ככר כסף שלי.  What about the kemitzah puts down Haman?  The Shviley Pinchas says in light of the above idea that the kemitzah symbolizes this eternal bond Klal Yisrael, Hashem and the Torah have.  How so?  Rashi Vayikra (2:1) says the kemitzah is performed with 3 fingers.  The shape of a finger says the Tikkunay Zohar (10, pg. 25a) is like the letter ו.  Hence the three fingered kometz alludes to the connection between Hashem, Klal Yisrael and the Torah which is seen through the letter ו.  

This is the intent of the ו in ואתה תצוה to demonstrate that at all times the Jewish soul has a connectgion to Moshe, to the Torah that is deeply ingrained.
