Captured Light

The Gemorah in Megillah (6a) says אָמַר רַבִּי אֲבָהוּ וְעֶקְרוֹן תֵּעָקֵר זוֹ קֵסָרִי בַּת אֱדוֹם שֶׁהִיא יוֹשֶׁבֶת בֵּין הַחוֹלוֹת וְהִיא הָיְתָה יָתֵד תְּקוּעָה לְיִשְׂרָאֵל בִּימֵי יְווֹנִים וּכְשֶׁגָּבְרָה מַלְכוּת בֵּית חַשְׁמוֹנַאי וְנִצְּחוּם הָיוּ קוֹרִין אוֹתָהּ אַחִידַת מִגְדַּל שִׁיר.  Why did they choose the name מגדל שיר?  What is the significance that בית חשמונאי captured it?  The Maharasha points out that the people that lived בין החולות were the תרמודאיים as the Gemorah in Shabbat (31a) says.  The Gemorah there says that there eyes are narrow because they live in sandy places so that the sand won't enter their eyes (see Rashi there.)  The Gemorah says one must light the Chanukah candles until the תרמודאי come in (Shabbat 21b.)  The תרמודאי represent the power of the Greeks.  The narrow eyes are the eyes narrowed because of the חשך זו יון.  They narrow one's vision to only see the mundane and not see kedusha.  They live בין החולות , between chulin, chol.  They promote an existence of the mundane as the only thing that there is to exist for.  These people occupied קֵסָרִי בַּת אֱדוֹם.  It was the power of the חשמונאים that was able to illuminate even their dark existence.  They renamed it מגדל שיר for the dreidel is like a migdal, it is a mini tower that has the letters נגהש, the gematria of משיח, it reminds us of the אור of moshiach which we are able to tap into for a few days to illuminate the dark days of the golus to lead us to the ultimate שיר, the שיר חדש (based upon a drasha by R' Feuer.)
