Kislev and the tribe of Gad

Shem m'Shmuel writes (Chayei Sarah 5672) that if you pair the order in which the  shevatim were born with the months of the year, the month of Kislev connects with the tribe of Gad who was blessed with courage and might:

הנה לפי סדר לידת השבטים מתיחס חודש כסלו לגד,..., והנה גד מתברך מיאע"ה וממרע"ה בגבורה ובניצוח האויבים, גד גדוד יגודנו והוא יגוד עקב, ברוך מרחיב גד כלביא שכן וטרף זרוע אף קדקוד, והרמב"ן במדבר הביא מדרש בענין דגל ראובן, ראובן בתשובה וגד בגבורה ושמעון באמצע לכפר עליו

This is why the Chashmonaim were victorious in this month, and IY"H we will emerge victorious in our current battle.

I would suggest that there is another connection as well.  We read in Zos haBracha (33:21) regarding Gad  וַיַּ֤רְא רֵאשִׁית֙ ל֔וֹ כִּי־שָׁ֛ם חֶלְקַ֥ת מְחֹקֵ֖ק סָפ֑וּן.  Rashi explains

 ראה ליטול לו חלק בארץ סיחון ועוג, שהיא ראשית כיבוש הארץ, כי ידע אשר שם בנחלתו חלקת שדה קבורת מחוקק הוא משה   

Gad wanted their portion of land to be in Eiver haYarden because they knew this would be the burial place of Moshe.  It's not that Gad knew that a burial plot near the Rebbe was worth a premium price.  When we read in Matos that וּמִקְנֶ֣ה׀ רַ֗ב הָיָ֞ה לִבְנֵ֧י רְאוּבֵ֛ן וְלִבְנֵי־גָ֖ד, what it means, says R' Bunim m'Peshischa, is that Reuvain and Gad had a kinyan, an attachment, to the רַ֗ב, to Moshe Rabeinu.  They did not want to leave his presence even after Moshe was no longer in this world. (I don't know how you read the whole rest of that parsha that seems to focus on the sheep and cattle, unless maybe it was all a smokescreen.)  It is this powerful connection to Moshe Rabeinu that Gad had which is the antidote to להשׁכּיחם תורתך, the aim of Yavan.
