This evening by Minchah is struck me this year to look at the Megillah through the lens of
the current daf yomi: Hagodas Eydus.
The hinge of the story is "Ein Esther magedes" vs. "Ki higida Esther mah hu la."
Hagodas Eydus comes from the term for speech called Hagada.
Hagada is "devarim ha'kashim k'giddim" (Rashi on "Ko somar l'Bais Yaakov v'sageid
l'Bnei Yisroel" - Shemos 19).
Hagada also is clearly related to the word "Gad," which means "mazal" ("Ha'orchim
la'Gad Shulchan" - Yeshaya 65).
A mazal is a form of hamshacha - of flow from the Heavens.
That is why the Targum for "Mishchu u'kechu lachem" (Shemos 12) is "negidu"
and that is why a king is called a "Nagid" - because he draws and pulls the nation
in a certain direction.
It is interesting, in this respect, that the letters with destructive sounds -
reish and ayin - cut off the hamshacha - gadar and gada',
[I think a beged is called a beged because the type of clothing a person wears
indicates his station - his capacity to be mamshich - which is merumaz in the megillah,
of course in Esther and Mordechai's begadim.
Also, although I can think of Kabblistic reasons why G-D is hamshacha,
I think a pashut reason is that Aleph-Bais is Av, the father,
so Gimmel-Daled is the hamshacha from the Av. Once we're on a tangent,
I would also note the mazal of Adar is Dagim - D-G/G-D.
Still, we have more to cover here before we get to Eydus.
Why is Torah called "devarim ha'kashim k'gidim?"
I am sure we can know with the "pashut" reason, that it is difficult to fulfill
and has many punishments.
But lefi devareinu the peshat is that until Mattan Torah:
"Amudei shomayim yerofafu" (Iyov 26), that the Beriah was not firm until Mattan Torah
- what made the Beriah firm was Mattan Torah.
Also, the Navi says the Avodah Zarah of Gad was to set a table before it, as above.
Rashi brings down at the beginning of Mishpatim that Moseh Rabbeinu was to give
the Torah to Am Yisroel "k'shulchan aruch" - the set tale of the Torah brings
the proper hamshocho or mazal me'meromim instead of the Avodah Zarah
setting of the literal table.
