Moshe vs. Aharon - 2 Paradigms of Leadership

As far back as I can remember my teachers have told me that in this week's Parsha it says "Vayidom Aharon" as a praise for Aharon's tzidduk hadin even when facing the loss of his two sons. Well, this week when reading the parsha I noticed, for the first time, that that vort is not exactly true to the context of those words.
Here are the psukim in full:

א וַיִּקְחוּ בְנֵי-אַהֲרֹן נָדָב וַאֲבִיהוּא אִישׁ מַחְתָּתוֹ, וַיִּתְּנוּ בָהֵן אֵשׁ, וַיָּשִׂימוּ עָלֶיהָ, קְטֹרֶת; וַיַּקְרִיבוּ לִפְנֵי יְהוָה, אֵשׁ זָרָה--אֲשֶׁר לֹא צִוָּה, אֹתָם. ב וַתֵּצֵא אֵשׁ מִלִּפְנֵי יְהוָה, וַתֹּאכַל אוֹתָם; וַיָּמֻתוּ, לִפְנֵי יְהוָה. ג וַיֹּאמֶר מֹשֶׁה אֶל-אַהֲרֹן, הוּא אֲשֶׁר-דִּבֶּר יְהוָה לֵאמֹר בִּקְרֹבַי אֶקָּדֵשׁ, וְעַל-פְּנֵי כָל-הָעָם, אֶכָּבֵד; וַיִּדֹּם, אַהֲרֹן.

"Vayidom Aharon" is clearly not in response to the death, but in response to Moshe.

I have always found the contrast between Moshe's and Aharon's leadership style very striking. Moshe is aloof and detached - he needs to be told by his father-in-law, a foreigner, that his being solely responsible for the judgement of the people is not best for them; he pitches his tent outside the camp; his brother begs him to daven that Miriam not die when she speaks lashon hara about him; the midrash suggests that he even seperates from his wife. Aharon, on the other hand, is very much a part of the people - he's present during chet ha'egel; the mishna describes him as an "ohev shalom verodef shalom," someone who brings the people together. In modern terms Moshe is the Rosh Yeshiva and Aharon is the community Rav. (There's a lot more that can be said about this, but I'll leave it at this for now."

The 2 stark personality differences come to a bit of a head in our psukim. Following the death of Moshe's nephews his response is to quote a halakha. And then - "vayidom Aharon" - he does not respond to Moshe's seeming callousness (or insert more PC description here in lieu of callousness.)

Shabbat Shalom
