קרב אל המזבח. שֶׁהָיָה אַהֲרֹן בּוֹשׁ וְיָרֵא לָגֶשֶׁת, אָמַר לוֹ מֹשֶׁה, לָמָּה אַתָּה בוֹשׁ? לְכָךְ נִבְחַרְתָּ
[AND MOSES SAID TO AARON] GO TO THE MIZBEACH, for Aaron was embarrassed and afraid to go there. Moshe, therefore, said to him “Why are you embarrassed (and afraid)? For this purpose you have been chosen!”
ותצא אש. רַ' אֱלִיעֶזֶר אוֹמֵר לֹא מֵתוּ בְנֵי אַהֲרֹן אֶלָּא עַל יְדֵי שֶׁהוֹרוּ הֲלָכָה בִּפְנֵי מֹשֶׁה רַבָּן, רַבִּי יִשְׁמָעֵאל אוֹמֵר שְׁתוּיֵי יַיִן נִכְנְסוּ לַמִּקְדָּשׁ, תֵּדַע, שֶׁאַחַר מִיתָתָן הִזְהִיר הַנּוֹתָרִים שֶׁלֹּא יִכָּנְסוּ שְׁתוּיֵי יַיִן לַמִּקְדָּשׁ, מָשָׁל לְמֶלֶךְ שֶׁהָיָה לוֹ בֶן בַּיִת וְכוּ', כִּדְאִיתָא בְּוַיִּקְרָא רַבָּה:
AND THERE WENT OUT FIRE — Rabbi Eleizer said: the sons of Aaron died only because they gave decisions on religious matters in the presence of their teacher, Moshe. Rabbi Ishmael said: they died because they entered the Sanctuary drunk by wine. You may know that this is because, because after their death he scolded those who survived that they should not enter when drunk by wine. It's like a parable of the King...
וידם אהרן. קִבֵּל שָׂכָר עַל שְׁתִיקָתוֹ, וּמַה שָּׂכָר קִבֵּל? שֶׁנִּתְיַחֵד עִמּוֹ הַדִּבּוּר — שֶׁנֶּאֶמְרָה לוֹ לְבַדּוֹ פָּרָשַׁת שְׁתוּיֵי יַיִן
AND AARON WAS SILENT — He received a reward for his silence. And what reward did he get? That the next Mitzvah from Hashem was said to him, and not Moshe.
וייטב בעיניו. הוֹדָה וְלֹא בוֹשׁ לוֹמַר לֹא שָׁמַעְתִּי (זבחים ק"א):
AND IT WAS PLEASING IN HIS EYES — He admitted his error and was not ashamed to do so, by saying (instead of admitting it) “I have not heard a statement (from God regarding this)", but rather he said, “I have heard, but I forgot it”
