[ו:יב-טו] וַיְדַבֵּר יְהוָֹה אֶל משֶׁה לֵּאמֹר: זֶה קָרְבַּן אַהֲרֹן וּבָנָיו אֲשֶׁר יַקְרִיבוּ לַיהֹוָה בְּיוֹם הִמָּשַׁח אֹתוֹ עֲשִׂירִת הָאֵפָה סֹלֶת מִנְחָה תָּמִיד מַחֲצִיתָהּ בַּבֹּקֶר וּמַחֲצִיתָהּ בָּעָרֶב: עַל מַחֲבַת בַּשֶּׁמֶן תֵּעָשֶׂה מֻרְבֶּכֶת תְּבִיאֶנָּה תֻּפִינֵי מִנְחַת פִּתִּים תַּקְרִיב רֵיחַ נִיחֹחַ לַיהוָֹה: וְהַכֹּהֵן הַמָּשִׁיחַ תַּחְתָּיו מִבָּנָיו יַעֲשֶׂה אֹתָהּ חָק עוֹלָם לַיהוָֹה כָּלִיל תָּקְטָר:
רש"י פסוק יג
אף ההדיוטות מקריבין עשירית האיפה ביום שהן מתחנכין לעבודה, אבל כהן גדול בכל יום, שנאמר מנחה תמיד וגו' והכהן המשיח תחתיו מבניו וגו' חק עולם וגו'
As explained earlier, all of the details of the avoda contain deep symbolic meaning and moral messages. After all, to Hashem it really doesn’t make any difference what we bring for a korban and how we proceed to offer it. The specifics of why everything must be done a certain way are intended for us, to train us and guide us in our spiritual development.
Consequently, the laws of the korbanos and the details of the Beis Hamikdash are still deeply relevant; as the moral messages are just as applicable even in absence of the actual avoda (may it be speedily restored to us).
A kohen must bring a korban miluim on his inaugural day of service. A kohen gadol, however, is required to bring this korban every single day!
The korban miluim is a rite of passage, one that the average kohen undergoes once in his life as he graduates to a new level of divine service. The kohen gadol must undergo this rite of passage every day, reminding him of the fact that his position is one of subservience to Hashem, not dominance over “lesser” people.
The message would appear to be that those in positions of greatness and leadership should not take their positions for granted. This daily korban is meant to humble him, as he must approach every day in his position with the same eagerness and awe as if it were his first!
