(1) The LORD spoke to Moses, saying: (2) Take Aaron along with his sons, and the vestments, the anointing oil, the bull of sin offering, the two rams, and the basket of unleavened bread; (3) and assemble the whole community at the entrance of the Tent of Meeting.
דָּבָר אַחֵר, וַיַּרְא אַהֲרֹן, מָה רָאָה, אָמַר אַהֲרֹן אִם בּוֹנִין הֵן אוֹתוֹ, הַסִּרְחוֹן נִתְלָה בָּהֶן, מוּטָב שֶׁיִּתָּלֶה הַסִּרְחוֹן בִּי וְלֹא בְּיִשְׂרָאֵל, רַבִּי אַבָּא בַּר יוּדָן בְּשֵׁם רַבִּי אַבָּא מָשָׁל לְבֶן מְלָכִים שֶׁנִּתְגָּאֶה לִבּוֹ עָלָיו וְלָקַח אֶת הַסַּיִּף לַחְתֹּךְ אֶת אָבִיו, אָמַר לוֹ פַּדְגוֹגוֹ אַל תְּיַגַּע אֶת עַצְמְךָ תֵּן לִי וַאֲנִי חוֹתֵךְ, הֵצִיץ הַמֶּלֶךְ עָלָיו אָמַר לוֹ יוֹדֵעַ אֲנִי לְהֵיכָן הָיְתָה כַּוָּנָתְךָ, מוּטָב שֶׁיִּתָּלֶה הַסִּרְחוֹן בְּךָ וְלֹא בִּבְנִי, חַיֶּיךָ מִן פָּלָטִין דִּידִי לֵית אַתְּ זָיַיע וּמוֹתַר פָּתוֹרִי אַתְּ אָכֵיל, עֶשְׂרִים וְאַרְבַּע אֲנוֹנָס אַתְּ נָסֵיב. כָּךְ מִן פָּלָטִין דִּילִי לֵית אַתְּ זָיַיע (ויקרא כא, יב): וּמִן הַמִּקְדָּשׁ לֹא יֵצֵא, וּמוֹתַר פָּתוֹרִי אַתְּ אָכֵיל, (ויקרא ב, ג): וְהַנּוֹתֶרֶת מִן הַמִּנְחָה, עֶשְׂרִים וְאַרְבָּעָה אֲנוֹנָס אַתְּ נָסֵיב, אֵלּוּ עֶשְׂרִים וְאַרְבַּע מַתְּנוֹת כְּהֻנָּה שֶׁנִּתְּנוּה לְאַהֲרֹן וּלְבָנָיו. אָמַר לוֹ הַקָּדוֹשׁ בָּרוּךְ הוּא לְאַהֲרֹן, אָהַבְתָּ צֶדֶק, אָהַבְתָּ לְצַדֵּק אֶת בָּנַי, וְשָׂנֵאתָ מִלְּחַיְבָן, עַל כֵּן מְשָׁחֲךָ אֱלֹקִים אֱלֹקֶיךָ, אָמַר לוֹ חַיֶּיךָ שֶׁמִּכָּל שִׁבְטוֹ שֶׁל לֵוִי לֹא נִבְחַר לִכְהֻנָּה גְדוֹלָה אֶלָּא אַתָּה (ויקרא ח, ב): קַח אֶת אַהֲרֹן וְאֶת בָּנָיו אִתּוֹ.
Another interpretation: "When Aaron saw [the Golden Calf], [he built an altar before it; and Aaron announced: 'Tomorrow shall be a festival of the LORD!']"(Exodus 32:5). What did he see? Thought Aaron: If they build it, the stench of sin hangs on them. Better that the stench of sin hang on me and not on Israel.
Rabbi Abba bar Yudan in the name of Rabbi Abba said: This is comparable to the son of kings whose heart became arrogant and took up a sword to cut down his father. His tutor said to him: "Do not trouble yourself. Give it to me and I will cut!" The King glanced out upon the tutor and said to him: "I know what was your [true] intention. Better that the stench of sin hang on you than on my son. By your life, [as reward] you will not move from my palace, and the leftovers from my table you will eat, and you will take twenty-four portion of rations."
So too: You [Aaron] will not move from my palace: "He shall not go outside the sanctuary"(Leviticus 21:12), and the leftovers from my table you will eat: "And the remainder of the meal offering [shall be for Aaron and his sons,]"(Leviticus 2:3) and twenty-four portions of rations you will take. These are the twenty-four gifts of the priesthood that were given to Aaron and his sons.
The Holy Blessed One said to Aaron: "You love righteousness (tzedek)" (Psalm 45:8). You love to defend (l'tzadek) my children and hate to make them guilty. "Rightly has God, your God, chosen to anoint you" (ibid.) and said to you, "By your life! Out of the whole tribe of Levi, only you were chosen for the priesthood," as it says "Take Aaron along with his sons [and the vestments and the anointing oil,]" (Leviticus 8:2)
