וַיֹּ֨אמֶר מֹשֶׁ֜ה אֶֽל־אַהֲרֹ֗ן קְרַ֤ב אֶל־הַמִּזְבֵּ֙חַ֙ וַעֲשֵׂ֞ה אֶת־חַטָּֽאתְךָ֙ וְאֶת־עֹ֣לָתֶ֔ךָ וְכַפֵּ֥ר בַּֽעַדְךָ֖ וּבְעַ֣ד הָעָ֑ם וַעֲשֵׂ֞ה אֶת־קָרְבַּ֤ן הָעָם֙ וְכַפֵּ֣ר בַּֽעֲדָ֔ם כַּאֲשֶׁ֖ר צִוָּ֥ה יְהוָֽה׃
그가 또 아론에게 이르되 너는 단에 나아가 네 속죄제와 네 번제를 드려서 너를 위하여, 백성을 위하여 속하고 또 백성의 예물을 드려서 그들을 위하여 속하되 무릇 여호와의 명대로 하라
Tze'enah Ure'enah
“Come forward to the altar” [9:7]. The Midrash says that Aaron thought that the altar was like an ox and he was afraid to approach the altar. He saw an ox standing before him. Thus, Moses came and said to Aaron: my dear brother, do not be afraid. Go to the altar. Ramban writes that one should not understand that Aaron had seen an ox, but Aaron was a righteous person and always had before him, in his thoughts, the sin that he committed, and he had committed no sins except for the making of the Golden Calf. Therefore, the Midrash says, that is to say, that Aaron thought that the sin of the Golden Calf was standing before him. Thus, Moses said to Aaron, go to the altar; your sin has been forgiven. “Making expiation for yourself and for the people” [9:7]. You should make expiation for your sins and afterwards for the sins of the people. Each person should first repair himself and afterwards he should punish the people.5Bahya, Leviticus, 9:7.
Tze'enah Ure'enah
Three sorts of things were offered from the sacrifice. First the fat of the sacrifice, since the fat brings him to all the sins through which he engages in arrogance.

That is to say, when a person is fat, he is quick to commit sins. Then they offered the kidneys, and it is known that the essential advice in the person comes from the kidneys. The person commits sins through the advice of the kidneys. Afterwards, one offers the red meat. This is the blood of the person, which leads the person to sins.6Bahya, Leviticus, 9:9.

קרב אל המזבח [AND MOSES SAID TO AARON] GO TO THE ALTAR, for Aaron was diffident and feared to go there. Moses therefore said to him “Wherefore art thou diffident? For this purpose hast thou been selected!” (cf. Sifra, Shemini, Mechilta d'Miluim 2 8).
