レビ記 16:6

את פרי החטאת אשר לו [AND AARON SHALL OFFER] THE BULL OF SIN OFFERING WHICH IS HIS — i. e. that mentioned above (v. 3). It teaches you here, by adding the words אשר לו, that it came (had to be purchased) from his own and not from the money of the community (Sifra, Acharei Mot, Section 2 2; Yoma 3b). וכפר בעדו ובעד ביתו means, he shall make confession over it of his own sins and of the sins of his house (Sifra, Acharei Mot, Section 2 2; Yoma 36b).

וְהִקְרִ֧יב אַהֲרֹ֛ן אֶת־פַּ֥ר הַחַטָּ֖את אֲשֶׁר־ל֑וֹ וְכִפֶּ֥ר בַּעֲד֖וֹ וּבְעַ֥ד בֵּיתֽוֹ׃

And Aharon shall offer the bullock of the sin offering, which is for himself, and make atonement for himself, and for his house.
