וְהִקְרִ֧יב אַהֲרֹ֛ן אֶת־פַּ֥ר הַחַטָּ֖את אֲשֶׁר־ל֑וֹ וְכִפֶּ֥ר בַּעֲד֖וֹ וּבְעַ֥ד בֵּיתֽוֹ׃
E Aharon oferecerá o novilho da oferta pelo pecado que é para ele e fará expiação por si mesmo e por sua casa.
Mishnah Yoma
Seven days before Yom HaKippurim they remove the high priest from his house to the chamber of the counselors and they set up another priest to take his place lest something should occur to him to disqualify him [from being able to worship]. Rabbi Judah said: they even prepare another wife for him in case his wife should die, as it says “And he shall make atonement for himself and for his house” (Leviticus 16:6): “his house” this refers to his wife. They said to him: if so there would be no end to the matter.
Mishnah Zevachim
Which is the place [for the offering] of the sacrifices?Most holy sacrifices are slaughtered on the north [side of the altar]. The bullock and the goat of Yom Kippur are [done] at the north, and the receiving of their blood is [performed] with ministering vessels at the north, and their blood requires sprinkling between the poles [of the ark], on the curtain, and on the golden altar. [The omission of] a single application of [the blood] invalidates [them]. He [the priest] would pour out the remainders of the blood on the western base of the outer altar, but if he did not pour it out, he did not invalidate [the sacrifice].
