위임식은 칠 일 동안 행하나니 위임식이 마치는 날까지 칠 일 동안은 회막문에 나가지 말라
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.
