(Mishnah): The Kohen Gadol came to read. If he wants, he reads in the linen garments. If not, he reads in a white cloak of his.

The overseer of the [Beis ha']Keneses [in Har ha'Bayis] takes the Sefer, gives it to the Gabai of the Keneses, and the Gabai gives it to the Segan, and the Segan gives it to the Kohen Gadol, and the Kohen Gadol stands and receives it and reads [Avodas Yom Kipur in] Acharei Mos and "Ach be'Asor'' (the Isurim of Yom Kipur in the same Parshah);

He rolls (closes) the Torah and rests in his garment, and says "more than what I read in front of you is written here'', and "be'Asor'' in Chumash Bamidbar (Musaf Yom Kipur) he reads by heart.
