Yoma 32A

עשרה קידושין. אלא לרבנן, תשעה הוו! אמרי לך רבנן: קידושא בתרא, כי פשיט בגדי קדש ולביש בגדי חול, עביד ליה התם.

10 sanctifications, as according to his opinion each of the 5 immersions is accompanied by two sanctifications. However, according to the opinion of the Rabbis who do not require sanctification before donning the garments for the first time, only 9 sanctifications are performed. The Talmud answers that The Rabbis could have said to you: With regard to the final sanctification, when he removes the sacred garments and dons non-sacred garments, he performs it there. According to the Rabbis’ opinion, he sanctifies his hands and his feet when he removes the sacred garments. R' Meir holds that sanctification of his hands and feet is performed only before donning sacred garments.

תנו רבנן: ״ובא אהרן אל אהל מועד״, למה הוא בא? אינו בא אלא להוציא את הכף ואת המחתה. (שכל) הפרשה כולה נאמרה על הסדר, חוץ מפסוק זה. מאי טעמא?

§ A baraita states the following with regard to the verse: “And Aaron should come into the Tent of Meeting” (Leviticus 16:23). Why does he come there? He already completed the service in the Sanctuary. He comes only to remove the spoon and the coal pan that he left in the Holy of Holies, as the entire Torah portion in which the Yom Kippur service is discussed was stated in the order in which it is performed in the Temple except for this verse, which should have been written after the sacrifice of the burnt-offering in the following verse. The High Priest does not remove the spoon immediately after he places it in the Holy of Holies. Rather, after placing it there, he emerges and performs certain services outside the Sanctuary and changes his garments again. The Talmud asks: What is the reason that the High Priest interrupts the inner rite of the incense to offer his ram and the people’s ram before removing the spoon and the coal pan?
