Yoma 33A

לכך שנינו: רוב אחד בעוף ורוב שנים בבהמה. וכי מאחר דאפילו פסולא מדרבנן ליכא, למה לי למרק! מצוה למרק.

therefore, we learned again: The majority of one organ in a bird and the majority of each of two organs in an animal, to teach that slaughtering the majority of each of the signs is sufficient. The Talmud asks: And since there is not even an invalidation by rabbinic law, why do I need another priest to finish cutting the organs? Why not suffice with the High Priest’s slaughter of the majority of each of the two organs? The Talmud answers: It is nevertheless a mitzva to complete the slaughter ab initio to cause the blood to flow more freely.

אביי מסדר מערכה משמיה דגמרא ואליבא דאבא שאול: מערכה גדולה קודמת למערכה שניה של קטורת, מערכה שניה של קטורת קודמת לסידור שני גזירי עצים, וסידור שני גזירי עצים קודם לדישון מזבח הפנימי, ודישון מזבח הפנימי קודם להטבת חמש נרות,

§ Abaye arranged the sequence of the daily services in the Temple based on tradition and in accordance with the opinion of Abba Shaul: Setting up the large arrangement of wood on the altar on which the offerings were burned precedes the second arrangement of wood. This second arrangement was arranged separately near the southwest corner of the altar, and twice every day priests raked coals from it and placed them on the inner altar in order to burn the incense. The second arrangement for the incense precedes setting up the two logs of wood above the large arrangement to fulfill the mitzva of bringing wood. And the setting up of the two logs of wood precedes the removal of ashes from the inner altar. And the removal of ashes from the inner altar precedes the removal of ashes from 5 of the 7 lamps of the candelabrum.

והטבת חמש נרות קודם לדם התמיד, ודם התמיד קודם להטבת שתי נרות, והטבת שתי נרות קודם לקטורת, וקטורת קודם לאברים, ואברים למנחה, ומנחה לחביתין, וחביתין לנסכין,

And removal of ashes from 5 lamps precedes the slaughter and the receiving and sprinkling of the blood of the daily morning offering. The sprinkling of the blood of the daily offering precedes the removal of ashes from the two remaining lamps of the candelabrum. And the removal of ashes from two lamps precedes the burning of the incense. The burning of the incense on the inner altar precedes the burning of the limbs of the daily offering on the outer altar. The burning of the limbs precedes the sacrifice of the meal-offering which accompanies the daily offering. The sacrifice of the meal-offering precedes the sacrifice of the High Priest’s daily griddle-cake offering, half of which he sacrificed in the morning and half in the afternoon. And the griddle-cake offering precedes the pouring of the libations of the daily offering.
