Yoma 26B

ההוא דלא כרבי אליעזר בן יעקב ודלא כרבי יהודה.

the opinion of that tanna would be in accordance with neither the opinion of R' Eliezer ben Ya’akov nor the opinion of R' Yehuda, as these 5 lotteries would include one for carrying the coal pan and another one for taking the limbs up to the altar.

מתני׳ תמיד קרב בתשעה, בעשרה, באחד עשר, בשנים עשר. לא פחות ולא יותר. כיצד? עצמו בתשעה. בחג, ביד אחד צלוחית של מים ⁠— הרי כאן עשרה.

Mishnah: The daily offering is sacrificed and its limbs are carried by 9 priests, as mentioned in a previous Mishnah. These 9 carry the limbs and the accompanying libations and meal-offerings. Occasionally, the service is performed by 10 priests, occasionally by 11, and sometimes by 12 priests; no fewer than 9 and no more than 12. How so? The daily offering itself is sacrificed by 9 priests, as explained earlier. On the festival of Sukkot a priest in whose hand is a jug of water for the water libation is added, and there are 10 priests. On Sukkot, a water libation is poured on the altar in addition to the standard wine libation.

בין הערבים באחד עשר: הוא עצמו בתשעה, ושנים בידם שני גזירי עצים. בשבת באחד עשר: הוא עצמו בתשעה, ושנים בידם שני בזיכי לבונה של לחם הפנים. ובשבת שבתוך החג ביד אחד צלוחית של מים.

In the daily afternoon offering, 11 priests participate in the service. How so? The daily offering itself is sacrificed by 9, and there are an additional two priests in whose hands are two logs that are placed on the altar. The mitzva of placing the two logs in the morning was assigned in the first lottery, as the Talmud explained earlier. On Shabbat, 11 priests participate. How so? The daily morning offering itself is performed by 9, and there are an additional two priests in whose hands are two vessels of frankincense that accompany the showbread. This frankincense is burned on Shabbat. And on Shabbat that occurs within the festival of Sukkot there is an additional priest in whose hand is a jug of water for the water libation, for a total of 12 priests.
