Zevachim Daf 86 זבחים דַף 86

The Mishnah on the previous Daf lists items which, even if they were placed on the מזבח, must be brought down: any kodashim which is supposed to be eaten (e.g., meat of most korbanos), and the קטורת (which is only fit for the מזבח הפנימי). Regarding wool from a lamb’s head, or hair of a goat’s beard, והעצמות והגידים והקרנים והטלפים – and the bones, sinews, horns, and hooves, if they are attached to the korban, they are brought onto the מזבח with it. פירשו – If they separated from the korban, לא יעלו – they are not brought up. A Baraisa relates a machlokes about this question: the Tanna Kamma says והקטיר הכהן את הכל המזבחה – and the Kohen shall burn everything on the mizbeiach includes עצמות, גידין, etc. to be burned on the מזבח, even if they did separate, and the passuk ועשית עולותיך הבשר והדם – and you shall make your olos, the meat and the blood (implying no other items) teaches to only return עיכולי עולה – consumed parts of an olah to the מזבח, and not consumed bones, sinews, etc. Rebbe holds the opposing implications of the two pesukim teach that attached bones, etc. are brought up with the korban, and detached ones are not brought up, like the Mishnah holds.

The next Mishnah states that if any of the items mentioned earlier (i.e., invalidated אימורין, or bones, etc.) burst off the top of the מזבח, they do not need to be returned there. The same applies to a גחלת – ember of burnt wood. איברים שפקעו מעל גבי המזבח – Limbs of valid korbanos which burst off the top of the מזבח, קודם חצות יחזיר – before midnight, they should be returned, and are still subject to me’ilah, since they must still be burned. After חצות, they must be returned, and are exempt from me’ilah. The Gemara clarifies that אברים which still have ממש – substance must be returned even after חצות, and those without substance are not returned even before חצות. The Mishnah’s distinction is relevant for שרירי – limbs which have hardened like wood, but have not become charcoal. Rav explains: one passuk implies that הקטרה – burning takes place the entire night, while another implies that הרמה – separating the ashes occurs any time during the night, indicating that anything on the fire is considered fully burned and eligible for תרומת הדשן. Therefore, we say: חלקיהו חציו להקטרה וחציו להרמה – divide [the night]; half of it is for burning, and half of it is for separating ashes.

Rav implied that תרומת הדשן cannot take place before חצות. This is challenged from a Mishnah, which states that during the year, תרומת הדשן is performed מקרות הגבר – from the call of the rooster (just before the day). On Yom Kippur, this was done at חצות, and on רגלים, it was done באשמורת הראשונה – at the first watch (i.e., the first third of the night). According to Rav, that תרומת הדשן cannot take place before חצות, how was it performed earlier on רגלים? Rebbe Yochanan answers that since the passuk implies that הקטרה takes place the entire night, the words "עד [ה]בקר" – until the morning are superfluous, and teach: תן בקר לבקרו של לילה – give another “morning” to the morning which is at the end of the night, i.e., perform תרומת הדשן of real ashes before the morning (whereas Rav discussed שרירי – hardened limbs). Since this time is undefined, the Sages designated times based on that day’s needs. Thus, during the year, it may be done just before the morning. On Yom Kippur, it is done at midnight, משום חולשא דכהן גדול – because of the weakness of the Kohen Gadol, who had to perform all the day’s avodah himself. On רגלים, when there were many korbanos, it was performed earlier in the night.
