Zevachim 120A

שהכניסה לפנים והוציאה לחוץ ⁠– מהו? מי אמרינן: כיון דעיילא ⁠– קלטה לה מחיצתא; או דלמא, כיון דהדר ⁠– הדר?

that one brought inside and subsequently took outside, what is the halakha? Does it have the status of a sacrificial item of a public altar? The Talmud clarifies the question: Do we say that once it was brought in the partition has already absorbed it, and all halakhot of sacrificial items of a public altar apply; or perhaps once it returns, i.e., was taken outside again, it returns to its prior status as an offering of a private altar?

לאו היינו פלוגתא דרבה ורב יוסף? דתנן: קדשי קדשים ששחטן בדרום ⁠– מועלין בהן, ואם עלו לא ירדו.

The Talmud asks: Isn’t this issue a disagreement between Rabba and Rav Yosef? As we learned in a Mishnah (Me’ila 2a): With regard to offerings of the most sacred order, e.g., a sin offering or a guilt offering, that were slaughtered in the south of the Temple courtyard, and not in the north as dictated by halakha, and are therefore disqualified, one who derives benefit from them is liable for misuse of consecrated property, and despite the fact that they should not ascend the altar, if they ascended they should not descend.

ואיבעיא להו: ירדו, מהו שיעלו? רבה אמר: לא יעלו, ורב יוסף אמר: יעלו.

And a dilemma was raised before the rabbis: If they did descend the altar, what is the halakha with regard to ascending again? Rabba says: They should not ascend, and Rav Yosef says: They should ascend. Consequently, they disagree with regard to the issue of whether an item that is not fit to be sacrificed in a consecrated area acquires the sanctity of that area even if it is removed from there.

תיבעי לרבה, תיבעי לרב יוסף. תיבעי לרבה: עד כאן לא קאמר רבה ⁠– אלא במזבח; דחזי ליה מקדש, דלא חזי לא מקדש; אבל מחיצה, אף על גב דלא חזי ליה ⁠– קלטה.

The Talmud responds: The disagreements are not identical, as the dilemma can be raised according to the opinion of Rabba, and the dilemma can be raised according to the opinion of Rav Yosef. The Talmud elaborates: It is possible to raise the dilemma according to the opinion of Rabba, as Rabba says his statement: Offerings of the most sacred order that were slaughtered in the south should not descend if they ascended, only with regard to the altar, as the altar consecrates that which is fit for it, while it does not consecrate that which is not fit for it. But with regard to the partition of the public altar, even though an offering that was consecrated for a private altar is not fit for that altar, the partition nevertheless absorbs the offering and it is sacrificed there. Consequently, all the halakhot of the public altar apply to that offering, even if it is taken outside.
