Eruvin 99A

הוא סבר: מדסיפא רבי מאיר, רישא נמי רבי מאיר. ולא היא: סיפא רבי מאיר, ורישא רבנן.

The Talmud explains: Rav Ḥinnana maintains that from the fact that the latter clause of the Mishnah, was taught in accordance with the opinion of R' Meir, it can be inferred that the first clause was likewise taught in accordance with the opinion of R' Meir. But in fact that is not so: The latter clause is in accordance with the opinion of R' Meir, while the first clause is in accordance with that of the Rabbis.

ובלבד שלא יוציא חוץ. הא הוציא חייב חטאת. לימא מסייע ליה לרבא, דאמר רבא: המעביר חפץ מתחילת ארבע לסוף ארבע, והעבירו דרך עליו ⁠— חייב.

We learned in the Mishnah: One may move objects in a public domain when he is standing in a private domain, provided that he does not carry them beyond 4 cubits in the public domain. The Talmud infers: This teaching indicates that if he carried them beyond 4 cubits, he is liable to bring a sin-offering. The Talmud asks: Let us say that this ruling supports the opinion of Rava, as Rava said: With regard to one who carries an object in a public domain from the beginning of 4 cubits to the end of those 4 cubits, even if he carried it above his head, i.e., he lifted the object above his head so that it passed through an exempt place, he is nonetheless liable for carrying 4 cubits in a public domain. Here, too, although he is standing in an elevated private domain and carries the object at that elevated height, he is still liable.

מי קתני: אם הוציא חייב חטאת? דילמא אם הוציא ⁠— פטור אבל אסור.

The Talmud rejects this contention: Is the Mishnah teaching that if he carried the object beyond 4 cubits he is liable to bring a sin-offering? Perhaps the Mishnah means: If he carried the object beyond 4 cubits, he is exempt from bringing a sin-offering, but it is nevertheless prohibited by rabbinic decree to do so.
