Pesachim 52A

ביישוב לא עבידנא מפני שינוי המחלוקת. במדבר מאי? אמר ליה: הכי אמר רב אמי: ביישוב אסור, במדבר מותר.

we do not perform labor in the settled area due to the need to avoid deviation that causes dispute, as it is the custom in the Diaspora to refrain from performance of labor on those days. However, in the desert outside the Jewish community, what is the halakha? He said to him that this is what Rav Ami said: In a settled area it is prohibited; in the desert it is permitted.

רב נתן בר אסיא אזל מבי רב לפומבדיתא ביום טוב שני של עצרת. שמתיה רב יוסף. אמר ליה אביי: ולנגדיה מר נגידי! אמר ליה: עדיפא עבדי ליה, דבמערבא מימנו אנגידא דבר בי רב, ולא מימנו אשמתא.

Tangentially, it is reported that Rav Natan bar Asya relied upon his knowledge of the calendar and traveled from Rav’s study hall to Pumbedita on the 2nd day of the festival of Assembly, i.e., Shavuot, and thereby desecrated the 2nd day of the Festival by traveling beyond the town limits. Rav Yosef excommunicated him as punishment for this act. Abaye said to Rav Yosef: Let the Master flog Rav Natan bar Asya for this grave sin. Rav Yosef said to him: I punished him more severely, as in Eretz Yisrael they vote to flog a Torah scholar, but do not vote to punish him with excommunication, in deference to the Torah. Apparently, excommunication is a more severe punishment than lashes.

איכא דאמרי: נגדיה רב יוסף. אמר ליה אביי: נשמתיה מר, דרב ושמואל דאמרי תרוייהו מנדין על שני ימים טובים של גליות! אמר ליה: הני מילי ⁠— איניש דעלמא. הכא, צורבא מדרבנן הוא ⁠— דטבא ליה עבדי. דבמערבא מימנו אנגדתא דבר בי רב, ולא מימנו אשמתא.

Some say: Rav Yosef ordered the court officer to flog him. Abaye said to Rav Yosef: Let the Master excommunicate him, as it is Rav and Shmuel who both say that one excommunicates for desecration of the 2nd day of the Festival in the Diaspora. Rav Yosef said to him: That applies to an ordinary person. Here, he is a Torah scholar. I did what was best for him, as in Eretz Yisrael they vote to flog a Torah scholar but do not vote to punish him with excommunication. Rav Yosef did not wish to sentence him to so severe a punishment.
