1you are not allowed to permit these actions in their presence, lest they come to treat other prohibitions lightly, saying: If this previously prohibited activity was permitted, other prohibitions are not particularly stringent either. How did Rav Yosef permit the residents of Ḥozai to eat rice dough? Rav Yosef said to Abaye: And wasn’t it stated about this halakha concerning stringencies that Rav Ḥisda said: This was stated specifically with regard to Samaritans? The Gemara rejects this: What is the reason that this applies to Samaritans? It is due to the fact that they will extend this matter of leniency, and add to it additional, unjustified leniencies. These people of Ḥozai will also extend this matter of leniency, and come to practice additional leniencies in other cases, as they are ignoramuses.
2Rather, Rav Ashi said: We see, if the majority of people in that place eat rice, do not let a non-priest eat ḥalla in their presence, lest the halakhic category of ḥalla be forgotten from them. And if most of them eat grain, let a non-priest eat ḥalla separated from rice dough in their presence, lest they separate ḥalla from grain, from which separating ḥalla is a requirement, on behalf of rice from which separating ḥalla is an exemption, in which case the priest eating the ḥalla would be eating bread from which ḥalla was not separated; or from that which is an exemption on behalf of that which is a requirement, in which case the person eating the grain bread would be eating bread from which ḥalla was not separated.
3After mentioning halakhot relating to customs, the Gemara returns to discuss the matter itself. If matters are permitted but others were accustomed to treat them as a prohibition, you are not allowed to permit these actions in their presence. Rav Ḥisda said: We are dealing with Samaritans, not with Jews. The Gemara is surprised at this: And doesn’t this apply to everyone? Wasn’t it taught in a baraita to the contrary? Two brothers may bathe together, and there is no concern that doing so is immodest or will lead to sinful thoughts. However, the custom was that two brothers do not bathe together in the city of Kabul (see I Kings 9:13). And there was an incident involving Yehuda and Hillel, sons of Rabban Gamliel, who bathed together in Kabul, and the entire city denounced them and said: In all our days we have never seen that type of conduct. Hillel stole away and went out to the outer chamber and did not want to tell them: You are permitted to do so. He preferred to obey the city residents rather than rule it permitted for two brothers to bathe together.
4Similarly, one may go out with wide shoes that resemble slippers on Shabbat; however, one does not go out with wide shoes in the city of Birei. And there was an incident involving Yehuda and Hillel, sons of Rabban Gamliel, who went out with wide shoes in Birei, and the people of the city denounced them and said: In all our days we have never seen that type of conduct. And Yehuda and Hillel removed their shoes, and gave them to their gentile servants, and did not want to tell the residents of the city: You are permitted to go out with wide shoes on Shabbat.
5Similarly, one may sit on gentiles’ stools on Shabbat, even though these stools are typically used for displaying merchandise. But one may not sit on gentiles' stools on Shabbat in the city of Akko. And there was an incident involving Rabban Shimon ben Gamliel who sat on gentiles’ stools on Shabbat in the city of Akko, and the entire city denounced him. They said: In all our days we have never seen that type of conduct. Rabban Shimon ben Gamliel moved onto the ground and did not want to tell them: You are permitted to sit on the stools. The Gemara answers: The legal status of people in the cities, since Sages are not found among them, is like that of the Samaritans. Therefore, it is prohibited to tell them that these activities are permitted.
6The Gemara proceeds to clarify the reasons for the stringent customs in those communities. Granted, sitting on gentiles’ stools is prohibited because it appears like one is engaged in buying and selling on Shabbat. In the case of wide shoes as well, it is prohibited to wear them due to the concern lest they fall off one’s feet and he come to carry them in his hand four cubits in the public domain, thereby violating a Torah prohibition.
7However, what is the reason that two brothers may not bathe together? The Gemara answers: The custom to prohibit doing so is based on that which was taught in a baraita : A person may bathe with anyone except for his father, and his father-in-law, and his mother’s husband, and his sister’s husband. Due to the nature of their relation, one might come to ponder how they came to be related and have prohibited thoughts about intimacy between men and women. And Rabbi Yehuda permits one to bathe with his father, due to the honor that he can accord his father by assisting his father while bathing. The same is true for one’s mother’s husband.
8And the people of Kabul came and issued a decree to prohibit bathing together for two brothers, due to their concern that it is similar to bathing with one’s sister’s husband. It was taught in the Tosefta : A student may not bathe with his teacher, since it is disrespectful to see one’s teacher naked. But if his teacher requires his help when bathing, it is permitted.
9The Gemara relates: When Rabba bar bar Ḥana came from Eretz Yisrael to Babylonia, he ate the fat found over the straight part of an animal’s stomach. The fat along the stomach consists of two parts: The inner, straight portion, which is shaped like a bowstring, and the outer, rounded portion, which is shaped like a bow. With regard to the fat surrounding the inner, straight portion, the custom in Eretz Yisrael was lenient, whereas in Babylonia it was stringent. Rav Avira the Elder and Rabba, son of Rav Huna, entered to see Rabba bar bar Ḥana. When he saw them coming, he concealed from them what he was eating. They came and told Abaye what had happened, and he said to them: Through his conduct, he rendered you Samaritans, as he could have told you that it is permitted but did not do so.
10The Gemara asks: And is Rabba bar bar Ḥana , who was lenient with regard to a matter that is prohibited, not in agreement with that which we learned in the mishna: When one travels from one place to another, the Sages impose upon him the stringencies of the place from which he left and the stringencies of the place to which he went? Abaye said: That applies when one travels from one place in Babylonia to another place in Babylonia, or from one place in Eretz Yisrael to another place in Eretz Yisrael, or alternatively, from Babylonia to Eretz Yisrael. However, when traveling from Eretz Yisrael to Babylonia, no, this principle does not apply. Since we, the residents of Babylonia, are subordinate to them in terms of halakha , we act in accordance with their custom, but a resident of Eretz Yisrael is not required to follow the Babylonian custom.
11Rav Ashi said: Even if you say that when one travels from Eretz Yisrael to Babylonia, he is required to act stringently in accordance with the local custom, this applies only when his intent is not to return. One is required to adopt the local customs when permanently settling in a new location. However, as Rabba bar bar Ḥana’s intent was to return to Eretz Yisrael, his point of origin, he continued to follow the custom of Eretz Yisrael. The Gemara relates that Rabba bar bar Ḥana said to his son: My son, you live in Babylonia. Therefore, do not eat this fat, neither when you are in my presence nor when you are not in my presence. I, who saw Rabbi Yoḥanan eat this fat, can say that Rabbi Yoḥanan is worthy for one to rely upon him both in his presence and not in his presence. You did not see him. Therefore, do not eat it, neither when you are in my presence nor when you are not in my presence, since you may not rely upon my opinion alone in this matter.
12The Gemara comments: And this statement of his disagrees with another statement of his, as Rabba bar bar Ḥana said: Rabbi Yoḥanan ben Elazar told me: Once I followed Rabbi Shimon ben Rabbi Yosei ben Lakonya into the garden next to his house,
