בָּנִ֣ים אַתֶּ֔ם לַֽיהוָ֖ה אֱלֹהֵיכֶ֑ם לֹ֣א תִתְגֹּֽדְד֗וּ וְלֹֽא־תָשִׂ֧ימוּ קָרְחָ֛ה בֵּ֥ין עֵינֵיכֶ֖ם לָמֵֽת׃
너희는 너희 하나님 여호와의 자녀니 죽은 자를 위하여 자기 몸을 베지 말며 눈썹 사이 이마 위의 털을 밀지 말라
Jerusalem Talmud Pesachim
Rebbi Simeon ben Laqish asked Rebbi Joḥanan: Is it not forbidden because of “do not split into sects”53How can the Mishnah require people who move from place to place to follow the more restrictive practice? Does this not violate the basic principle of uniform practice based on an aggadic interpretation of Deut. 14:1. Babli Yebamot 13b.? He said to him54He wants to restrict the prohibition of concurrent different practices to cases of fundamental differences in the formulation of rules, not to differing interpretations of existing rules., in case these follow the House of Shammai and those the House of Hillel. But between the House of Shammai and the House of Hillel does practice not follow the House of Hillel55The answer is unsatisfactory since in post-Jabneh Judaism, practices of the House of Shammai are not recognized anyhow.? He said to him, in case these follow Rebbi Meïr and those follow Rebbi Yose. But between Rebbi Meïr and Rebbi Yose, does practice not follow Rebbi Yose? He answered him, there are two Tannaim regarding Rebbi Meïr and two Tannaim regarding Rebbi Yose56While it is agreed as general rule that between R. Meïr and R. Yose practice follows R. Yose (Maˋserot 1:7 Note 200; Babli Eruvin 46b), this is only a general rule, not an invariable principle. There are many examples where other Tannaim follow the lines of argument of R. Meïr and R. Yose and practice was decided only in later generations.. He said to him, is there not New Year’s Day and the Day of Atonement, where in Judea one used to follow Rebbi Aqiba and in Galilee Rebbi Joḥanan ben Nuri57Mishnah Roš Haššanah 4:6,7 explains their differences in the way prayers and shofar blowings are combined on New Year’s day and the Day of Atonement in a Yovel year.. He told him, there is a difference since if he changed and in Judea acted as in Galilee or in Galilee as in Judea he discharged his obligation58Everybody will agree that either way fulfills the biblical requirement.. But is there not Purim, where these read on the fourteenth and those on the fifteenth59Days of reading of the Esther scroll in the month of Adar. Since the date of reading is determined by the place of reading, it is obvious that a visitor has to read with the local people.? He told him, he who edited the Mishnah based it on Scripture60Esth. 9:28. Since the differences are of biblical origin, the example is irrelevant for the rabbinic prohibition.: Family and family, country and country, and town and town.
