Talmud for Yevamot 84:8

HALAKHAH: ²²⁶This text is not only copied in Megillah, it exists in a slightly different text in Yebamot4:11 (Notes 172–175). Simeon bar Abba said, there came a case before Rebbi Joḥanan²²⁷Since the two texts are not identical, one cannot say that the instructions of R. Joḥanan reported here refer to the opinion of R. Yose in Yebamot. It was reported in the previous paragraph that R. Joḥanan was reluctant to declare Megillat Ta`anit as obsolete; here it is noted that he even endorsed the most restrictive version of the interpretations of the scroll. Since the following discussion is one about the principles of edition of Rebbi’s Mishnah, the implication is that R. Joḥanan’s objection is disregarded. and he instructed following Rebbi Yose. Rebbi Eleazar was sorry about this; he said, does one disregard the anonymous {Mishnah} and follow an isolated opinion²²⁸Since R. Joḥanan holds in general that the anonymous Mishnah is practice (Menaḥot52b).? He found that Rebbi Ḥiyya stated this in the name of Rebbi Meïr. When he understood that Rebbi Ḥiyya stated this in the name of Rebbi Meïr., he said, the old man²²⁹R. Joḥanan. understands his chapters well. Rebbi Mana asked before Rebbi Yudan: Did not Rebbi Ḥizqiah, Rebbi Abbahu say in the name of Rebbi Eleazar, every place where Rebbi taught a disagreement and afterwards taught it anonymously, practice follows the anonymous statement. He said to him, and if not Rebbi, maybe somebody else. How is this? If it is found that Rebbi taught a disagreement and afterwards taught it anonymously, then practice follows the anonymous statement. In a case where Rebbi did not teach a disagreement but others taught it in disagreement and Rebbi taught it anonymously, certainly practice has to follow the anonymous text. There come Rebbi Ḥizqiah, Rebbi Jacob bar Aḥa, Rebbi Simeon bar Abba, in the name of Rebbi Eleazar, every place where Rebbi taught a disagreement and afterwards taught it anonymously, practice follows the anonymous statement. Why does he instruct here following the isolated opinion? Rebbi Samuel bar Ina in the name of Rebbi Aḥa: That is, if no disagreement is stated together with the anonymous opinion. But if a disagreement is stated together with the anonymous opinion, practice does not follow the anonymous opinion. Rebbi Yose ben Rebbi Abun in the name of Rebbi Aḥa: that is if an individual disagrees with an individual. But in the case of an individual following the {anonymous} Sages, practice does not follow the anonymous text²³⁰The Babli (Yebamot42b, Bava qamma102a, Avodah zarah7a, Niddah11b) formulates the rule in the name of R. Joḥanan: Disagreement followed by anonymous statement, practice follows the anonymous statement. Anonymous statement followed by disagreement, practice does not follow the anonymous statement..
