Page "Mishnah" Paragraph 27

Rabbi is credited with publishing the Mishnah, though there have been a few edits since his time ( for example, those passages that cite him or his grandson, Rabbi Yehuda Nesi ' ah ; in addition, the Mishnah at the end of Tractate Sotah refers to the period after Rabbi's death, which could not have been written by Rabbi himself ).

According to the Epistle of Sherira Gaon, after the tremendous upheaval caused by the destruction of the Temple and the Bar Kochba revolt, the Oral Torah was in danger of being forgotten.

It was for this reason that Rabbi chose to redact the Mishnah.
