Remember that mishna I summarized last week, the first one of this tractate? The g'mara is still discussing it (not surprising, given its length). On today's daf the discussion turns to intercalating of years, the decision by a beit din to add a leap-month to the current year. The g'mara tells a story about a case of this and from it we learn lessons of humility:
The year can be intercalated only by a beit din appointed for that purpose. It once happened that Rabban Gamaliel had called for a court of seven to assemble early in the morning, but when he arrived he found eight people there. He asked the group: who has come without permission? Let him leave. Shmuel the Little said: I'm the extra; I didn't come to sit on the court but to learn the process. But Shmuel the Little wasn't the extra person; he spoke up to save the intruder from humiliation.
The g'mara tells another story of this kind of face-saving, this time about R. Meir. A woman came to his study hall and said: rabbi, one of you here has taken me to wife by cohabitation. R' Meir immediately arose and wrote her a get (a bill of divorce), after which every one of his disciples did likewise. And the g'mara says that he learned this from Shmuel the Little. (11a)
