There’s several stories (that I know of) which deal with Rabban Gamliel acting in a less-than-ideal way in regard to his contemporaries:
- Rosh HaShanah 25a-b, where Rabban Gamliel insisted that R’ Yehoshua violate Yom Kippur according to his own calculations and defer to that of the court
- Bechoros 36a, where Rabban Gamliel publicly humiliated R’ Yehoshua in response to his contradictory ruling regarding R’ Tzadok’s firstborn animal
- Berachos 27b-28a, where Rabban Gamliel publicly humiliated R’ Yehoshua in response to his contradictory ruling regarding Maariv being obligatory or not, and which also deals with the aftermath of this and the above two incidents, in which Rabban Gamliel was temporarily deposed from his office
- Bava Metzi’a 59b, where Rabban Gamliel has his brother-in-law R’ Eliezer excommunicated for arguing against the majority; ultimately R’ Eliezer’s tefillos inadvertently led to Rabban Gamliel’s early death
Is there any indication as to the chronological order of these stories? (Obviously Rabban Gamliel’s death in Bava Metzi’a happened last, but it’s possible that the excommunication happened before any of the other incidents cited here.)
As I’ve said previously, it seems to me that the first three incidents cited took place before the other two, as Berachos only records those two incidents as prompting Rabban Gamliel’s being deposed, leaving out the latter incident. Given that both deal with R’ Yehoshua, and the conclusion of the story in Bechoros is repeated in the story in Berachos, it’s possible that all three of these happened simultaneously.
Perhaps Berachos only cites Rosh HaShanah and Bechoros (and itself) as those were the immediate triggers, but there had been a history of perceived abuse of the position by Rabban Gamliel before then?
(Feel free to edit in other stories that I missed, but I think these are all of them.)
