The story of Kamtza and Bar Kamtza is perhaps the most well known rabbinic text associated with the destruction of the Second Temple. And yet, perhaps it’s our very familiarity with the episode which causes us to gloss over important subtleties embedded in the Talmudic account.
To recap, briefly: There was a man – never identified in the story – who threw a party and intended to invite his good friend Kamtza. His servant, however, erred and mistakenly invited his enemy, Bar Kamtza. When the host realized the mistake he immediately and very publicly demanded that Bar Kamtza leave the party. Obviously embarrassed, Bar Kamtza made a series of offers – even, ultimately, offering to pay for the entire party – hoping to persuade the host to allow him to remain. Unmoved, the host callously throws him out of the party. The Gemara recounts that Bar Kamtza was so offended, not only by the host, but also by the silence of the guests – some of whom were great rabbis – that he slandered the Jewish people to the Caesar. One thing leads to another and the result of this sad story is, ultimately, the destruction of the Beit Ha-Mikdash (Gittin 55b-56a).
The Talmud actually introduces the account by declaring that, “Yerushalayim was destroyed due to [the incident involving] Kamtza and Bar Kamtza.” In light of the actual unfolding of events, the inclusion of Kamtza in this incriminating statement is somewhat surprising. After all, Kamtza was not even at the party; he is no more than a “shadow figure” in this tragedy. What role did he play in this ignominious incident to deserve such apparent criticism?
R. Yosef Chayim of Baghdad (19th century, in his work, Ben Yehoyada) suggests that this is actually a misreading of the introductory phrase. The Talmud does not mean to criticize Kamtza, but rather included his name to teach us the larger lesson of the story.
