Why would a Jew decide to become a nazirite? Naziriteship involves some significant sacrifices—a person who has taken the vow cannot cut his hair or drink wine—so, it’s natural to assume that it is an act of exceptional piety: You become a nazirite because you want to take up a heavy burden on God’s behalf. In Tractate Nedarim, however, the Talmud showed that people often took vows for less elevated reasons—out of pique or spite, or a rash desire to punish someone. And the same holds true, we learned this week in Tractate Nazir, of nazirite vows. Take, for instance, the rather odd scenario envisioned in Nazir 10a: “If one said: This cow said: I am hereby a nazirite if I stand up; or if he said: This door says: I am hereby a nazirite if I am opened, Beit Shammai say he is a nazirite, and Beit Hillel say he is not a nazirite.”
