רבינו בחיי — ויקח קרח

Q — Korach's tzitzis-and-mezuzah questions to Moshe (talis kulah techeles, bayis maleh sefarim) look like clever halachic gotchas. What was he really arguing?

A — Rabbeinu Bachya unmasks the questions as parables for a hashkafic platform — an anti-hierarchy manifesto dressed as halacha. The tallis kulo techeles is a moshol for Klal Yisrael, every one of whom is already kadosh ("כי כל העדה כלם קדושים"). The bayis maleh sefarim is a moshol for a community already saturated with Torah. The chut shel techeles and the mezuzah, in this reading, stand for *leaders*: the small piece of distinguishing-blue, the discrete kedushah-marker added to an otherwise ordinary thing. Korach's argument: when the whole nation is already a tallis kulo techeles, why graft on a smaller patch of techeles? When the bayis is already full of seforim, why add a mezuzah? That is, when Klal Yisrael is already kadosh, why need a Moshe and an Aharon? Korach's questions are not legal sophistry but a serious populist case for the abolition of hierarchy — and that, RBB shows, is why they had to be answered not by halachic counter-arguments but by ground splitting open.
