"The entire community is holy and G-d is amongst them; why do you
raise yourselves above the congregation of G-d?" (Numbers 16:3)
Korach took 250 magistrates... and dressed them in garments that were wholly
of blue wool. They stood before Moses and asked him: "If a garment
is made entirely of blue wool, what is the law as regarding the obligation of tzitzit?"
Moses answered them: "It is obligated." They began to laugh at him, saying:
"If a garment of another sort is absolved by a single thread of blue wool, this garment,
composed wholly of blue wool, cannot absolve itself?"
Korach further challenged Moses: "If a house is full of Torah scrolls,
does it need a mezuzah on its doorpost?" Replied
Moses, "It is obligated." Said Korach: "The entire Torah,
consisting of 275 chapters, does not absolve this house, and the [two] chapters
in the mezuzah absolve it? G-d did not command you these laws -- you have
invented them yourself."
