parshat Korach

When we are commanded about wearing tzitzis, the Torah includes two mitzvos. In addition to the mitzvah of wearing tzitzis threads on the corners of the garment, there is an additional mitzvah that some of the tzitzis threads should be dyed with a special dye called techeiles. (There is a dispute among the Rishonim how many of the tzitzis threads are to be dyed techeiles.) This dye must be made from a species called chilazon (Tosefta Menachos 9:6).

Why do the Jewish people have to be pigeon-holed into various classes? Isn't equality the key to unity?

In Josephus' description of what happened after the destruction, he talks about the thickness of the stones in Jerusalem and the difficulty of destroying them. "I would never have been able to breach these walls if it wasn't for the Jews fighting among themselves and the disputes between them." About the unlimited power we can attain and about the havoc that controversy can cause.
