Rashi explains that the vestments should fit correctly on the Kohen. If they are either too long or too short, they are inappropriate for ritual purposes. Horav M. Sternbuch, Shlita, suggests that this concept also applies to other areas of spiritual endeavor. The external garment should be suitable and consistent with the stature of its wearer. The Rambam states that those designated elite who dedicate their entire life to Torah study are included as honorary members of the tribe of Levi. Their devoted service to Hashem represents the loftiest pursuit, parallel to the dedication of the Leviim.
Therefore, the Torah scholar should be cognizant of his manner of dress. He should refrain from clothing himself in inappropriate attire. His outer garments and grooming should be in consonance with his station in life. Clothing himself in apparel not worthy of his position creates a chillul Hashem. Dressing in an arrogant manner demonstrates a haughtiness which is the result of insecurity and diffidence.
We may advance this idea further. Every individual has his own unique characteristics. Consequently, each individual is best suited for those particular positions in life in which he can realize his greatest potential. When someone rejects his own potential by pursuing a profession removed from his stronger qualities, he is denying his G-d-given direction. This could harm the individual, as well as those around him.
People should seek to develop their individual personality to its fullest extent. They should be careful not to assume another’s role. Kohanim have a predetermined occupation for which they are specifically suited, as a result of their descendance from Aharon Ha’kohen. They are charged to “clothe themselves” in the attire befitting them by remaining dedicated to their Heavenly ordained vocation.
Horav Sternbuch states that the word sc is closely related to the word sckw which means “alone.” This alludes to the talmid chacham’s mission. He stands alone. He should be aware of the Torah’s demands upon him and not allow himself to be influenced by those who seek to alter his opinion on a given matter. He must remain resolute and uncompromising in his commitment to Hashem and His Torah.
