The word o,rzvu, you shall separate, from contamination is derived from the word rzb, crown. The crown distinguishes its wearer from the masses. The Sfas Emes explains, that similarly, Bnei Yisrael distinguish themselves by separating from the moral contaminants which abound. It is the true hallmark of Bnei Yisrael’s majesty that they rise above earthly contamination in order to devote themselves to serving Hashem. Those who dedicate their lives to this endeavor are truly worthy of Hashem’s crown.
