The Kohen Gadol is finally prepared to appear before Hashem to implore His atonement on behalf of Klal Yisrael. He has said his Viddui and slaughtered his personal Korban Chatas. He is now ready to offer the Ketores, incense, in the Kodesh Ha’kodoshim. The Kohen Gadol enters the Holy of Holies once a year, on Yom Kippur. The first service he performs, the first request he makes of the Al-mighty, is to seek atonement for the sin of lashon hora, speaking gossip and slander.
The Ketores serves as the vehicle for this request. How does the offering of the finely ground incense-spices symbolize lashon hora? Horav David Feinstein, Shlita, offers an insightful explanation. He quotes Rashi, who, in citing the interpretation of Chazal, questions the need for emphasizing that the incense-spices were finely ground. Ketores was brought every day in the Bais Ha’mikdash, and it was finely ground. Why should it be different on Yom Kippur? Chazal conclude that while it is mandatory to finely grind the spices during the year, on Yom Kippur it is essential that they be exceptionally fine. Consequently, the spices are ground again on the day before Yom Kippur.
Ketores was offered twice daily, in the morning and in the afternoon. These offerings served to atone for the sin of lashon hora. The recurrence of this sin is noted by the twice daily offering of Ketores. On Yom Kippur, something more than the average Ketores was needed. On this day, when Klal Yisrael must receive atonement for all sins, it was essential that focus be brought on the form of lashon hora that is the most subtle and most common–avak lashon hora, dust of lashon hora. This “innocuous” form of lashon hora is like fine dust, very elusive, at times even sophisticated and well-meaning, but lashon hora no less. It affects the majority of people. Thus, Klal Yisrael must atone for it on the day when everyone stands in prayer begging for forgiveness.
Avak lashon hora is the source of most sin. Many sins begin with a simple derogatory remark about someone which becomes magnified over time. This “humble” beginning can lead to the most unspeakable forms of behavior. It is, therefore, especially appropriate that we grind up the incense a second time, so that we make it as fine as possible, symbolizing the “fine dust” of lashon hora.
