Our Parsha contains a passuk (verse) describing the inaugural Mincha offering as well as the daily Mincha offering, offered twice a day in perpetuity (6:13). If the offering is brought twice-daily, why do we need the added instructions of its being brought on the first day of service? Wouldn’t twice-daily be inclusive of the first time it’s offered?
Rav Moshe Feinstein extracts a meaningful lesson from this passuk. The kohen brings the same offering as his first day for every day of service to instill in him a sense of humility. While the kohen could easily get carried away with his status as a kohen, this daily mincha is an anchoring reminder that his service is a privilege not to be taken for granted. That initial gratitude of being in a position to contribute should be the prevailing attitude throughout our many roles in life.
