Olat Shabbat B’ShabbatoThe Sacrifice of each Shabbat must be offered on that Shabbat.
The Medrash explains that I might have thought that all Shabbatot are the same, and if I miss bringing the sacrifice this week then I’ll just bring it next week. The verse comes to teach us Olat Shabbat BeShabbato- there is no make up.
As the Siftei Chachamim explains, every Shabbat is a unique gift. We may seem to do the same things each week, but in fact any given Shabbat can never be replicated.
Although we no longer offer sacrifices today, this Midrashic idea finds expression today in the halachot of the Mussaf prayer that we recite each Shabbat. The Halacha is that if you miss one of the prayer services, you can make it up by saying two Amidas the next time (miss Shacharit, say two Minchas, etc). This is called Tashlumin, based on the "make-up" possibility that existed by certain korbanot. However, the Halacha is that there is no Tashlumin for Mussaf. Once Shabbat ends, there is no makeup. Not Sunday, not the next Shabbat. I missed out and I have to live with that fact.
Judaism believes strongly in second chances: sometimes referred to as teshuva. But the Korban Mussaf in this morning’s Parsha reminds us that contrary to popular belief, there are some things in life that cannot be replicated, cannot be made up, and if you miss them you’re out of luck.
This is especially relevant with the moments of our life. Time can never be made up (even for drivers who speed the last half of their trip to "make up the time".) We can’t go back in time. (we have yet to discover the flux capacter or generate 1.21 jigawatts). Each moment is unique, each Shabbat is unique. With the help of the lessons of Korban Mussaf – Olat Shabbat B’Shabbato- let us better appreciate those things in life that cannot be replicated.
