This week is Parashat Tzav as well as Shabbat HaGadol . On Shabbat HaGadol , the final Shabbat that the Jewish People were in Mitzrayim , Hashem commanded them to begin the process of offering the Korban Pesach . Why did Hashem command the Jews to take the sheep for the korban four days before they were going to offer it? The Midrash answers, the time of the Geula had arrived but the Jews did not have the merits to be redeemed so Hashem gave them an additional commandment regarding the korban to help them. Look how precious a mitzvah is! Even the preparation of the Korban Pesach was able to give the Jews the merit to be redeemed. The parshiot we are reading now are discussing the korbanot . The pasuk says when a Jew brought a korban, it was considered a ריח ניחוח לה' – it brought up a pleasing aroma to Hashem. What did Hashem love so much about a korban ? Perhaps we can explain from a question asked by the Acharonim : Why is it that the construction of the Mishkan did not override Shabbat while the offering of korbanot did? Seemingly, the building of a home for the Shechina to dwell in should be more important than offering sacrifices there. Rabbi Menashe Reizman quoted the sefer Nachat Yaakov who answered that the construction of the Mishkan was primarily done by Hashem. It was not humanly possible for a person to put it up, as the pasuk says הוקם המשכן. Many of the vessels as well were made by Hashem. The Menorah, for example, Hashem told Moshe to throw it into a fire and the Menorah came out. All the embroidery was miraculously made. Regarding the construction of the Second Beit HaMikdash, there were enormous stones, some 30 feet tall. How was it possible for a person to lift them so high upon a wall. The Yerushalmi says, when the people made the effort, Hashem miraculously lifted those stones for them. So therefore, since the Mishkan and the Beit HaMikdash were made by Hashem, although it was very important to Him, that did not override Shabbat. The korbanot , however, were performed exclusively by us. All of the difficult tasks involved in bringing a korban were done by the sweat of the people and Hashem loved their deeds so much. He loves when we put toil in to fulfill a mitzvah. That is what is so precious to Him and that even overrides Shabbat. Although today we cannot put in the same efforts of offering an actual korban , there's still a lot that we can do. The Midrash at the beginning of this week's parasha brings a mashal about a king who was traveling through the desert and his good friend came there to give him a basket of figs and a barrel of wine. The king told him, "You have honored me greatly by coming all the way here to give these thing to me." The friend replied, "My master, the King, this is just a small token of the honor that I want to give you. When you come back to your palace, you'll see there how much honor I'm really going to give you." That's the mashal. The nimshal is Hashem tells us, "זאת תורת העולה – You have honored Me by bringing a korban olah ." And we tell Hashem, "This is just a small token of the honor that we're capable of bringing You. When You come back to Your palace, there we're going to give You the real honor." This Midrash is obviously talking about today's time when we can't offer a real korban . So what temporary honor are we giving Hashem? Learning about the korbanot , drawing lessons from the korbanot . That in it of itself is so precious to Hashem and He considers it like we are honoring Him. But we tell Hashem, "Soon, when You bring back the Beit HaMikdash, there we're going to truly honor You, the way we're supposed to." As for today, we're still learning the lessons of korbanot , we're seeing how precious the nitty gritty involvement of a Jew in a mitzvah is to Hashem. We hope that just like Shabbat HaGadol was the last Shabbat for the Jews in Mitzrayim , so too it will be our last Shabbat in this long exile. B'ezrat Hashem, we should see the rebuilding of the Beit HaMikdash and be able to bring Hashem true glory inside of it. Shabbat Shalom.
