Takanos of Chazal and the Gedolei HaDor
Similarly, the Zera Kodesh (Ki Seitzei תבנה כי ה"ד) writes, "Every day, when a Yid serves Hashem, he is building up Yerushalayim and the Beis HaMikdash. There is a person who builds an entire row, and there is another who might put up one brick. This is being done by every Yid who serves Hashem, until the Beis HaMikdash will be entirely built up."
Birchas Shalom of Ashlag zy'a, adds that bricks need cement. As it states (Shabbos 102b), "When one person places a brick and another person puts in the cement, the person who places the cement is chayav." The one who placed cement is the one who desecrated Shabbos because a brick, without cement, doesn't last. So, if our good deeds are like bricks that build the third Beis HaMikdash, what is the cement, and how do we bring this cement to the wall? The answer is that it’s the joy, chiyus, and hislahavus we have when we perform mitzvos. These connect us to the mitzvos, and connect the mitzvos with one another. This builds the Beis HaMikdash. May it be built speedily in our days.
Takanos of Chazal and the Gedolei HaDor
(30:2) זֶה לֵאמֹר יִשְׂרָאֵל לִבְנֵי הַמַּט ּוֹת רָאשֵׁי אֶל ֶׁהמֹש וַיְד ַבֵּר 'ה צִוָּה ֶׁראֲש ה ַדָּבָר , " Moshe spoke to the heads of the tribes of Bnei Yisrael, saying: "This is the thing Hashem has commanded."
The question is why it doesn't state וידבר לאמר משה אל 'ה at the beginning of this parashah, as it generally does?
Sefer HaChaim (from the brother of the Maharal of Prague zt'l) explains, "This is to teach us that the takanos that the heads of Bnei Yisrael establish as a סייג, a gate, when the times and the needs require it, are also 'ה צִוָּה ֶׁראֲש ה ַדָּבָר, Hashem's command. "
In other words, Moshe told Bnei Yisrael that when the יִשְׂרָאֵל לִבְנֵי הַמַּט ּוֹת רָאשֵׁי, leaders of Bnei Yisrael, of each generation, establish takanos and gedarim to protect the holiness of Klal Yisrael, it is as if they were commanded from Hashem, Himself to keep these safeguards, and we are obligated to keep them.
Similarly, the Chasam Sofer zt'l writes, "Moshe told Bnei Yisrael regarding the רָאשֵׁי הַמַּט ּוֹת, the leaders of Bnei Yisrael. The Jewish nation should consider their decrees as זֶה 'ה צִוָּה ֶׁראֲש ה ַדָּבָר, Hashem's command... מסתמא כי קדשים צאן ברועה נוססה 'ה רוח, We can assume that Hashem's spirit is within the leaders of the holy Jewish nation," and when they make a decree, it was inspired by Hashem. Therefore, we must uphold their takanos and gedarim.
