רַבֵּנוּ הַזָּקֵן אָמַר: מִצְוַת אַהֲבַת יִשְׂרָאֵל הוּא לִיְלִיד עַם יִשְׂרָאֵל אֲשֶׁר מֵעוֹלָם לֹא רָאָה אוֹתוֹ, וּמִכָּל שֶׁכֵּן לַחֲבֵר עַדַת יִשְׂרָאֵל אֲשֶׁר בִּמְקוֹם מְגוּרוֹ, שֶׁהוּא בֶּן אוֹ בַּת עֲדָתוֹ.
The Alter Rebbe taught that the mitzvah of ahavas Yisrael, loving a fellow Jew, applies to every member of the Jewish people, even if one has never seen him. How much more does it apply to a member of the Jewish neighborhood in which one lives, to every man or woman who is a member of one’s own community.1
Delving Deeply
Paradoxically, the second part of this teaching often proves more difficult to fulfill than the first. It is easier to love people whom we barely know, because our relationship with them is so transient. We do them a favor and they are gone. By contrast, a much stronger commitment is required in order to show love and concern to someone we see on a daily basis. This indeed is the challenge.
Was the second Beit HaMikdash dedicated on the 3rd of Adar I, or Adar II, 3412?
Source?
The source for the date of the completion of the Beis Hamikdash is Ezra 6:15: "The house was finished on the third of the month of Adar." The verse does not specify. That implies that the year was not a leap year, and it was the only Adar that year. The Malbim also believed that, writing that the construction took 4 years and six months. The construction began at the end of Elul (Chagai 1 :15). So, it must have been either the only Adar, or Adar 1.
So, why chabad.org does not mention it on the 3rd of Adar I (but does on 3rd of Adar II)?
BTW, according to the currently used fixed callendar, the year 3412 would had two Adars.
