אַתֶּם נִצָּבִים הַיּוֹם כֻּלְּכֶם לִפְנֵי ה' אֱלֹקֵיכֶם: (כ"ט ט')
You are all standing this day before Hashem, your G-d. (29:9) The Zohar Hakadosh explains “this day” as Rosh Hashanah. All that was unfolding that day refers to the day of reckoning when all creatures pass through Hashem, and He decrees who will live and prosper. The terrifying of Tefilas Unesane Tokef which details how the angels are petrified and running back and forth from fear. Which of course the angels don’t really sin, yet they are afraid. This should be enough for a simple creature, who cannot say that he is clean from sin. Therefore, Hashem with his great kindness gives us a chance to do Teshuva, and pray, and give tzedaka, and these three acts will override any harsh decrees.
A unique event in human history took place when this posuk was delivered by Moshe: the entire membership of Klal Yisroel were assembled before the Creator. But just what did this act of "standing" entail, beyond confirming and binding them to the Covenant? The Toldos Yaakov Yosef, by way of a parable which he himself heard from the mouth of the Holy Ba'al Shem Tov, his Rebbe, commented on a posuk from Tehillim (102:1) תְּפִלָּה לְעָנִי כִי־יַעֲטֹף וְלִפְנֵי ה' יִשְׁפֹּךְ שִׂיחוֹ A prayer for a poor man when he enwraps himself and pours out his speech before Hashem. A King once made a celebration and promised his subjects that they each could request one favour from him, and it would be granted. One very wise man stood out from the others; he asked that he be able to converse with the king three times a day. This astute request pleased the king so much that not only did he grant the request, but went beyond it and gave the wise man gifts which he had not even requested. So it is with Hashem and the Yidden: Hashem listens to the prayer of the humble Yid תְּפִלָּה לְעָנִי כִי יַעֲטֹף, standing "enwrapped in his tallis", when he is standing upright before Hashem, pouring out his heartfelt needs, "three times a day" לִפְנֵי ה' יִשְׁפֹּךְ שִׂיחוֹ. These are the words of the Holy Ba'al Shem Tov. Now to our posuk: How does a Yid become נִצָּבִים upright? By having his prayers answered! This accomplishment is only לִפְנֵי ה' אֱלֹקֵיכֶם when he sees himself always standing in Hashem's presence, graciously allowed to make any request. (תולדות יעקב יוסף). The Chovas Halevavos elaborates on the subject of being close to Hashem. Since Hashem has the traits and abilities beyond what one can imagine, in His wealth or strength, by being close to Hashem there is an open door to anything one would want. Loving a fellow Yid is a connection to loving Hashem and getting close to Him.
