Welcome to Embrace Shabbat.
When describing Shabbat in the Aseret HaDibrot (Parshat Yitro), the Torah says וַיָּ֖נַח בַּיּ֣וֹם הַשְּׁבִיעִ֑י, G-d rested on the seventh day. In his
sefer Be’er Moshe (Yitro 71), the Ozharover Rebbe points out that
the passuk should have said וְנַח בַּיּ֣וֹם הַשְּׁבִיעִ֑י, G-d rested on the seventh day. וַיָּ֖נַח literally means and He caused others to rest.
The Ozharover Rebbe quotes from the great mekubal Rav Yosef Gikatilla in his sefer Shaarei Orah. He explains that when a person keeps Shabbat properly, he turns into a “throne” for HaKadosh Baruch Hu. This is the meaning of וַיָּ֖נַח- G-d causes the Jewish people to rest when He rests His Name on them when they are shomer shabbat.
Similarly, the sefer Netivot Shalom explains that in our Shabbat prayers we say, לָקל אֲשֶׁר שָׁבַת מִכָּל הַמַּעֲשים, to G-d, Who rested from all of the creations. He explains, ביום השביעי נתעלה וישב על כסא כבודו- On the seventh day, G-d got up and He sat on His throne. נתעלה indicates that the Jewish people are uplifted on Shabbat, as they become “G-d’s throne” and G-d dwells on them.
Famously, Shabbat is referred to as מעין עולם הבא; Shabbat is likened to the World to Come. The pleasure that tzaddikim receive in the World to Come is that the shechina rests upon them. That is what similarly takes place in a microcosm on Shabbat.
In Tehillim (106:47), David HaMelech says, הוֹשִׁיעֵנוּ ה׳ אֱלֹקינוּ וְקַבְּצֵנוּ מִן־הַגוֹיִם לְהֹדוֹת לְשֵׁ֣ם קָדְשֶׁךָ לְהִשְׁתַּבֵּחַ בִּתְהִלָּתֶֽךָ׃, save us Hashem, and gather us from among the nations, to praise Your holy name, to give You glory with Your praise. In his commentary on Tehillim, Rav Chaim Kanievsky explains that the phrase לְהִשְׁתַּבֵּחַ בִּתְהִלָּתֶֽךָ is refering to the future. He quotes the Mabit (Beit Elokim, Shaar HaTefillah, Perek Bet) who says that in the future, there will be no prayers, as there will be no problems and no need to ask for anything. In the place of the requests will be pure shevach v’hodaah, praise.
הוֹשִׁיעֵנוּ ה׳ אֱלֹקינוּ וְקַבְּצֵנוּ
מִן־הַגוֹיִם- we ask Hashem to save us and gather us
from the goyim, לְהֹדוֹת לְשֵׁ֣ם קָדְשֶׁךָ, so that we only praise His Name in the World to Come. (We also pray
for this each morning in our Shacharit prayers). This connects beautifully to
the theme on Shabbat. As we know, there are no requests on Shabbat. Why?
Simply, when one requests something that is bothering them, it causes them
anguish. On a deeper level, Shabbat is מעין עולם
הבא; it is likened to Olam Haba, and therefore there are no problems on
Shabbat! It is all about מזמור שיר ליום השבת טוב
להודות לה. All we have to do on Shabbat is say thank
you, because we have no needs. That is Olam Haba- the shechina is here and it
is resting upon us. Tov l’hodot l’hashem.
Have a Shabbat Shalom.
