25. One verse says, "Serve Hashem with gladness" (Tehilim 100:2), and one says, "Serve Hashem with fear, and rejoice with trembling" (Tehilim 2:11). What is the difference between them? HE ANSWERS: One speaks of the time when Yisrael live in the Holy Land, THAT IS, WHEN THEY SERVE HASHEM HAPPILY, and one speaks of a time when Yisrael live in other lands - THEN IT IS NECESSARY TO SERVE HASHEM IN FEAR AND REJOICE WHILE TREMBLING. "Serve Hashem with fear." This refers to the Congregation of Yisrael, NAMELY MALCHUT at a time when she is in exile among the nations.
25. כָּתוּב אֶחָד אוֹמֵר, עִבְדוּ אֶת יְיָ' בְּשִׂמְחָה, וְכָתוּב אֶחָד אוֹמֵר, עִבְדוּ אֶת יְיָ' בְּיִרְאָה וְגִילוּ בִּרְעָדָה. מַה בֵּין הַאי לְהַאי. אֶלָּא, כָּאן בְּזִמְנָא דְּיִשְׂרָאֵל שָׁרָאן בְּאַרְעָא קַדִּישָׁא. כָּאן בְּזִמְנָא דְּיִשְׂרָאֵל שָׁרָאן בְּאַרְעָא אַחֲרָא. עִבְדוּ אֶת יְיָ' בְּיִרְאָה, דָּא כ"י, בְּזִמְנָא דְּאִיהִי בְּגָלוּתָא בֵּינֵי עֲמַמְיָא.
