The Gemara states that Rav Yehuda maintains that the day when it rains is equal to the day that the Torah was given, as it is said (Devarim 32:2) יַעֲרֹף כַּמָּטָר לִקְחִי, may my teaching drop like rain, and the word לִקְחִי alludes to Torah, as it is said (Mishlei 4:2) כִּי לֶקַח טוֹב נָתַתִּי לָכֶם תּוֹרָתִי אַל תַּעֲזֹבוּ, for I have given you a good teaching, do not forsake My Torah. Rava, however, posits that the day when it rains is even greater than the day the Torah was given, as it is said יַעֲרֹף כַּמָּטָר לִקְחִי, and we see that Scripture hinges Torah on rain, indicating that rain is greater than Torah.
How are we to understand this statement of Rava? Is it possible that rain is a greater benefit for the Jewish People than the Giving of the Torah?
The answer to this question is that while Torah is certainly paramount to a Jew’s existence, one cannot live in the physical world without rain and food. Indeed, the Mishna (Avos 3:17) states אִם אֵין קֶמַח ,אֵין תּוֹרָה. אִם אֵין תּוֹרָה, אֵין קֶמַח, if there is no flour there is no Torah; if there is no Torah there is no flour. The Mishna mentions flour first, as one requires sustenance before he can engage in the study of Torah. Nonetheless, one must realize that his sustenance in this world is Torah, as it is said (Mishlei 9:5) לְכוּ לַחֲמוּ בְלַחֲמִי, come and partake of my food, which is a reference to Torah study. Furthermore, it is said (Devarim 8:3) כִּי לֹא עַל הַלֶּחֶם לְבַדּוֹ יִחְיֶה הָאָדָם כִּי עַל כָּל מוֹצָא פִי יְ-ה-וָ-ה יִחְיֶה הָאָדָם, not by bread alone does man live, rather by everything that emanates from the mouth of G-d does man live, and the Arzial writes that this means that man does not live alone on the physical component in the bread. Rather, one lives through the word of HaShem, i.e. the spiritual component in the bread.
