(Torah dropping like rain)
Devarim (Deut.) Chapter 32
יַֽעֲרֹ֤ף כַּמָּטָר֙ לִקְחִ֔י תִּזַּ֥ל כַּטַּ֖ל אִמְרָתִ֑י כִּשְׂעִירִ֣ם עֲלֵי־דֶ֔שֶׁא וְכִרְבִיבִ֖ים עֲלֵי־עֵֽשֶׂב
Devarim 32:2 My teaching shall drop like rain; my word will flow like dew; like storm winds on vegetation and like raindrops on grass
My teaching shall drop like rain: This is the testimony that you shall testify, that in your presence, I declare, "The Torah (לִקְחִי), which I gave to Israel, which provides life to the world, is just like this rain, which provides life to the world, [i.e.,] when the heavens drip down dew and rain." — [Sifrei 32:2]
like storm winds: Heb. כִּשְׂעִירִם. This is an expression similar to “storm (סְעָרָה) wind” [since ס and שׂ are interchangeable. Accordingly,] the Targum renders [כִּשְׂעִירִם as]: כְּרוּחֵי מִטְרָא, “like winds [that bring] rain.” [The metaphor is explained as follows:] Just as these [stormy, rainy] winds maintain the plants and promote their growth, so too, the words of the Torah cause those who study them to grow.
(Chabad, Rashi, Me'am Lo'ez)
