ציטירנדיקער פּירוש אויף דניאל 11:40

יערוף כמטר לקחי, “may my instruction drip like rain;” the word יערוף is close in meaning to words such as הזלה and ירידה, the former being used in connection with the descent of dew, i.e. יערף כטל in 33,28. Moses prays that his words should be heard and firmly embedded in the hearts of his listeners, much as rain is embedded in the earth. The meaning of the word לקחי, “my teaching,” may be an allusion to what Moses himself had “taken,” לקח, from heaven when he received the Torah; this should now perform the same kind of work on his listeners as rain does on the earth upon which it falls. Just as such rain is useful in initiating growth of vegetation, his words should initiate fruitful under-standing of the Torah by the people who hear him.
The words כשעירים עלי דשא, commonly translated as “like storm winds upon vegetation,” reflect the word רוח, in the sense of רוח סערה, a stormy wind. The word סערה has been changed slightly in that the letter ס has been replaced by the letter ש, not an unusual occurrence. Another example is Daniel 11,40 וישתער עליו, This is also the opinion of Onkelos who translates ברוחי מטרא דנשבין על דתאה, “like blowing rain-winds on the grass.” The rains strengthen the grass.

the word downpours [Hebrew: revivim] (both words are adjectives) comes from the Hebrew word for “abundant” [Hebrew: rav], since the word vegetation generally denotes a stronger kind of plant than the word grass. Some say that the word showers comes from the word “hair”. Others have related it to “the storm wind of God ” [Jeremiah 23: 19], albeit the former is spelled with a s̀in whereas the latter is spelled with a samekh (similarly, “shall come against him like a storm” [Daniel 11: 40], is spelled with a s̀in, although its meaning is identical to the same word spelled with a samakh). It is also possible that the word simply has no cognate in Scripture. Employing the customary prophetic style, Scripture expresses the same idea twice, for emphasis, the idea being that Moshe prays for his words to fall like dew and rain. Dew and rain do not descend without effect; they never fall without, as it is written, “watering the earth” [Isaiah 55: 10]. The idea is that Moshe’s words should enter the hearts of his audience in the same way that rain and dew enter the earth, causing it to bear life, and to flourish.

trembled before them From “shall come against him like a storm” [Daniel 11: 40], and also “it made the hair of my flesh bristle up” [Job 4: 15] — meaning, they did not fear them (although there is a pronomial suffix, the preposition before is implied; cf. “my children have gone out from me” [Jeremiah 10: 20], and “you are stronger than I, and have prevailed” [Jeremiah 20: 7]). The word is related to “tempest” [Hebrew: searah] [Ezekiel 1: 4] even though the latter word is spelled with a samekh.
