וּבְנֵ֣י צִיּ֗וֹן גִּ֤ילוּ וְשִׂמְחוּ֙ בַּיהוָ֣ה אֱלֹֽהֵיכֶ֔ם כִּֽי־נָתַ֥ן לָכֶ֛ם אֶת־הַמּוֹרֶ֖ה לִצְדָקָ֑ה וַיּ֣וֹרֶד לָכֶ֗ם גֶּ֛שֶׁם מוֹרֶ֥ה וּמַלְק֖וֹשׁ בָּרִאשֽׁוֹן׃
און איר קינדער פֿון צִיוֹן, זײַט לוסטיק און פֿרײט זיך מיט ה׳ אײַער גאָט, װאָרום ער גיט אײַך דעם פֿרירעגן ריכטיק; יאָ, ער מאַכט נידערן פֿאַר אײַך רעגן, פֿרירעגן און שפּעטרעגן אין ערשן חוֹדש .
Rashi
the teacher for justification Heb. מוֹרֶה. Your prophets who teach you to return to Me, in order to justify you.
Ibn Ezra
And the children: Yefet [ben Ali] said that the instructor (hamoreh) is the prophet that instructs them about the righteous path. And that is why good is coming to them. And it mentioned early rain (moreh) and late rain, as [in] (Judges 15:16), "With the jaw of an ass (chamor), mass (chamor) upon mass"...
Rashi
the early rain and the late rain. Heb. מוֹרֶה, like (Deut. 11:14) “the early rain (יוֹרֶה) and the late rain (וּמַלְקוֹֹש).”
Rashi
in the first month—In Nissan. Although the early rain is the first rain, which falls on the seeds, and that is in Marcheshvan, that year they sowed in Nissan, as is explained in Tractate Taanith (5a) that the grain grew in eleven days.
