Devarim 32:44-47 דברים ל״ב:מ״ד-מ״ז

הוא והושע בן נון. שַׁבָּת שֶׁל דְּיוֹזְגִי הָיְתָה, נִטְּלָה רְשׁוּת מִזֶּה וְנִתְּנָה לָזֶה, הֶעֱמִיד לוֹ מֹשֶׁה מְתֻרְגְּמָן לִיהוֹשֻׁעַ שֶׁיְּהֵא דוֹרֵשׁ בְּחַיָּיו, כְּדֵי שֶׁלֹּא יֹאמְרוּ יִשְׂרָאֵל בְּחַיֵּי רַבְּךָ לֹא הָיָה לְךָ לְהָרִים רֹאשׁ; וְלָמָּה קוֹרְאֵהוּ כָּאן הוֹשֵׁעַ? לוֹמַר שֶׁלֹּא זָחָה דַעְתּוֹ עָלָיו שֶׁאַעַ"פִּ שֶׁנִּתְּנָה לוֹ גְּדֻלָּה הִשְׁפִּיל עַצְמוֹ כַּאֲשֶׁר מִתְּחִלָּתוֹ (עי' ספרי):

He and Hoshe’a, the son of Nun. It was a Shabbos of shared quality, when leadership was removed from one and conferred upon the other. Moshe arranged for a public crier for Yehoshua, to enable him to expound during his lifetime, so that the Israelites would not say, ‘During your master’s lifetime you were unable to lift your head!’ And why is he entitled here “Hoshe’a”? To teach that he was not conceited, for, although leadership was conferred upon him, he was as unassuming as originally.

שימו לבבכם. צָרִיךְ אָדָם שֶׁיִּהְיוּ עֵינָיו וְלִבּוֹ וְאָזְנָיו מְכֻוָּנִים לְדִבְרֵי תוֹרָה, וְכֵן הוּא אוֹמֵר "בֶּן אָדָם רְאֵה בְעֵינֶיךָ וּבְאָזְנֶיךָ שְׁמַע וְשִׂים לִבְּךָ" (יחזקאל מ'); וַהֲרֵי דְבָרִים קַל וָחֹמֶר וּמַה תַּבְנִית הַבַּיִת שֶׁהוּא נִרְאֶה לָעֵינַיִם וְנִמְדָד בְּקָנֶה צָרִיךְ אָדָם שֶׁיִּהְיוּ עֵינָיו וְאָזְנָיו וְלִבּוֹ מְכֻוָּנִין, לְהָבִין דִּבְרֵי תוֹרָה שֶׁהֵן כַּהֲרָרִין תְּלוּיִין בִּשְׂעָרָה עַל אַחַת כַּמָּה וְכַמָּה (ספרי):

Focus your thoughts. A person is required to concentrate his sight, thought, and hearing on the word of Torah. Similarly, it says, “Son of man; view with your eyes, listen with your ears, and focus your mind.” It may be inferred from the following: Take architectural design, which is subject to visual inspection, and may be measured with the yardstick; yet a man must concentrate his sight, hearing, and thought to grasp it. Then to comprehend the word of Torah, which is comparable to a mountain balanced on a hair, most certainly so.

כי לא דבר רק הוא מכם. לֹא לְחִנָּם אַתֶּם יְגֵעִים בָּהּ, כִּי הַרְבֵּה שָׂכָר תָּלוּי בָּהּ, כי הוא חייכם; דָּ"אַ — אֵין לְךָ דָבָר רֵיקָן בַּתּוֹרָה שֶׁאִם תִּדְרְשֶׁנּוּ שֶׁאֵין בּוֹ מַתַּן שָׂכָר, תֵּדַע לְךָ שֶׁכֵּן אָמְרוּ חֲכָמִים "וַאֲחוֹת לוֹטָן תִּמְנָע" (בראשית ל"ו) "וְתִמְנַע הָיְתָה פִילֶגֶשׁ וְגוֹ'", לְפִי שֶׁאָמְרָה אֵינִי כְדַאי לִהְיוֹת לוֹ אִשָּׁה הַלְוַאי וְאֶהְיֶה פִילַגְשׁוֹ, וְכָל כָּךְ לָמָּה? לְהוֹדִיעַ שִׁבְחוֹ שֶׁל אַבְרָהָם שֶׁהָיוּ שִׁלְטוֹנִים וּמְלָכִים מִתְאַוִּים לִדַּבֵּק בְּזַרְעוֹ (ספרי):

For it is not a futile thing for you. It is not futile for you to weary yourselves with it, for enormous recompense is contingent on it — for it is your very lives. Another explanation: There is nothing in the Torah so empty that, if expounded, would not yield recompense. The proof is from the following comment by the Rabbis: “Lotan’s sister was Timna.” “Timna was the concubine, etc.” Because she said, ‘I am unworthy of being his wife — would that I may become his concubine.’ Why to that extent? This informs us of Avrohom’s eminence, as potentates and kings longed to unite themselves with his descendants.
