30. "And Moses...sent them...all those men" (Bemidbar 13:3), MEANING THAT all were righteous and chiefs of Yisrael. However, they took bad counsel for themselves. Why did they take this counsel? It was because they thought: if Yisrael entered the land, we would be removed as chiefs and Moses would appoint other chiefs; since we deserved to be chiefs only in the desert, in the land we would not deserve TO BE CHIEFS. Due to having taken bad counsel for themselves, they died, as did all those who accepted their counsel.
30. וַיִשְׁלַח אוֹתָם מֹשֶׁה וְגוֹ,' כֻּלָּם אֲנָשִׁים. כֻּלְּהוּ זַכָּאִין הֲווֹ, וְרֵישֵׁי דְּיִשְׂרָאֵל הֲווֹ. אֲבָל אִינּוּן דִּבְּרוּ לְגַרְמַיְיהוּ עֵיטָא בִּישָׁא. אֲמַאי נַטְלֵי עֵיטָא דָּא. אֶלָּא אָמְרוּ, אִי יֵיעֲלוּן יִשְׂרָאֵל לְאַרְעָא, נִתְעֲבָר אֲנָן מִלְּמֶהֱוֵי רֵישִׁין, וְיִמְנֵי מֹשֶׁה רֵישִׁין אַחֲרָנִין, דְּהָא אֲנָן זָכֵינָן בְּמַדְבְּרָא לְמֶהֱוֵי רֵישִׁין, אֲבָל בְּאַרְעָא לָא נִזְכֵּי. וְעָל דְּנַטְלֵי עֵיטָא בִּישָׁא לְגַרְמַיְיהוּ, מִיתוּ אִינּוּן, וְכָל אִינּוּן דְּנַטְלָן מִלַּיְיהוּ.
