13:2י״ג:ב׳
1 א

שלח לך אנשים. לָמָּה נִסְמְכָה פָרָשַׁת מְרַגְּלִים לְפָרָשַׁת מִרְיָם? לְפִי שֶׁלָּקְתָה עַל עִסְקֵי דִבָּה, שֶׁדִּבְּרָה בְאָחִיהָ, וּרְשָׁעִים הַלָּלוּ רָאוּ וְלֹא לָקְחוּ מוּסָר (תנחומא):

שלח לך אנשים SEND THOU MEN — Why is the section dealing with the spies put in juxtaposition with the section dealing with Miriam’s punishment? To show the grievousness of the spies’ sin: because she (Miriam) was punished on account of the slander which she uttered against her brother, and these sinners witnessed it and yet they did not take a lesson from her (Midrash Tanchuma, Sh'lach 5).

שלח לך. לְדַעְתְּךָ, אֲנִי אֵינִי מְצַוֶּה לְךָ, אִם תִּרְצֶה שְׁלַח; לְפִי שֶׁבָּאוּ יִשְׂרָאֵל וְאָמְרוּ נִשְׁלְחָה אֲנָשִׁים לְפָנֵינוּ, כְּמָה שֶׁנֶּאֱמַר "וַתִּקְרְבוּן אֵלַי כֻּלְּכֶם" וְגוֹ' (דברים א'), וּמֹשֶׁה נִמְלַךְ בִּשְׁכִינָה, אָמַר, אָמַרְתִּי לָהֶם שֶׁהִיא טוֹבָה, שֶׁנֶּאֱמַר "אַעֲלֶה אֶתְכֶם מֵעֳנִי מִצְרַיִם" וְגוֹ' (שמות ג'), חַיֵּיהֶם שֶׁאֲנִי נוֹתֵן לָהֶם מָקוֹם לִטְעוֹת בְּדִבְרֵי מְרַגְּלִים, לְמַעַן לֹא יִירָשׁוּהָ (תנחומא):

שלח לך SEND THEE (more lit., for thyself) — i.e. according to your own judgement: I do not command you, but if you wish to do so send them. — God said this because the Israelites came to Moses and said. “We will send men before us etc.”, as it is said, (Deuteronomy 1:22): “And you approached me, all of you, [saying, We will send men, etc.]”, and Moses took counsel with the Shechinah (the Lord), whereupon He said to them, I have told them long ago that it (the land) is good, as it is said, (Exodus 3:17): “I will bring you up out of the affliction of Egypt … [unto a land flowing with milk and honey]”. By their lives! I swear that I will give them now an opportunity to fall into error through the statements of the spies, so that they should not come into possession of it (the land) (Sotah 34b; cf. also Rashi on Sotah 34b:8 מדעתך and Midrash Tanchuma, Sh'lach 5).
