"And the LORD spoke to Moses and to Aaron, and gave them a charge concerning the children of Israel." This is what Scripture says: "Did I conceive all this people? Did I give them birth, that You should say to me, Carry them in your bosom?" (Numbers 11:12). Where had He spoken? At the time He said to him, "Go, lead the people" (Exodus 32:34). But this is still making the taught depend on what was not taught [the proof is no clearer than the thing proved]. Scripture therefore says, "And the LORD spoke to Moses and to Aaron, and gave them a charge concerning the children of Israel." He said to them: Know that My children are obstinate, they are troublesome; on this condition you must accept them upon yourselves, that they will curse you and stone you with stones.
God Warns Moses and Aaron That Israel Are a Stubborn People
Yalkut Shimoni on Torah 178:1
וַיְדַבֵּר ה' אֶל מֹשֶׁה וְאֶל אַהֲרֹן וַיְצַוֵּם אֶל בְּנֵי יִשְׂרָאֵל. זֶה שֶׁאָמַר הַכָּתוּב "הֶאָנֹכִי הָרִיתִי אֵת כָּל הָעָם הַזֶּה וְגוֹ' כִּי תֹאמַר אֵלַי שָׂאֵהוּ בְחֵיקֶךָ". הֵיכָן דִּבֵּר. בְּשָׁעָה שֶׁאָמַר לוֹ (שמות לב, לד) "לֵךְ נְחֵה אֶת הָעָם". עֲדַיִן תָּלִי תַּנְיָא בִּדְלָא תַּנְיָא. תַּלְמוּד לוֹמַר וַיְדַבֵּר ה' אֶל מֹשֶׁה וְאֶל אַהֲרֹן וַיְצַוֵּם אֶל בְּנֵי יִשְׂרָאֵל, אָמַר לָהֶם, הֱיוּ יוֹדְעִין, בָּנַי סַרְבָנִין הֵם, טַרְחָנִין הֵן, עַל מְנָת כֵּן תִּהְיוּ מְקַבְּלִין עֲלֵיכֶם, שֶׁהֵן מְקַלְּלִין אֶתְכֶם וְסוֹקְלִין אֶתְכֶם בַּאֲבָנִים.
