לדרתיכם. בִּימֵי יִרְמְיָהוּ; כְּשֶׁהָיָה יִרְמְיָהוּ מוֹכִיחָם לָמָּה אֵין אַתֶּם עוֹסְקִים בַּתּוֹרָה? וְהֵם אוֹמְרִים נַנִּיחַ מְלַאכְתֵּנוּ וְנַעֲסֹק בַּתּוֹרָה, מֵהֵיכָן נִתְפַּרְנֵס? הוֹצִיא לָהֶם צִנְצֶנֶת הַמָּן אָמַר לָהֶם אַתֶּם רְאוּ דְּבַר ה', שִׁמְעוּ לֹא נֶאֱמַר אֶלָּא רְאוּ, בָּזֶה נִתְפַּרְנְסוּ אֲבוֹתֵיכֶם, הַרְבֵּה שְׁלוּחִין יֵשׁ לוֹ לַמָּקוֹם לְהָכִין מָזוֹן לִירֵאָיו: לדרתיכם FOR YOUR GENERATIONS e. g., in the days of Jeremiah: when Jeremiah was rebuking them (the people), saying, “Why do you not engage yourselves with the Torah?”, and they answered him, “Shall we leave our work and engage ourselves with the Torah? From where shall we earn a living?”, he brought out to them the cruse of Manna and said to them, (Jeremiah 2:31) “[O Generation], see ye the thing of the Lord!” It is not said “Hear the word” but “See the thing”! — This thing is what your fathers were fed with. The Omnipresent God has many messengers (many means) to provide food for those who fear Him (Mekhilta d'Rabbi Yishmael 16:33).
