Another interpretation: "these" are the well-founded laws. "Spread me about with apples" - these are the words of Torah, whose fragrance is good as apples. "For I am sick with love" - Rabbi Isaac said: at first, when the small coin was readily found, a person longed to hear a matter of Mishnah and a matter of Talmud; now that the small coin is not readily found, and all the more since we are sick from the kingdom, a person longs to hear a matter of Scripture and a matter of Aggadah.
Torah Sweet as Apples and the Hunger for Learning Under Rome
Yalkut Shimoni on Torah 271:4
דָּבָר אַחֵר אֵלּוּ הֲלָכוֹת הַמְּאֻשָּׁשׁוֹת. "רַפְּדוּנִי בַּתַּפּוּחִים" אֵלּוּ דִּבְרֵי תּוֹרָה שֶׁרֵיחָן טוֹב כַּתַּפּוּחִים. "כִּי חוֹלַת אַהֲבָה אָנִי" אָמַר רַבִּי יִצְחָק, בָּרִאשׁוֹנָה שֶׁהָיְתָה הַפְּרוּטָה מְצוּיָה הָיָה אָדָם מִתְאַוֶּה לִשְׁמֹעַ דְּבַר מִשְׁנָה וּדְבַר תַּלְמוּד, עַכְשָׁיו שֶׁאֵין הַפְּרוּטָה מְצוּיָה", וּבְיוֹתֵר שֶׁאָנוּ חוֹלִים מִן הַמַּלְכוּת, אָדָם מִתְאַוֶּה לִשְׁמֹעַ דְּבַר מִקְרָא דְּבַר אַגָּדָה.
