Rabbi Yishmael and Rabbi Shimon bar Yochai debate whether one should combine Torah study with worldly labor; Rabbi Shimon holds Torah must be total and uninterrupted, while Rabbi Yishmael permits work alongside Torah. The Talmud records that many followed Rabbi Yishmael's view.
תָּנוּ רַבָּנַן: ״וְאָסַפְתָּ דְגָנֶךָ״ מָה תַּלְמוּד לוֹמַר? — לְפִי שֶׁנֶּאֱמַר: ״לֹא יָמוּשׁ סֵפֶר הַתּוֹרָה הַזֶּה מִפִּיךָ״ — יָכוֹל דְּבָרִים כִּכְתָבָן, תַּלְמוּד לוֹמַר: ״וְאָסַפְתָּ דְגָנֶךָ״ — הַנְהֵג בָּהֶן מִנְהַג דֶּרֶךְ אֶרֶץ, דִּבְרֵי רַבִּי יִשְׁמָעֵאל. רַבִּי שִׁמְעוֹן בֶּן יוֹחַאי אוֹמֵר: אֶפְשָׁר אָדָם חוֹרֵשׁ בִּשְׁעַת חֲרִישָׁה, וְזוֹרֵעַ בִּשְׁעַת זְרִיעָה, וְקוֹצֵר בִּשְׁעַת קְצִירָה, וְדָשׁ בִּשְׁעַת דִּישָׁה, וְזוֹרֶה בִּשְׁעַת הָרוּחַ, תּוֹרָה מַה תְּהֵא עָלֶיהָ? אֶלָּא בִּזְמַן שֶׁיִּשְׂרָאֵל עוֹשִׂין רְצוֹנוֹ שֶׁל מָקוֹם — מְלַאכְתָּן נַעֲשֵׂית עַל יְדֵי אֲחֵרִים, שֶׁנֶּאֱמַר: ״וְעָמְדוּ זָרִים וְרָעוּ צֹאנְכֶם וְגוֹ׳״, וּבִזְמַן שֶׁאֵין יִשְׂרָאֵל עוֹשִׂין רְצוֹנוֹ שֶׁל מָקוֹם — מְלַאכְתָּן נַעֲשֵׂית עַל יְדֵי עַצְמָן, שֶׁנֶּאֱמַר: ״וְאָסַפְתָּ דְגָנֶךָ״. וְלֹא עוֹד אֶלָּא שֶׁמְּלֶאכֶת אֲחֵרִים נַעֲשֵׂית עַל יָדָן, שֶׁנֶּאֱמַר: ״וְעָבַדְתָּ אֶת אוֹיְבֶךָ וְגוֹ׳״. אָמַר אַבָּיֵי: הַרְבֵּה עָשׂוּ כְּרַבִּי יִשְׁמָעֵאל, וְעָלְתָה בְּיָדָן. כְּרַבִּי שִׁמְעוֹן בֶּן יוֹחַי, וְלֹא עָלְתָה בְּיָדָן.
The Sages taught: What is the meaning of that which the verse states: “And you shall gather your grain”? Because it is stated: “This Torah shall not depart from your mouths, and you shall contemplate in it day and night” (Joshua 1:8), I might have thought that these matters are to be understood as they are written; one is to literally spend his days immersed exclusively in Torah study. Therefore, the verse states: “And you shall gather your grain, your wine and your oil,” assume in their regard, the way of the world; set aside time not only for Torah, but also for work. This is the statement of Rabbi Yishmael. Rabbi Shimon ben Yoḥai says: Is it possible that a person plows in the plowing season and sows in the sowing season and harvests in the harvest season and threshes in the threshing season and winnows in the windy season, as grain is separated from the chaff by means of the wind, and is constantly busy; what will become of Torah? Rather, one must dedicate himself exclusively to Torah at the expense of other endeavors; as when Israel performs God’s will, their work is performed by others, as it is stated: “And strangers will stand and feed your flocks, and foreigners will be your plowmen and your vinedressers” (Isaiah 61:5). When Israel does not perform God’s will, their work is performed by them themselves, as it is stated: “And you shall gather your grain.” Moreover, if Israel fails to perform God’s will, others’ work will be performed by them, as it is stated: “You shall serve your enemy whom God shall send against you, in hunger, in thirst, in nakedness and in want of all things” (Deuteronomy 28:48). Summing up this dispute, Abaye said: Although there is room for both opinions, many have acted in accordance with the opinion of Rabbi Yishmael, and combined working for a living and learning Torah, and although they engaged in activities other than the study of Torah, were successful in their Torah study. Many have acted in accordance with the opinion of Rabbi Shimon ben Yoḥai and were not successful in their Torah study. They were ultimately forced to abandon their Torah study altogether.
