Work...WORK?! (apologies to Maynard G Krebs) The spiritual imperative for earning a livelihood
The Argument:
We are given Torah as instruction for action in the world. We are in the world to till it and tend it and to provide for our families in partnership with HaShem - this is דרך ארץ - the way of the world.
"The Torah is meant to be lived, not studied. We are to meditate on it day and night, night and day, not by withdrawing from the world into the beit midrash, “the house of study,” but rather by engaging fully in the world while meditating on the Torah and its teaching regarding honesty and living with awareness."
from A Book of Life (Schocken Books) by Rabbi Michael Strassfeld
דרך ארץ, literally "the way of the world," depending on context, is commonly translated as:
  1. Proper behavior - Menschlikeit (or, as in a translation below "the desired mode of behavior")
  2. "Worldly occupation" profession, livelihood
  3. Sexual relations
Keep all these meanings in mind as aspects of one thing as we explore the spiritual imperative of engaging in דרך ארץ

(ח) וַיַּעֲנ֨וּ כָל־הָעָ֤ם יַחְדָּו֙ וַיֹּ֣אמְר֔וּ כֹּ֛ל אֲשֶׁר־דִּבֶּ֥ר ה' נַעֲשֶׂ֑ה ...

(8) All the people answered as one, saying, “All that <HaShem> has spoken we will do!” ...

(ז) וַיִּקַּח֙ סֵ֣פֶר הַבְּרִ֔ית וַיִּקְרָ֖א בְּאָזְנֵ֣י הָעָ֑ם וַיֹּ֣אמְר֔וּ כֹּ֛ל אֲשֶׁר־דִּבֶּ֥ר ה' נַעֲשֶׂ֥ה וְנִשְׁמָֽע׃

(7) Then he took the record of the covenant and read it aloud to the people. And they said, “All that <HaShem> has spoken we will do and we will listen!”

(כח) וַיְבָ֣רֶךְ אֹתָם֮ אֱלֹקִים֒ וַיֹּ֨אמֶר לָהֶ֜ם אֱלֹקִ֗ים פְּר֥וּ וּרְב֛וּ וּמִלְא֥וּ אֶת־הָאָ֖רֶץ וְכִבְשֻׁ֑הָ וּרְד֞וּ בִּדְגַ֤ת הַיָּם֙ וּבְע֣וֹף הַשָּׁמַ֔יִם וּבְכָל־חַיָּ֖ה הָֽרֹמֶ֥שֶׂת עַל־הָאָֽרֶץ׃

(28) God blessed them and God said to them, “Be fertile and increase, fill the earth and master it; and rule the fish of the sea, the birds of the sky, and all the living things that creep on earth.”

(ה) וְכֹ֣ל ׀ שִׂ֣יחַ הַשָּׂדֶ֗ה טֶ֚רֶם יִֽהְיֶ֣ה בָאָ֔רֶץ וְכָל־עֵ֥שֶׂב הַשָּׂדֶ֖ה טֶ֣רֶם יִצְמָ֑ח כִּי֩ לֹ֨א הִמְטִ֜יר ה' אֱלֹקִים֙ עַל־הָאָ֔רֶץ וְאָדָ֣ם אַ֔יִן לַֽעֲבֹ֖ד אֶת־הָֽאֲדָמָֽה׃

(5) No shrub of the field was yet in the earth, and no herb of the field had yet sprung up; for <HaShem> God had not caused it to rain upon the earth, and there was not a man to till the ground;

(טו) וַיִּקַּ֛ח ה' אֱלֹקִ֖ים אֶת־הָֽאָדָ֑ם וַיַּנִּחֵ֣הוּ בְגַן־עֵ֔דֶן לְעָבְדָ֖הּ וּלְשָׁמְרָֽהּ׃

(15) <HaShem> God took the man and placed him in the garden of Eden, to till it and tend it.

(יז) וּלְאָדָ֣ם אָמַ֗ר כִּֽי־שָׁמַעְתָּ֮ לְק֣וֹל אִשְׁתֶּךָ֒ וַתֹּ֙אכַל֙ מִן־הָעֵ֔ץ אֲשֶׁ֤ר צִוִּיתִ֙יךָ֙ לֵאמֹ֔ר לֹ֥א תֹאכַ֖ל מִמֶּ֑נּוּ אֲרוּרָ֤ה הָֽאֲדָמָה֙ בַּֽעֲבוּרֶ֔ךָ בְּעִצָּבוֹן֙ תֹּֽאכֲלֶ֔נָּה כֹּ֖ל יְמֵ֥י חַיֶּֽיךָ׃ (יח) וְק֥וֹץ וְדַרְדַּ֖ר תַּצְמִ֣יחַֽ לָ֑ךְ וְאָכַלְתָּ֖ אֶת־עֵ֥שֶׂב הַשָּׂדֶֽה׃ (יט) בְּזֵעַ֤ת אַפֶּ֙יךָ֙ תֹּ֣אכַל לֶ֔חֶם עַ֤ד שֽׁוּבְךָ֙ אֶל־הָ֣אֲדָמָ֔ה כִּ֥י מִמֶּ֖נָּה לֻקָּ֑חְתָּ כִּֽי־עָפָ֣ר אַ֔תָּה וְאֶל־עָפָ֖ר תָּשֽׁוּב׃

(17) To Adam He said, “Because you did as your wife said and ate of the tree about which I commanded you, ‘You shall not eat of it,’ Cursed be the ground because of you; By toil shall you eat of it All the days of your life: (18) Thorns and thistles shall it sprout for you. But your food shall be the grasses of the field; (19) By the sweat of your brow Shall you get bread to eat, Until you return to the ground— For from it you were taken. For dust you are, And to dust you shall return.”

(יד) וְנָתַתִּ֧י מְטַֽר־אַרְצְכֶ֛ם בְּעִתּ֖וֹ יוֹרֶ֣ה וּמַלְק֑וֹשׁ וְאָסַפְתָּ֣ דְגָנֶ֔ךָ וְתִֽירֹשְׁךָ֖ וְיִצְהָרֶֽךָ׃

(14) I will grant the rain for your land in season, the early rain and the late. You shall gather in your new grain and wine and oil—

(ב) יְגִ֣יעַ כַּ֭פֶּיךָ כִּ֣י תֹאכֵ֑ל אַ֝שְׁרֶ֗יךָ וְט֣וֹב לָֽךְ׃

(2) By the labor of your hands you shall eat; you shall be happy and it will be good for you

(טו) בגן...רק פירוש לעבדה על הגן שמפריו יאכל ואחר שחטא שב לאכול את עשב השדה והוא הלחם

In the garden...The only interpretation of working in the garden he will have fruit to eat [is] after he has sinned, he returns to eat the grass of the field, which is the bread

Radak on Shemot 2:15:2
(15) לעבדה ולשמרה, to work it and to preserve it intact. ...The word לעבדה refers to constructive labour, furthering the growth and fruit-bearing capability of the trees, whereas the word ולשמרה refers to the taking of preventive measures to counter invasion of the garden by predators, and other measures to prevent its deterioration. Our sages, reading into this expression also a moral/ethical teaching, understand the word לעבדה as the dedication to study of G’d’s commandments, whereas the expression לשמרה refers to the carrying out of these commandments in practice. (Sifri Eykev 21)

(ב) רַבָּן גַּמְלִיאֵל בְּנוֹ שֶׁל רַבִּי יְהוּדָה הַנָּשִׂיא אוֹמֵר, יָפֶה תַלְמוּד תּוֹרָה עִם דֶּרֶךְ אֶרֶץ, שֶׁיְּגִיעַת שְׁנֵיהֶם מְשַׁכַּחַת עָוֹן. וְכָל תּוֹרָה שֶׁאֵין עִמָּהּ מְלָאכָה, סוֹפָהּ בְּטֵלָה וְגוֹרֶרֶת עָוֹן. וְכָל הָעֲמֵלִים עִם הַצִּבּוּר, יִהְיוּ עֲמֵלִים עִמָּהֶם לְשֵׁם שָׁמַיִם, שֶׁזְּכוּת אֲבוֹתָם מְסַיַּעְתָּן וְצִדְקָתָם עוֹמֶדֶת לָעַד. וְאַתֶּם, מַעֲלֶה אֲנִי עֲלֵיכֶם שָׂכָר הַרְבֵּה כְּאִלּוּ עֲשִׂיתֶם:

(2) Rabban Gamliel the son of Rabbi Yehudah HaNasi said: Excellent is the study of the Torah together with a worldly occupation; for the exertion [expended] in both of them causes sin to be forgotten. And all [study of the] Torah in the absence of a worldly occupation comes to nothing in the end and leads to sin. And all who work for the community, let them work for the [sake of the] name of Heaven; for the merit of their ancestors sustains them, And their righteousness (tsidkatam) will endure forever. And as for you [who work for the community, God says:] I credit you with a great reward, as if you [yourselves] had done it [on your own].

(ב) דרך ארץ. מלאכה או סחורה:

(ג) שיגיעת שניהם משכחת עון. שהתורה מתשת כחו של אדם, והמלאכה מפרכת ומשברת את הגוף, ומתוך כך יצר הרע בטל ממנו:

(ד) וכל תורה שאין עמה מלאכה. ואם תאמר יהא עמל בתורה תמיד ויגיעתה תהא משכחת עון, ומה צורך למלאכה, לכך הוזקק לומר וכל תורה שאין עמה מלאכה סופה בטלה, לפי שאי אפשר לו בלא מזונות, ומלסטם את הבריות ומשכח תלמודו:

(2) "Worldly occupation (derekh erets, literally the way of the world)": A craft or business. *

(3) "For the exertion [expended] in both of them causes sin to be forgotten": As Torah [study] dulls the strength of a man and work pulls apart and breaks the body, and as a result of this the evil impulse is rendered idle for him.

(4) "And all [study of the] Torah in the absence of a worldly occupation": And if one might ask, let him work in Torah [study] and its exertion will cause sin to be forgotten, therefore it is required to say, "all [study of the] Torah in the absence of a worldly occupation comes to nothing in the end." As it is impossible for him without food, and [so] he will rob the creatures and forget his study.

(5) "let them work for the [sake of the] name of Heaven": and not in order to take a crown [for themselves], to say, "I did such and such for the community."

(ד) וכל התורה שאין עמה מלאכה סופה בטלה. כענין שאמרו במכילתין (ג יז) אם אין קמח אין תורה. הענין כמשמעו כשיתבטל ממלאכה מביאתו אל העוני וגוררת כמה עונות ורעתה רבה כי מפניה יאהב מתנות ולא יחיה. ויחניף בני אדם אף אם הם רשעים כדי שיתנו לו. גם כי יתם הכסף מהמתנות יהיה גנב או קוביוסטוס ויביא גזלות העני לביתו לבל ימות ברעב. ובהגיע אדם אל המדות האלה אין מעצר לרוחו ולא ינוח ולא ישקוט עד יעבור על כל המצות האמורות בתורה כי עבירה גוררת עבירה. ועל זה ארז"ל במסכת חולין (ברכות ח.) כל הנהנה מיגיעו עליו הכתוב אומר (תהלים קכ"ח ב') יגיע כפיך כי תאכל אשריך וטוב לך. אשריך בעולם הזה וטוב לך לעולם (הבא) . על כן צריך לחכם שידע מלאכה כענין שנא' (קהלת ז' י"א) טובה חכמה עם נחלה:

(4) And all [study of the] Torah in the absence of a worldly occupation comes to nothing in the end: Like the matter that they said in our treatise (Avot 3 17), "If there is no flour, there is no Torah." The matter is like its simple understanding - when he neglects work, it brings him to poverty and it drags along several sins and its evil is great. As on account of it, he will 'love gifts and not live,' and flatter people even if they are evildoers, in order that they give to him. Also when the money from the gifts runs out, he will become a thief or a kidnapper (or gambler) and will bring 'home loot taken from the poor' so that he not die of hunger. And when a person reaches these traits, his spirit knows no restraint and he will not rest and not be still until he transgresses all of the commandments that are stated in the Torah, since 'one sin brings along [another] sin.' And about this, the sages said in Tractate Chullin 44b (see also Berakhot 8a), "Anyone who benefits from his toil, the verse states about him (Psalms 128:2), 'If you eat the toil of your hands you shall be happy and it will be good for you' - happy in this world, and good for you in the world (to come)." Therefore it is necessary for a sage to know a craft, as it is stated (Ecclesiastes 7:11), "Good is wisdom with an inheritance."

(יז) רַבִּי אֶלְעָזָר בֶּן עֲזַרְיָה אוֹמֵר, אִם אֵין תּוֹרָה, אֵין דֶּרֶךְ אֶרֶץ. אִם אֵין דֶּרֶךְ אֶרֶץ, אֵין תּוֹרָה. אִם אֵין חָכְמָה, אֵין יִרְאָה. אִם אֵין יִרְאָה, אֵין חָכְמָה. אִם אֵין בִּינָה, אֵין דַּעַת. אִם אֵין דַּעַת, אֵין בִּינָה. אִם אֵין קֶמַח, אֵין תּוֹרָה. אִם אֵין תּוֹרָה, אֵין קֶמַח. הוּא הָיָה אוֹמֵר, כָּל שֶׁחָכְמָתוֹ מְרֻבָּה מִמַּעֲשָׂיו, לְמַה הוּא דוֹמֶה, לְאִילָן שֶׁעֲנָפָיו מְרֻבִּין וְשָׁרָשָׁיו מֻעָטִין, וְהָרוּחַ בָּאָה וְעוֹקַרְתּוֹ וְהוֹפַכְתּוֹ עַל פָּנָיו, שֶׁנֶּאֱמַר (ירמיה יז) וְהָיָה כְּעַרְעָר בָּעֲרָבָה וְלֹא יִרְאֶה כִּי יָבוֹא טוֹב וְשָׁכַן חֲרֵרִים בַּמִּדְבָּר אֶרֶץ מְלֵחָה וְלֹא תֵשֵׁב. אֲבָל כָּל שֶׁמַּעֲשָׂיו מְרֻבִּין מֵחָכְמָתוֹ, לְמַה הוּא דוֹמֶה, לְאִילָן שֶׁעֲנָפָיו מֻעָטִין וְשָׁרָשָׁיו מְרֻבִּין, שֶׁאֲפִלּוּ כָל הָרוּחוֹת שֶׁבָּעוֹלָם בָּאוֹת וְנוֹשְׁבוֹת בּוֹ אֵין מְזִיזִין אוֹתוֹ מִמְּקוֹמוֹ, שֶׁנֶּאֱמַר (שם) וְהָיָה כְּעֵץ שָׁתוּל עַל מַיִם וְעַל יוּבַל יְשַׁלַּח שָׁרָשָׁיו וְלֹא יִרְאֶה כִּי יָבֹא חֹם, וְהָיָה עָלֵהוּ רַעֲנָן, וּבִשְׁנַת בַּצֹּרֶת לֹא יִדְאָג, וְלֹא יָמִישׁ מֵעֲשׂוֹת פֶּרִי:

(17) Rabbi Elazar ben Azariah says: If there is no Torah, there is no worldly occupation; if there is no worldly occupation, there is no Torah. If there is no wisdom, there is no fear; if there is no fear, there is no wisdom. If there is no understanding, there is no knowledge; if there is no knowledge, there is no understanding. If there is no flour, there is no Torah; if there is no Torah, there is no flour. He would say: Anyone whose wisdom exceeds his deeds, to what is he compared? To a tree whose branches are many but whose roots are few; and the wind comes and uproots it and turns it upside down; as it is said; "And he shall be like a lonely juniper tree in the wasteland and shall not see when good comes, but shall inhabit the parched places of the wilderness, a salty land that is uninhabitable." (Jeremiah 17:6). But one whose deeds exceed his wisdom, what is he like? Like a tree whose branches are few but whose roots are many; since even if all the winds of the world come and blow upon it, they do not move it from its place, as it is said; "He shall be like a tree planted by the waters, and spreads out its roots by the river, and shall not perceive when heat comes, but its leaf shall remain fresh; and it will not be troubled in the year of drought, nor will it cease to bear fruit." (Jeremiah 17:8).

(יז) אם אין תורה וכו׳ אין משאו ומתנו יפה עם הבריות:

(יח) אם אין דרך ארץ וכו׳ סוף שתורתו משתכחת ממנו:

(יט) אם אין דעת וכו׳ דעת, הוא שמוצא טעם לדבר. ובינה, הוא שמבין דבר מתוך דבר אבל אינו מראה לו טעם. ואם אין דעת לתת טעם לדבר אין בינה, אחר שלא ידע טעמו של דבר כאילו לא ידעו. ומכל מקום הבינה היא קודמת, לפיכך אם אין בינה אין דעת:

(כ) אם אין קמח אין תורה. מי שאין לו מה יאכל היאך יעסוק בתורה:

(כא) אם אין תורה אין קמח. מה יועיל לו הקמח שבידו, הואיל ואין בו תורה, נוח לו שלא היה לו קמח והיה מת ברעב:

(17) "If there is no Torah, etc.": [then] his give and take is not well with the creatures.

(18) "if there is no worldly occupation, etc.": in the end, his Torah will be forgotten from him.

(19) "if there is no knowledge, etc.": Knowledge is the finding of the reason for a thing and understanding is to figure out one thing from [another] thing, but without seeing its reason. And if there is no knowledge to give the reason for a thing, there is no understanding, since if he does not know the reason of a thing, it is as if he doesn't know it. But nevertheless, understanding is first, hence "if there is no understanding, there is no knowledge."

(20) "If there is no flour, there is no Torah": How will one who does not have what to eat, inolve himself in Torah [study]?

(21) "if there is no Torah, there is no flour": Of what good to him is the flour that is in his hand; since he does not have Torah, it would have been better for him that he did not have flour and that would have died from starvation.

ואמר רבי חייא בר אמי משמיה דעולא גדול הנהנה מיגיעו יותר מירא שמים דאילו גבי ירא שמים כתיב (תהלים קיב, א) אשרי איש ירא את ה' ואילו גבי נהנה מיגיעו כתיב (תהלים קכח, ב) יגיע כפיך כי תאכל אשריך וטוב לך אשריך בעולם הזה וטוב לך לעולם הבא ולגבי ירא שמים וטוב לך לא כתיב ביה:

And Rabbi Ḥiyya bar Ami said in the name of Ulla: One who benefits from his hard labor is greater than a God-fearing person, i.e., one who is so enthralled by his fear of God that he sits idly by and does not work. As with regard to a God-fearing person, it is written: “Happy is the man who fears the Lord, who greatly desires His mitzvot” (Psalms 112:1), while with regard to one who benefits from his hard work, it is written: “By the labor of your hands you will live; you are happy and it is good for you” (Psalms 128:2). The Gemara explains this verse to mean that you are happy in this world, and it is good for you in the World-to-Come. And regarding a God-fearing person, happy is the man, is written about him but and it is good for you, is not written about him.

...ת"ר ואספת דגנך מה ת"ל לפי שנא' (יהושע א, ח) לא ימוש ספר התורה הזה מפיך יכול דברים ככתבן ת"ל ואספת דגנך הנהג בהן מנהג דרך ארץ דברי ר' ישמעאל ר"ש בן יוחי אומר אפשר אדם חורש בשעת חרישה וזורע בשעת זריעה וקוצר בשעת קצירה ודש בשעת דישה וזורה בשעת הרוח תורה מה תהא עליה אלא בזמן שישראל עושין רצונו של מקום מלאכתן נעשית ע"י אחרים שנא' (ישעיהו סא, ה) ועמדו זרים ורעו צאנכם וגו' ובזמן שאין ישראל עושין רצונו של מקום מלאכתן נעשית ע"י עצמן שנא' (דברים יא, יד) ואספת דגנך ולא עוד אלא שמלאכת אחרים נעשית על ידן שנא' (דברים כח, מח) ועבדת את אויביך וגו' אמר אביי הרבה עשו כרבי ישמעאל ועלתה בידן כר' שמעון בן יוחי ולא עלתה בידן א"ל רבא לרבנן במטותא מינייכו ביומי ניסן וביומי תשרי לא תתחזו קמאי כי היכי דלא תטרדו במזונייכו כולא שתא:

...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. Similarly, Rava said to the Sages who would attend his study hall: I implore you; during the months of Nisan and Tishrei, the crucial agricultural periods, do not appear before me. Engage in your agricultural work then so that you will not be preoccupied with your sustenance all year.

מתני׳ כל שישנו במקרא ובמשנה ובדרך ארץ לא במהרה הוא חוטא שנאמר (קהלת ד, יב) והחוט המשולש לא במהרה ינתק וכל שאינו לא במקרא ולא במשנה ולא בדרך ארץ אינו מן היישוב

MISHNA: Anyone who is engaged in the study of Bible, and in the study of Mishna, and in דרך ארץ, will not be quick to sin, as it is stated: “And a threefold cord is not quickly broken” (Ecclesiastes 4:12). One who is involved in all three of these activities will not sin easily. And anyone who does not engage in the study of Bible, nor the study of Mishna, nor in דרך ארץ - the desired mode of behavior, is not part of society, i.e., he is not considered a civilized person at all.

אמר להן כך מקובלני מבית אבי אבא לעולם ישכיר אדם עצמו לע"ז ואל יצטרך לבריות

...

...והוא סבר לע"ז ממש ולא היא אלא ע"ז עבודה שזרה לו כדאמר ליה רב לרב כהנא נטוש נבילתא בשוקא ושקול אגרא ולא תימא גברא רבא אנא וזילא בי מילתא

Jonathan said to them: This is the tradition that I received from the house of my father’s father: A person should always hire himself out to idol worship and not require the help of people by receiving charity, and I took this position in order to avoid having to take charity.

...

The Gemara comments: And he, Jonathan, thought that this referred to actual idol worship, but that is not so, that was not the intent of the tradition. Rather, here the term idol worship, literally: Strange service, is referring to service, i.e., labor, that is strange, i.e., unsuitable, for him. In other words, one should be willing to perform labor that is difficult and humiliating in his eyes rather than become a recipient of charity. As Rav said to Rav Kahana, his student: Skin a carcass in the market and take payment, but do not say: I am a great man and this matter is beneath me.

(יח) לְעוֹלָם יִדְחֹק אָדָם עַצְמוֹ וְיִתְגַּלְגֵּל בְּצַעַר וְאַל יִצְטָרֵךְ לַבְּרִיּוֹת וְאַל יַשְׁלִיךְ עַצְמוֹ עַל הַצִּבּוּר. וְכֵן צִוּוּ חֲכָמִים וְאָמְרוּ עֲשֵׂה שַׁבַּתְּךָ חֹל וְאַל תִּצְטָרֵךְ לַבְּרִיּוֹת. וַאֲפִלּוּ הָיָה חָכָם וּמְכֻבָּד וְהֶעֱנִי יַעֲסֹק בְּאֻמְּנוּת וַאֲפִלּוּ בְּאֻמְּנוּת מְנֻוֶּלֶת וְלֹא יִצְטָרֵךְ לַבְּרִיּוֹת. מוּטָב לִפְשֹׁט עוֹר בְּהֵמוֹת נְבֵלוֹת וְלֹא יֹאמַר לָעָם חָכָם גָּדוֹל אֲנִי כֹּהֵן אֲנִי פַּרְנְסוּנִי. וּבְכָךְ צִוּוּ חֲכָמִים. גְּדוֹלֵי הַחֲכָמִים הָיוּ מֵהֶם חוֹטְבֵי עֵצִים וְנוֹשְׂאֵי הַקּוֹרוֹת וְשׁוֹאֲבֵי מַיִם לַגִּנּוֹת וְעוֹשֵׂי הַבַּרְזֶל וְהַפֶּחָמִים וְלֹא שָׁאֲלוּ מִן הַצִּבּוּר וְלֹא קִבְּלוּ מֵהֶם כְּשֶׁנָּתְנוּ לָהֶם:

(18) A person should always push himself and live in misery and not require help from others and not thrust himself upon the community. And so [too], did the Sages command and say (Pesachim 112a), "make your Shabbat to be like a weekday and do not require help from others." And even if he was a sage and an honored man and became poor, he should engage in crafts - and even in abject crafts - and not require help from others. It is better to flay the skins of animal carcasses than that he should say to the people, "I am a great sage, I am a priest (Kohen), support me;" and this is what the Sages commanded. There were from the greatest of the Sages wood-choppers (1), beam carriers (2), water bearers [who would bring it] to the gardens (3) and iron and coal makers (4); and they would not ask [for help] from the community and would not take it from them when they [offered to] give it to them.

(ט) גְּדוֹלֵי חַכְמֵי יִשְׂרָאֵל הָיוּ מֵהֶן חוֹטְבֵי עֵצִים וּמֵהֶן שׁוֹאֲבֵי מַיִם וּמֵהֶן סוּמִים וְאַף עַל פִּי כֵן הָיוּ עוֹסְקִין בְּתַלְמוּד תּוֹרָה בַּיּוֹם וּבַלַּיְלָה וְהֵם מִכְּלַל מַעְתִּיקֵי הַשְּׁמוּעָה אִישׁ מִפִּי אִישׁ מִפִּי משֶׁה רַבֵּנוּ:

(9) Among the great ones of the sages of Israel, there were wood-choppers (1) and water-drawers (3), and blind men, and despite this, they engaged in Torah study during the day and night, and are included among the transmitters of the tradition from person to person from Moses, our teacher.

1. In his Commentary to the Mishnah , the Rambam mentions that Hillel earned his livelihood in this manner. It must be noted that although Yoma 35b describes Hillel as having earned a meager livelihood through physical work, neither it, nor any other known source, explicitly states that Hillel would chop wood.
2. Gittin 67b states that Rav Sheshet would haul beams. See the Rambam's Commentary to the Mishnah (loc. cit.), where he elaborates on the labor performed by the sages. He apparently had a slightly different version of the Talmud, for he refers to different sages than those mentioned in the standard published text.
3. Ketubot 105a mentions that Rav Huna was a water-carrier.
4. Berachot 28b states that Rabbi Yehoshua would work in this capacity.

...Love Work: What is that? This teaches that a man should love work and that no man should hate work. For even as the Torah was given as a covenant, so was work given as a covenant; as it is said "Six days &tc" (Shemot 20:9)

...

Rabbi Simeon ben Eleazar says: Even Adam tasted nothing before he worked, as it is said: "And he put him in the Garden to till it and tend it; [only then] Of every tree of the garden you may eat." (B'reishit 2:15)

Rabbi Tarfon says: Ha KBH, likewise did not cause His Shekhinah to rest upon Israel before they did work as it is said "And let them make Me a sanctuary, then I shall dwell among them" (Shemot 25:8)

Rabbi Judah ben Bathyra says: If a man has no work to do, what should he do? If he has a run-down yard or field, let him go and occupy himself with it, for it is said "Six days &tc" Now why does the verse day "And do all they work?" To include him who has rundown yards and fields, let him go occupy himself with them.

ללמדו אומנות מנלן אמר חזקיה דאמר קרא (קהלת ט, ט) ראה חיים עם אשה אשר אהבת אם אשה ממש היא כשם שחייב להשיאו אשה כך חייב ללמדו אומנות אם תורה היא כשם שחייב ללמדו תורה כך חייב ללמדו אומנות
§ The baraita further states that a father is commanded to teach his son a trade. The Gemara asks: From where do we derive this? Ḥizkiyya said: As the verse states: “Enjoy life with the wife whom you love” (Ecclesiastes 9:9). If this verse is interpreted literally, and it is referring to an actual woman, then one can derive as follows: Just as a father is obligated to marry his son to a woman, so too, he is obligated to teach him a trade, as indicated by the term: Life. And if the wife mentioned in this verse is allegorical, and it is the Torah, then one should explain the verse in the following manner: Just as he is obligated to teach him Torah, so too, he is obligated to teach him a trade.

רבי יהודה אומר כל שאינו מלמדו אומנות מלמדו ליסטות ליסטות ס"ד אלא כאילו מלמדו ליסטות

...

מאי בינייהו איכא בינייהו דאגמריה עיסקא

§ The baraita further teaches that Rabbi Yehuda says: Any father who does not teach his son a trade teaches him banditry. The Gemara asks: Can it enter your mind that he actually teaches him banditry? Rather, the baraita means that it is as though he taught him banditry.

...

The Gemara asks: What is the difference between the opinion of the first tanna and that of Rabbi Yehuda? Both state that a father must teach his son a trade. The Gemara answers: There is a difference between them in a case where the father teaches him to engage in business. According to the first tanna this is sufficient, whereas Rabbi Yehuda maintains that he must teach him an actual trade.

עיסקא - אם למדו סחורה לת"ק הרי למדו חיים לרבי יהודה דאתי לטעמא אומנות דוקא דכמה פעמים שאין לו במה לעשות סחורה ועומד ומלסטם:

According to the Tana Kamma, the father has fulfilled his obligation by giving his son a means of support. But according to R' Yehudah, the father hasn't yet fulfilled his obligation since business isn't a secure livelihood, since there are times where no merchandise is available to sell and the son would, during these times, resort to stealing.

... המנונא כל המתפלל בע"ש ואומר ויכולו מעלה עליו הכתוב כאילו נעשה שותף להקב"ה במעשה בראשית שנאמר ויכולו אל תקרי ויכולו אלא ויכלו

...Rav Hamnuna said: Anyone who prays on Shabbat evening and recites the passage of vaykhullu, the verse ascribed him credit as if he became a partner with the Holy One, Blessed be He, in the act of Creation. As it is stated: “And the heavens and the earth were finished [vaykhullu].” Do not read it as: Were finished [vaykhullu]; rather, as: They finished [vaykhallu]. It is considered as though the Holy One, Blessed be He, and the individual who says this become partners and completed the work together.

When the Torah tells us the story of creation, its intention is not to reveal metaphysical secrets but to teach us a practical law. The description of creation is a legal text, in which are to be found everlasting halachic principles, just like in Parashat Kedoshim or Parashat Mishpatim. If the Torah chose to relate the tale of creation to man, we may clearly derive one law from this manner of procedure - viz., that man is obliged to engage in creation and the renewal of the cosmos.
...
God gave the Book of Creation to man not simply for the sake of theoretical study, but in order than man might continue the act of creation.
HaRav Joseph B. Soloveitchik, Halakhic Man Jewish Publication Society, 1983 p. 101

These texts reflect the tradition’s essential attitude toward work. Work is not just necessary to earn a living, it is a way, perhaps the way, to engage in Torah. Thus the very verse that is often understood to mean that we should engage in Torah study continuously–day and night–is reinterpreted to refer not to Torah study but to living a life of Torah. Why? Because it is impossible in the “real” world to spend all of one’s time in Torah study.
The Torah is meant to be lived, not studied. We are to meditate on it day and night, night and day, not by withdrawing from the world into the beit midrash, “the house of study,” but rather by engaging fully in the world while meditating on the Torah and its teaching regarding honesty and living with awareness.
