Before we begin:
What in your mind is the appropriate punishment/response for someone who has desecrated the Sabbath?
שֵׁ֣שֶׁת יָמִים֮ תֵּעָשֶׂ֣ה מְלָאכָה֒ וּבַיּ֣וֹם הַשְּׁבִיעִ֗י יִהְיֶ֨ה לָכֶ֥ם קֹ֛דֶשׁ שַׁבַּ֥ת שַׁבָּת֖וֹן לַיהֹוָ֑ה כׇּל־הָעֹשֶׂ֥ה ב֛וֹ מְלָאכָ֖ה יוּמָֽת׃
On six days work may be done, but on the seventh day you shall have a sabbath of complete rest, holy to יהוה; whoever does any work on it shall be put to death.
(יב) וַיֹּ֥אמֶר יְהֹוָ֖ה אֶל־מֹשֶׁ֥ה לֵּאמֹֽר׃ (יג) וְאַתָּ֞ה דַּבֵּ֨ר אֶל־בְּנֵ֤י יִשְׂרָאֵל֙ לֵאמֹ֔ר אַ֥ךְ אֶת־שַׁבְּתֹתַ֖י תִּשְׁמֹ֑רוּ כִּי֩ א֨וֹת הִ֜וא בֵּינִ֤י וּבֵֽינֵיכֶם֙ לְדֹרֹ֣תֵיכֶ֔ם לָדַ֕עַת כִּ֛י אֲנִ֥י יְהֹוָ֖ה מְקַדִּשְׁכֶֽם׃ (יד) וּשְׁמַרְתֶּם֙ אֶת־הַשַּׁבָּ֔ת כִּ֛י קֹ֥דֶשׁ הִ֖וא לָכֶ֑ם מְחַֽלְלֶ֙יהָ֙ מ֣וֹת יוּמָ֔ת כִּ֗י כׇּל־הָעֹשֶׂ֥ה בָהּ֙ מְלָאכָ֔ה וְנִכְרְתָ֛ה הַנֶּ֥פֶשׁ הַהִ֖וא מִקֶּ֥רֶב עַמֶּֽיהָ׃ (טו) שֵׁ֣שֶׁת יָמִים֮ יֵעָשֶׂ֣ה מְלָאכָה֒ וּבַיּ֣וֹם הַשְּׁבִיעִ֗י שַׁבַּ֧ת שַׁבָּת֛וֹן קֹ֖דֶשׁ לַיהֹוָ֑ה כׇּל־הָעֹשֶׂ֧ה מְלָאכָ֛ה בְּי֥וֹם הַשַּׁבָּ֖ת מ֥וֹת יוּמָֽת׃ (טז) וְשָׁמְר֥וּ בְנֵֽי־יִשְׂרָאֵ֖ל אֶת־הַשַּׁבָּ֑ת לַעֲשׂ֧וֹת אֶת־הַשַּׁבָּ֛ת לְדֹרֹתָ֖ם בְּרִ֥ית עוֹלָֽם׃ (יז) בֵּינִ֗י וּבֵין֙ בְּנֵ֣י יִשְׂרָאֵ֔ל א֥וֹת הִ֖וא לְעֹלָ֑ם כִּי־שֵׁ֣שֶׁת יָמִ֗ים עָשָׂ֤ה יְהֹוָה֙ אֶת־הַשָּׁמַ֣יִם וְאֶת־הָאָ֔רֶץ וּבַיּוֹם֙ הַשְּׁבִיעִ֔י שָׁבַ֖ת וַיִּנָּפַֽשׁ׃ {ס}
(12) And יהוה said to Moses: (13) Speak to the Israelite people and say: Nevertheless, you must keep My sabbaths, for this is a sign between Me and you throughout the ages, that you may know that I יהוה have consecrated you. (14) You shall keep the sabbath, for it is holy for you. One who profanes it shall be put to death: whoever does work on it, that person shall be cut off from among kin. (15) Six days may work be done, but on the seventh day there shall be a sabbath of complete rest, holy to יהוה; whoever does work on the sabbath day shall be put to death. (16) The Israelite people shall keep the sabbath, observing the sabbath throughout the ages as a covenant for all time: (17) it shall be a sign for all time between Me and the people of Israel. For in six days יהוה made heaven and earth, and on the seventh day [God] ceased from work and was refreshed.
Why is one given a capital punishment according to these texts?
What does it mean to be Karet (to be cut off from among kin)?
אבל 'מיתת בית דין' תמצאה בענינים הגדולים אם בהפסד אמונה או בחטא גדול - רצוני לומר ב'עבודה זרה וגילוי עריות ושפיכות דמים' וכל מה שמביא לזה; וב'שבת' - להיותו מקיים אמונת חידוש העולם; ובנביא השקר ו'זקן ממרה' - לרב ההפסד הבא מהם; ו'מכה אביו ואמו' ו'מקלל אביו ואמו' - לרב העזות שיש בו והיותו מפסיד סדר הבית אשר הוא החלק הראשון מן המדינה. אבל 'בן סורר ומורה' הוא בעבור מה שיגיע אליו מענינו מפני שהוא עתיד להרוג על כל פנים; ו'גונב נפש' - מפני שהוא מביא אותו להריגה וכן ה'בא במחתרת' אמנם הכניס עצמו להרוג - כמו שבארו 'ז"ל'. ואלו השלשה - רצוני לומר 'בן סורר ומורה' ו'גונב נפש ומכרו' ו'הבא במחתרת' - בידוע שהם שופכי דמים' בסוף. לא תמצא 'מיתת בית דין' בדבר אחר אלא באלו הדברים הגדולים.
Death by the court of law is decreed in important cases: when faith is undermined, or a great crime is committed, viz., idolatry, incest, murder, or actions that lead to these crimes. It is further decreed for breaking the Sabbath (Exod. 31:15); because the keeping of Sabbath is a confirmation of our belief in the Creation; a false prophet and a rebellious elder are put to death on account of the mischief which they cause; he who strikes his father or his mother is killed on account of his great audacity, and because he undermines the constitution of the family, which is the foundation of the state. A rebellious and disobedient son is put to death (Deut. 21:18 seq.) on account of what he might become, because he will likely be a murderer; he who steals a human being is killed, because he is also prepared to kill him whom he steals (Exod. 21:16). Likewise he who is found breaking into a house is prepared for murder (ibid. 22:1), as our Sages stated. These three, the rebellious and disobedient son, he who steals and sells a human being, and he who breaks into a house, become murderers in the course of time, as is well known. Capital punishment is only decreed for these serious crimes, and in no other case.
Why is the punishment for desecrating Shabbat the same as these other crimes?
Is Shabbat a part of this group or an outlier? Why?
There is also a lesson here that the success of the work performed during the six days of the week depends on the observance of the seventh day as a holy day. The reason is that the Sabbath is the soul of the world.
What does it mean that Shabbat is, "the soul of the world"?
How does Shabbat relate to the rest of the week?
שבת שבתון; this expression alludes to the fact that there are activities and even conversations and thoughts which, though not specifically outlawed by the text, are nevertheless something that interfere with the proper Sabbath observance. We have been told already in Exodus 23,12 וביום השביעי תשבות, that the cessation of work etc., has as its objective קדש לה', that this day is to be holy for the Lord, i.e. we are to make it holy. This means that on the Sabbath we ignore secular matters altogether and devote ourselves to spiritual pursuits, and even the mundane pursuits such as eating festive meals must be perceived as part of our honouring G’d on the Sabbath.
כל העושה מלאכה...יומת. It follows that when someone performs secular tasks on the Sabbath they automatically lose track of the purpose of the Sabbath, hence they deserve to be executed.
Is this necessarily a physical death?
What would this look like as a spiritual death?
Should we / Is it appropriate, to speak of matters of the spirit as those of life and death?
ענין סמיכת שבת למשכן רז"ל אמרו מה שאמרו, אבל צריך ליתן טעם למה באמת המלאכות שהיו במשכן דוקא, חייבים עליהם בשבת. ששת ימים תעשה מלאכה (שמות לה, ב), וכי לא סגי בלאו הכי. ובמכילתא (כי תשא ד"ה ששת ימים) תירץ כשזוכין ישראל אזי מלאכתן נעשית ע"י אחרים לכך כתיב תעשה. גם מתורץ על פי מה שאמרו רז"ל במסכת ברכות (לב, ב) חסידים הראשונים מתוך שהיו חסידים תורתן משתמרת ומלאכתן נעשית מאליהן, וע"כ מזהיר שגם עתה תהיה מכם שתגרום המלאכה יהיה נעשה מאליה אף בימי החול.
Although we are all familiar with the comments of our sages who designated all those categories of work which had to be performed in the construction of the Tabernacle as the basic list of forbidden activities on the Sabbath, we must find a better reason why these activities are forbidden on pain of death. Why did they have to draw a parallel with the construction of the Tabernacle? Would it not have sufficed for the Torah to say: "Six days you shall perform work and on the seventh day you must rest?" The Mechilta on 35,2 claims that if we observe the Sabbath legislation the various items on the list are apt to be performed for us by Gentiles. This is the reason the word "you will perform" is expressed in this verse passively, i.e. "will be performed." We may find historical evidence for the truth of this interpretation in the statement in Berachot that the pious people of earlier generations were able to pursue their Torah study without interruption because others attended to their mundane needs. The sages wanted to point out that even in our time such a state of affairs was possible, i.e. that the work to be performed during the six days could be performed by others for those who devoted themselves to Torah in the proper manner.
How does the idea that much of this work would have been preformed by non-Jews affect your understanding of why these actions carry a capital punishment with them?
