(1) The Sages stated a significant principle with regard to the halakhot of Shabbat: One who forgets the essence of Shabbat, i.e., one who is entirely ignorant of the mitzva of Shabbat according to Torah law, and performed numerous prohibited labors on multiple Shabbatot, is liable to bring only one sin-offering for all those labors when he becomes aware that those actions were prohibited. One who knows the essence of Shabbat but forgets which day is Shabbat, i.e., one who lost track of the days of the week, and performs numerous prohibited labors on multiple Shabbatot is liable to bring a sin-offering for each Shabbat when he becomes aware that he performed those actions on Shabbat. One who is aware that the day is Shabbat but temporarily forgot that certain labors were prohibited and performed numerous prohibited labors on multiple Shabbatot is liable to bring a sin-offering for each and every primary category of labor that he performed. One who performs numerous prohibited labors subsumed under a single category of labor is liable to bring only one sin-offering.
(2) This fundamental mishna enumerates those who perform the primary categories of labor prohibited on Shabbat, which number forty-less-one. They are grouped in accordance with their function: One who sows, and one who plows, and one who reaps, and one who gathers sheaves into a pile, and one who threshes, removing the kernel from the husk, and one who winnows threshed grain in the wind, and one who selects the inedible waste from the edible, and one who grinds, and one who sifts the flour in a sieve, and one who kneads dough, and one who bakes. Additional primary categories of prohibited labor are the following: One who shears wool, and one who whitens it, and one who combs the fleece and straightens it, and one who dyes it, and one who spins the wool, and one who stretches the threads of the warp in the loom, and one who constructs two meshes, tying the threads of the warp to the base of the loom, and one who weaves two threads, and one who severs two threads for constructive purposes, and one who ties a knot, and one who unties a knot, and one who sews two stitches with a needle, as well as one who tears a fabric in order to sew two stitches. One who traps a deer, or any living creature, and one who slaughters it, and one who flays it, and one who salts its hide, a step in the tanning process, and one who tans its hide, and one who smooths it, removing hairs and veins, and one who cuts it into measured parts. One who writes two letters and one who erases in order to write two letters. One who builds a structure, and one who dismantles it, one who extinguishes a fire, and one who kindles a fire. One who strikes a blow with a hammer to complete the production process of a vessel (Rabbeinu Ḥananel), and one who carries out an object from domain to domain. All these are primary categories of labor, and they number forty-less-one.
(א) ואתה דבר אל בני ישראל. וְאַתָּה אַעַ"פִּ שֶׁהִפְקַדְתִּיךָ לְצַוּוֹתָם עַל מְלֶאכֶת הַמִּשְׁכָּן, אַל יֵקַל בְּעֵינֶיךָ לִדְחוֹת אֶת הַשַּׁבָּת מִפְּנֵי אוֹתָהּ מְלָאכָה: (ב) אך את שבתתי תשמרו. אַעַ"פִּ שֶׁתִּהְיוּ רְדוּפִין וּזְרִיזִין בִּזְרִיזוּת הַמְּלָאכָה, שַׁבָּת אַל תִּדָּחֶה מִפָּנֶיהָ, כָּל אַכִין וְרַקִּין מִעוּטִין – לְמַעֵט שַׁבָּת מִמְּלֶאכֶת הַמִּשְׁכָּן:
(1) ואתה דבר אל בני ישראל SPEAK THOU ALSO UNTO THE CHILDREN OF ISRAEL — AND thou, although I have given thee charge to command them concerning the work of the Tabernacle let it not appear a light thing to thee to set the Sabbath aside on account of that work. (2) אך את שבתתי תשמרו BUT NEVERTHELESS MY SABBATHS SHALL YE KEEP — Even though you be anxious and alert to do the work promptly the Sabbath nevertheless you must not set aside on its account. The words אך and רק wherever they occur in Scripture have limitative force (Rosh Hashanah 17b; cf. Rashi on Rosh Hashanah 17b on אכין ורקין). Here Scripture intends by the word אך to except the Sabbath from the days on which the work of the Tabernacle may be done.
