רַבִּי אֱלִיעֶזֶר אוֹמֵר, הָאוֹרֵג שְׁלשָׁה חוּטִין בַּתְּחִלָּה וְאַחַת עַל הָאָרִיג, חַיָּב. וַחֲכָמִים אוֹמְרִים, בֵּין בַּתְּחִלָּה בֵּין בַּסּוֹף, שִׁעוּרוֹ שְׁנֵי חוּטִין:
Rabbi Eliezer says: One who weaves on Shabbat is liable to bring a sin-offering if he wove three threads at the beginning of something new, or if he adds one thread to a preexisting woven fabric. And the Rabbis say: Both at the beginning and at the end, its measure for liability is two threads.
הָעוֹשֶׂה שְׁנֵי בָתֵּי נִירִין בַּנִּירִין, בַּקֵּרוֹס, בַּנָּפָה, בַּכְּבָרָה וּבַסַּל, חַיָּב. וְהַתּוֹפֵר שְׁתֵּי תְפִירוֹת, וְהַקּוֹרֵעַ עַל מְנָת לִתְפֹּר שְׁתֵּי תְפִירוֹת:
One who makes two meshes, i.e., ties the threads of the warp, attaching them to either the nirin or the keiros, which will be explained in the Gemara, in a winnow, sieve, or basket, is liable for making meshes. And one who sews is liable if he sews two stitches. And one who tears is liable if he tears enough fabric in order to sew two stitches to repair it.
הַקּוֹרֵעַ בַּחֲמָתוֹ וְעַל מֵתוֹ, וְכָל הַמְקַלְקְלִין, פְּטוּרִין. וְהַמְקַלְקֵל עַל מְנָת לְתַקֵּן, שִׁעוּרוֹ כַמְתַקֵּן:
One who rends his garment in his anger or in anguish over his dead relative is exempt. And anyone else who performs labors destructively on Shabbat is exempt. And one who performs a labor destructively in order to repair is liable, and his measure for liability is equivalent to the measure for one who performs that labor constructively.
שִׁעוּר הַמְלַבֵּן וְהַמְנַפֵּץ וְהַצּוֹבֵעַ וְהַטּוֹוֶה, כִּמְלֹא רֹחַב הַסִּיט כָּפוּל. וְהָאוֹרֵג שְׁנֵי חוּטִין, שִׁעוּרוֹ כִּמְלֹא הַסִּיט:
The measure that determines liability for one who whitens, or one who combs, or one who dyes, or one who spins wool is the full width of a double sit, which is the distance between the forefinger and the middle finger. And for one who weaves two threads, the measure that determines liability is one sit.
רַבִּי יְהוּדָה אוֹמֵר, הַצָּד צִפּוֹר לַמִּגְדָּל וּצְבִי לַבַּיִת, חַיָּב. וַחֲכָמִים אוֹמְרִים, צִפּוֹר לַמִּגְדָּל, וּצְבִי לַבַּיִת וְלֶחָצֵר וְלַבֵּיבָרִין. רַבָּן שִׁמְעוֹן בֶּן גַּמְלִיאֵל אוֹמֵר, לֹא כָל הַבֵּיבָרִין שָׁוִין. זֶה הַכְּלָל, מְחֻסַּר צִידָה, פָּטוּר, וְשֶׁאֵינוֹ מְחֻסַּר צִידָה, חַיָּב:
Rabbi Yehuda says: One who traps a bird into a closet or cage, and one who traps a deer into a house is liable. The Rabbis say: One is liable for trapping a bird into a closet and for trapping a deer into a garden, or into a courtyard, or into an enclosure [bivar], he is liable. Rabban Shimon ben Gamliel says: Not all enclosures are identical. This is the principle: If the trapping of the animal is inadequate and it is still necessary to pursue and apprehend it, one is not liable. However, if one trapped a deer into an enclosure in which the trapping is not inadequate, he is liable.
צְבִי שֶׁנִּכְנַס לַבַּיִת וְנָעַל אֶחָד בְּפָנָיו, חַיָּב. נָעֲלוּ שְׁנַיִם, פְּטוּרִין. לֹא יָכֹל אֶחָד לִנְעֹל וְנָעֲלוּ שְׁנַיִם, חַיָּבִין. וְרַבִּי שִׁמְעוֹן פּוֹטֵר:
If a deer entered a house on its own and one locked the door before it, he is liable for trapping. If two people locked the door, they are exempt, because neither performed a complete labor. If one person is incapable of locking the door and two people locked it, they are liable because that is the typical manner of performing that labor. And Rabbi Shimon deems them exempt as he holds that two people who perform a single labor are never liable by Torah law.
יָשַׁב הָאֶחָד עַל הַפֶּתַח וְלֹא מִלְּאָהוּ, יָשַׁב הַשֵּׁנִי וּמִלְּאָהוּ, הַשֵּׁנִי חַיָּב. יָשַׁב הָרִאשׁוֹן עַל הַפֶּתַח וּמִלְּאָהוּ, וּבָא הַשֵּׁנִי וְיָשַׁב בְּצִדּוֹ, אַף עַל פִּי שֶׁעָמַד הָרִאשׁוֹן וְהָלַךְ לוֹ, הָרִאשׁוֹן חַיָּב וְהַשֵּׁנִי פָּטוּר. הָא לְמַה זֶּה דוֹמֶה, לְנוֹעֵל אֶת בֵּיתוֹ לְשָׁמְרוֹ וְנִמְצָא צְבִי שָׁמוּר בְּתוֹכוֹ:
If one person sat in the entrance of a courtyard in which there is a deer, but did not fill the entire doorway, and a second person sat and filled it, the second person is liable because he completed the labor of trapping. However, if the first person sat in the doorway and filled it, and a second person came and sat next to him, the first person is liable and the second is exempt even if the first person stood and went away, leaving the second one to secure the deer. The mishna explains: To what is this second person’s action similar? To one who locks his house to secure it, and it turns out a deer that was trapped before Shabbat is also secured inside it. In that case, he is exempt even though he enhances security on the deer, because he did not trap the animal.
