Halacha 1א׳
הַקוֹשֵׁר קֶשֶׁר שֶׁל קַיָּמָא וְהוּא מַעֲשֵׂה אֻמָּן חַיָּב. כְּגוֹן קֶשֶׁר הַגַּמָּלִין וְקֶשֶׁר הַסַּפָּנִין וְקִשְׁרֵי רְצוּעוֹת מִנְעָל וְסַנְדָּל שֶׁקּוֹשְׁרִין הָרַצְעָנִין בִּשְׁעַת עֲשִׂיָּתָן. וְכֵן כָּל כַּיּוֹצֵא בָּזֶה. אֲבָל הַקּוֹשֵׁר קֶשֶׁר שֶׁל קַיָּמָא וְאֵינוֹ מַעֲשֵׂה אֻמָּן פָּטוּר. וְקֶשֶׁר שֶׁאֵינוֹ שֶׁל קַיָּמָא וְאֵינוֹ מַעֲשֵׂה אֻמָּן מֻתָּר לְקָשְׁרוֹ לְכַתְּחִלָּה:
One who ties a permanent knot and it is the work of a craftsman is liable – such as if the tied a camel-driver’s knot, a sailor’s knot or the knots that strap-makers make for shoes and sandals when they make them. And likewise anything that is similar to this. But one who ties a permanent knot but it is not the work of a craftsman is exempt. And it is permitted from the outset to tie an impermanent knot that is not the work of a craftsman.
Halacha 2ב׳
כֵּיצַד. נִפְסְקָה לוֹ רְצוּעָה וּקְשָׁרָהּ, נִפְסַק הַחֶבֶל וּקְשָׁרוֹ, אוֹ שֶׁקָּשַׁר חֶבֶל בִּדְלִי אוֹ שֶׁקָּשַׁר רֶסֶן בְּהֵמָה הֲרֵי זֶה פָּטוּר. וְכֵן כָּל כַּיּוֹצֵא בְּאֵלּוּ הַקְּשָׁרִים שֶׁהֵן מַעֲשֵׂה הֶדְיוֹט וְכָל אָדָם קוֹשֵׁר אוֹתָן לְקַיָּמָא. וְכָל קֶשֶׁר שֶׁאֵינוֹ שֶׁל קַיָּמָא אִם קְשָׁרוֹ קֶשֶׁר אֻמָּן הֲרֵי זֶה אָסוּר:
How is this? If his strap undid and he tied it; his rope undid and he tied it; or he tied a rope to a bucket; or he tied a bridle to an animal – he is certainly exempt. Likewise anything that is similar to these knots that are the work of an amateur, such that every man ties them [to be] permanent. And if he ties any impermanent knot with a knot that is the work of a craftsman, it is surely forbidden.
Halacha 3ג׳
קוֹשֶׁרֶת אִשָּׁה מִפְתְּחֵי הֶחָלוּק אַף עַל פִּי שֶׁיֵּשׁ לוֹ שְׁנֵי פְּתָחִים, וְחוּטֵי סְבָכָה אַף עַל פִּי שֶׁהוּא רָפוּי בְּרֹאשָׁהּ, וּרְצוּעוֹת מִנְעָל וְסַנְדָּל שֶׁקּוֹשְׁרִין אוֹתָן עַל הָרֶגֶל בִּשְׁעַת מַלְבּוּשׁ, וְנוֹדוֹת יַיִן וְשֶׁמֶן אַף עַל פִּי שֶׁיֵּשׁ לוֹ שְׁתֵּי אָזְנַיִם, וּקְדֵרָה שֶׁל בָּשָׂר אַף עַל פִּי שֶׁיְּכוֹלָה לְהוֹצִיא הַבָּשָׂר וְלֹא תַּתִּיר הַקֶּשֶׁר. וְקוֹשְׁרִין דְּלִי בִּמְשִׁיחָה אוֹ בְּאַבְנֵט וְכַיּוֹצֵא בּוֹ אֲבָל לֹא בְּחֶבֶל. וְקוֹשְׁרִין לִפְנֵי הַבְּהֵמָה אוֹ בְּרַגְלָהּ בִּשְׁבִיל שֶׁלֹּא תֵּצֵא אַף עַל פִּי שֶׁיֵּשׁ לָהּ שְׁנֵי אִסָּרוֹת. וְחֶבֶל שֶׁהָיָה קָשׁוּר בַּפָּרָה קוֹשְׁרוֹ בָּאֵבוּס. הָיָה קָשׁוּר בָּאֵבוּס קוֹשְׁרוֹ בַּפָּרָה. אֲבָל לֹא יָבִיא חֶבֶל מִתּוֹךְ בֵּיתוֹ וְיִקְשֹׁר בַּפָּרָה וּבָאֵבוּס. וְאִם הָיָה חֶבֶל גַּרְדִּי שֶׁמֻּתָּר לְטַלְטְלוֹ הֲרֵי זֶה מֵבִיא וְקוֹשֵׁר בַּפָּרָה וּבָאֵבוּס. מִפְּנֵי שֶׁכָּל אֵלּוּ הַקְּשָׁרִים מַעֲשֵׂה הֶדְיוֹט הֵן וְאֵינָן שֶׁל קַיָּמָא אֶלָּא פַּעַם קוֹשֵׁר וּפַעַם מַתִּיר וּלְפִיכָךְ מֻתָּר לִקְשֹׁר אוֹתָן לְכַתְּחִלָּה. חוֹתָלוֹת שֶׁל תְּמָרִים וְשֶׁל גְּרוֹגָרוֹת מַתִּיר וּמַפְקִיעַ וְחוֹתֵךְ וְנוֹטֵל וְאוֹכֵל:
When getting dressed, a woman may tie the opening of her robe, even though it has two openings (and so the one might have been considered a permanent knot); the strings of her hairnet, even though it is loose on her head (and hence might also have been considered permanent); or the straps of a shoe or a sandal. [She may also tie] wine or oil jugs, even though it has two spouts; and [a garment over] a pot of meat, even though she can take the meat out without untying the knot. We may tie a pail with a cord or a belt and that which is similar to it, but not with a rope. We may tie [a rope across an entrance] before an animal or to its leg so that it will not go out, even though it has two ropes. And he can tie a cow to a trough with a rope that was tied to the cow, or tie the trough to the cow with a rope that was tied to the trough. But he may not bring a rope from his house and tie it to the cow and the trough. However if it was a weaver’s cord that is permitted to carry, he may surely bring it and tie it to the cow and the trough. [One may do all of this] because all of these knots are the work of an amateur and not permanent, but rather [something that] sometimes he ties and sometimes he unties. And therefore it is permissible to tie them at the outset. One may untie wrappers of dates and dried figs; and split, cut, take and eat [them].
