Se’if 4ד׳

הַהוֹלֵךְ מִמָּקוֹם שֶׁעוֹשִׂין לְמָקוֹם שֶׁאֵין עוֹשִׂין, לֹא יַעֲשֶׂה בְּיִשּׁוּב מִפְּנֵי הַמַּחֲלֹקֶת; אֲבָל עוֹשֶׂה הוּא בַּמִּדְבָּר. וְהַהוֹלֵךְ מִמָּקוֹם שֶׁאֵין עוֹשִׂים לְמָקוֹם שֶׁעוֹשִׂין, לֹא יַעֲשֶׂה. וְנוֹתְנִים עָלָיו חֻמְרֵי מָקוֹם שֶׁיָּצָא מִשָּׁם וְחֻמְרֵי מָקוֹם שֶׁהָלַךְ לְשָׁם, וְאַף עַל פִּי כֵן לֹא יִתְרָאֶה בִּפְנֵיהֶם שֶׁהוּא בָּטֵל, מִפְּנֵי אִסוּר לְעוֹלָם אַל יְשַׁנֶּה אָדָם מִפְּנֵי הַמַּחֲלֹקֶת. וְכֵן מִי שֶׁדַּעְתּוֹ לַחֲזֹר לִמְקוֹמוֹ, נוֹהֵג כְּאַנְשֵׁי מְקוֹמוֹ בֵּין לְהָקֵל בֵּין לְהַחְמִיר, וְהוּא שֶׁלֹּא יִתְרָאֶה בִּפְנֵי אַנְשֵׁי הַמָּקוֹם שֶׁהוּא בּוֹ, מִפְּנֵי הַמַּחֲלֹקֶת.

One who goes from a place where they do work to a place where they do not may not do it in a settled place, on account of dispute; but he may do it in the wilderness. And one who goes from a place where they do not do work to a place where they do may not do it. And they lay upon him the stringencies of the place he left and the stringencies of the place he has gone to; and even so, he should not show himself before them as idle on account of the prohibition. A man should never deviate, on account of dispute. And likewise one who intends to return to his own place conducts himself like the people of his place, whether to be lenient or to be stringent, provided that he does not show himself before the people of the place where he is, on account of dispute.

Se’if 5ה׳

אֲפִלּוּ בְּמָקוֹם שֶׁנָּהֲגוּ לַעֲשׂוֹת, לֹא יַתְחִיל בִּתְחִלַּת מְלָאכָה בְּאַרְבָּעָה עָשָׂר, אַף עַל פִּי שֶׁהוּא יָכוֹל לְגָמְרָהּ קֹדֶם חֲצוֹת, אֶלָּא שְׁלֹשָׁה אֻמָּנֻיּוֹת בִּלְבַד הֵם שֶׁמַּתְחִילִים בָּהֶם בְּמָקוֹם שֶׁנָּהֲגוּ לַעֲשׂוֹת וְעוֹשִׂין עַד חֲצוֹת, וְאֵלּוּ הֵם: הַחַיָּטִים וְהַסַפָּרִים וְהַכּוֹבְסִים; אֲבָל שְׁאָר אֻמָּנֻיּוֹת, אִם הִתְחִיל בָּהֶם קֹדֶם אַרְבָּעָה עָשָׂר הוּא שֶׁיִּגְמֹר עַד חֲצוֹת. הַגָּה: וְיֵשׁ מְקִלִּין לוֹמַר שֶׁשְּׁלֹשָׁה אֻמָּנֻיּוֹת הַנִּזְכָּרִים מַתְחִילִין וְעוֹשִׂין עַד חֲצוֹת אֲפִלּוּ בְּמָקוֹם שֶׁנָּהֲגוּ שֶׁלֹּא לַעֲשׂוֹת, וְאִם הִתְחִיל מִבְּעוֹד יוֹם בִּשְׁאָר אֻמָּנוּת וְהוּא לְצֹרֶךְ הַמּוֹעֵד, עוֹשִׂין עַד חֲצוֹת, וְהָכֵי נָהוּג (טוּר בְּשֵׁם הָרֹא"שׁ).

Even in a place where they were accustomed to do work, one may not begin a new piece of work on the fourteenth, even though he can finish it before midday; only three crafts are there which one may begin in a place where they were accustomed to do work, and do until midday, and these are they: the tailors, the barbers and the launderers. But other crafts — if he began them before the fourteenth, he may finish them until midday. Hagah [Rema]: And there are those who are lenient, saying that the three crafts mentioned begin and work until midday even in a place where they were accustomed not to do work; and that if he began another craft while it was still day, and it is for the need of the festival, he works until midday; and so is the custom (Tur in the name of the Rosh).
