הלכות שביתת עשור ג׳Rest on the Tenth of Tishrei 3

Halacha 1א׳

אָסוּר לִרְחֹץ בְּיוֹם הַכִּפּוּרִים בֵּין בְּחַמִּין בֵּין בְּצוֹנֵן. בֵּין כָּל גּוּפוֹ בֵּין אֵיבָר אֶחָד אֲפִלּוּ אֶצְבַּע קְטַנָּה אָסוּר לְהוֹשִׁיטָהּ בַּמַּיִם. וְהַמֶּלֶךְ וְהַכַּלָּה רוֹחֲצִין אֶת פְּנֵיהֶן. כַּלָּה כְּדֵי שֶׁלֹּא תִּתְגַּנֶּה עַל בַּעְלָהּ. וְהַמֶּלֶךְ כְּדֵי שֶׁיֵּרָאֶה בְּיָפְיוֹ שֶׁנֶּאֱמַר (ישעיה לג יז) "מֶלֶךְ בְּיָפְיוֹ תֶּחֱזֶינָה עֵינֶיךָ". וְעַד כַּמָּה נִקְרֵאת כַּלָּה עַד שְׁלֹשִׁים יוֹם:

It is forbidden to wash oneself on the Day of Atonement whether with hot water or with cold water, whether his whole body or a single limb. It is forbidden to put even one's pinky finger into water. However, the king and a bride wash their faces--the bride so she will not be disgraceful to her husband and the king so [people] will see his beauty, as it says, "your eyes shall see the king in his beauty." For how long [after her wedding] is she called a bride? Thirty days.

Halacha 2ב׳

מִי שֶׁהָיָה מְלֻכְלָךְ בְּצוֹאָה אוֹ טִיט רוֹחֵץ מְקוֹם הַטִּנֹּפֶת כְּדַרְכּוֹ וְאֵינוֹ חוֹשֵׁשׁ. וּמְדִיחָה אִשָּׁה יָדָהּ אַחַת בְּמַיִם וְנוֹתֶנֶת פַּת לְתִינוֹק. וְהַחוֹלֶה רוֹחֵץ כְּדַרְכּוֹ אַף עַל פִּי שֶׁאֵינוֹ מְסֻכָּן. וְכָל חַיָּבֵי טְבִילוֹת טוֹבְלִין כְּדַרְכָּן בֵּין בְּתִשְׁעָה בְּאָב בֵּין בְּיוֹם הַכִּפּוּרִים:

One who was dirty with excrement or mud may wash the dirty place in his usual way without worrying [about violating the prohibition]. A woman can heat up one of her hands in water and give bread to a baby. An ill person may wash in his usual way even if he is not in danger [of his life]. All those who are obligated to immerse [in a ritual bath] immerse in their usual way, whether on the Ninth of Av or the Day of Atonement.

Halacha 3ג׳

מִי שֶׁרָאָה קֶרִי בַּזְּמַן הַזֶּה בְּיוֹם הַכִּפּוּרִים. אִם לַח הוּא מְקַנֵּחַ בְּמַפָּה וְדַיּוֹ. וְאִם יָבֵשׁ הוּא אוֹ שֶׁנִּתְלַכְלֵךְ רוֹחֵץ מְקוֹמוֹת הַמְלֻכְלָכִין בִּלְבַד וּמִתְפַּלֵּל. וְאָסוּר לוֹ לִרְחֹץ כָּל גּוּפוֹ אוֹ לִטְבּל. שֶׁאֵין הַטּוֹבֵל בַּזְּמַן הַזֶּה טָהוֹר מִפְּנֵי טֻמְאַת מֵת וְאֵין הָרְחִיצָה מִקֶּרִי לִתְפִלָּה בַּזְּמַן הַזֶּה אֶלָּא מִנְהָג וְאֵין מִנְהָג לְבַטֵּל דָּבָר הָאָסוּר אֶלָּא לֶאֱסֹר אֶת הַמֻּתָּר. וְלֹא אָמְרוּ שֶׁהָרוֹאֶה קֶרִי בְּיוֹם הַכִּפּוּרִים טוֹבֵל אֶלָּא כְּשֶׁתִּקְּנוּ טְבִילָה לְבַעֲלֵי קְרָיִין וּכְבָר בֵּאַרְנוּ שֶׁבָּטְלָה תַּקָּנָה זוֹ:

One who has a seminal emission on the Day of Atonement nowadays: If it is moist, he wipes it with a napkin, and that is enough. If it is dry or [he] became dirty [with it], he washes the dirty places alone and [then] he may pray. It is forbidden for him to wash his whole body or immerse. For one who immerses nowadays is not pure--due to impurity from exposure to dead people [which everyone is assumed to have]--and washing [i.e. immersing] for a seminal emission nowadays is only a custom. And a custom cannot permit something that is forbidden, rather it can only forbid something that is permissible. They [the rabbis] said that one who has a seminal emission on the Day of Atonement immerses only when there was a rule that those who had seminal emissions must immerse [the rule was made at the time of Ezra], and we already explained that this rule was cancelled.
