הלכה אויף מלכים א 2:26

וּלְאֶבְיָתָ֨ר הַכֹּהֵ֜ן אָמַ֣ר הַמֶּ֗לֶךְ עֲנָתֹת֙ לֵ֣ךְ עַל־שָׂדֶ֔יךָ כִּ֛י אִ֥ישׁ מָ֖וֶת אָ֑תָּה וּבַיּ֨וֹם הַזֶּ֜ה לֹ֣א אֲמִיתֶ֗ךָ כִּֽי־נָשָׂ֜אתָ אֶת־אֲר֨וֹן אֲדֹנָ֤י יְהֹוִה֙ לִפְנֵי֙ דָּוִ֣ד אָבִ֔י וְכִ֣י הִתְעַנִּ֔יתָ בְּכֹ֥ל אֲשֶֽׁר־הִתְעַנָּ֖ה אָבִֽי׃

און צו אבֿיתר דעם כּהן האָט דער מלך געזאָגט: גײ קײן ענָתות צו דײַנע פֿעלדער, װאָרום דעם טױט ביסטו װערט, אָבער הײַנטיקן טאָג װעל איך דיך ניט טײטן, װײַל דו האָסט געטראָגן דעם אָרון פֿון גאָט דעם האַר פֿון מײַן פֿאָטער דָוִדן, און װײַל דו האָסט זיך געפּלאָגט אין אַלץ װאָס מײַן פֿאָטער האָט זיך געפּלאָגט.

Mishneh Torah, Rest

It is forbidden to bathe on Yom Kippur — whether with hot water or with cold water; whether his whole body or a single limb. It is even forbidden to put [one's] small finger into water. However, the king and a bride may wash their faces — the bride so she will not be disgusting to her husband; and the king so [people] will see his beauty, as it is stated (Isaiah 33:17), "Your eyes shall see the king in his beauty." For how long [after her wedding] is she called a bride? Thirty days.

Mishneh Torah, Rest

It is forbidden to wear shoes and sandals even on one [of] his feet. But it is permissible to go out with a sandal of cork, or of reed or [of that] that which is similar to them. One may wrap a cloth around his feet and go out with it; for the hardness of the earth surely reaches his feet and he feels that he is barefoot. Even though infants are permitted with regards to eating, drinking, washing, and anointing, we prevent them from [wearing] shoes and sandals.
