בָּעֵ֣ת הַהִ֗יא דִּבֶּ֣ר יְהוָה֮ בְּיַ֣ד יְשַׁעְיָ֣הוּ בֶן־אָמוֹץ֮ לֵאמֹר֒ לֵ֗ךְ וּפִתַּחְתָּ֤ הַשַּׂק֙ מֵעַ֣ל מָתְנֶ֔יךָ וְנַעַלְךָ֥ תַחֲלֹ֖ץ מֵעַ֣ל רַגְלֶ֑יךָ וַיַּ֣עַשׂ כֵּ֔ן הָלֹ֖ךְ עָר֥וֹם וְיָחֵֽף׃ (ס)
à cette époque, le Seigneur, s’adressant à Isaïe, fils d’Amoç, lui parla ainsi: "Va, dénoue le cilice qui couvre tes reins et ôte les souliers de tes pieds." Se conformant à cet ordre, le prophète alla dévêtu et déchaussé.
Mishnah Megillah
A child may read in the Torah and translate, but he may not pass before the ark or lift up his hands. A person in rags may lead the responsive reading of the Shema and translate, but he may not read in the Torah, pass before the ark, or lift up his hands. A blind man may lead the responsive reading of the Shema and translate. Rabbi Judah says: one who has never seen the light from his birth may not lead the responsive reading of the Shema.
