בָּעֵ֣ת הַהִ֗יא דִּבֶּ֣ר יְהוָה֮ בְּיַ֣ד יְשַׁעְיָ֣הוּ בֶן־אָמוֹץ֮ לֵאמֹר֒ לֵ֗ךְ וּפִתַּחְתָּ֤ הַשַּׂק֙ מֵעַ֣ל מָתְנֶ֔יךָ וְנַעַלְךָ֥ תַחֲלֹ֖ץ מֵעַ֣ל רַגְלֶ֑יךָ וַיַּ֣עַשׂ כֵּ֔ן הָלֹ֖ךְ עָר֥וֹם וְיָחֵֽף׃ (ס)
En aquel tiempo habló SEÑOR por Isaías hijo de Amoz, diciendo: Ve, y quita el saco de tus lomos, y descalza los zapatos de tus pies. E hízolo así, andando desnudo y descalzo.
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.
