כְּבֹאֲכֶ֣ם הָעִ֣יר כֵּ֣ן תִּמְצְא֣וּן אֹת֡וֹ בְּטֶרֶם֩ יַעֲלֶ֨ה הַבָּמָ֜תָה לֶאֱכֹ֗ל כִּ֠י לֹֽא־יֹאכַ֤ל הָעָם֙ עַד־בֹּא֔וֹ כִּֽי־הוּא֙ יְבָרֵ֣ךְ הַזֶּ֔בַח אַחֲרֵי־כֵ֖ן יֹאכְל֣וּ הַקְּרֻאִ֑ים וְעַתָּ֣ה עֲל֔וּ כִּֽי־אֹת֥וֹ כְהַיּ֖וֹם תִּמְצְא֥וּן אֹתֽוֹ׃
你們一進城，就會遇見他，那時他還沒有上高處去吃祭肉；因為他還沒到，民眾是不會先吃的，要等他為祭物祝福，然後被邀請的人才吃。現在你們上去吧，因為這個時候正好能遇見他。»
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.
