Hebrew · Jerusalem Talmud, ed. Guggenheimer (Hebrew/Aramaic)הלכה: יוֹדֵעַ לְנַעְנֵעַ חַיָיב בְּלוּלָב. יוֹדֵעַ לְהִתְעַטֵּף חַיָיב בַּצִּיצִית. יוֹדֵעַ לְדַבֵּר אָבִיו מְלַמְּדוֹ לְשׁוֹן תּוֹרָה. יוֹדֵעַ לִשְׁמוֹר אֶת יָדָיו אוֹכְלִין עַל יָדָיו תְּרוּמָה. אֶת גּוּפוֹ אוֹכְלִין עַל גּוּפוֹ טָהֳרוֹת. אֲבָל אֵינוֹ עוֹבֵר לִפְנֵי הַתֵּיבָה וְאֵינוֹ נוֹשֵׂא אֶת כַּפָּיו וְאֵינוֹ עוֹמֵד עַל הַדּוּכָן עַד שֶׁיִּתְמָלֵא זְקָנוֹ. רִבִּי אוֹמֵר. וְכוּלְּהֵם מִבֶּן עֶשְׂרִים שָׁנָה וּמַעֲלָה. שֶׁנֶּאֱמַר וַיַּעֲמִידוּ אֶת הַלְוִיִּם מִבֶּן עֶשְׂרִים שָׁנָה וָמַעְלָה לְנַצֵּחַ עַל מְלֶאכֶת בֵּית יְי.
English · Heinrich W. GuggenheimerHALAKHAH: If he knows how to move he is obligated for lulav. If he knows how to dress, he is obligated for ṣiṣit. If he knows how to talk, his father teaches him the language of the Torah. If he knows how to keep his hands clean, one eats heave on his hands. If he knows how to keep his body clean, one eats food in purity on his body. But he does not go before the Ark, nor lift his hands, nor stands on the podium, before he grows a beard. Rebbi says, all of them at the age of twenty years, as it is said: They appointed the Levites, twenty years or older, to direct the work of the Eternal’s House.
