תַּלְמִיד שֶׁגָּלָה לְעָרֵי מִקְלָט מַגְלִין רַבּוֹ עִמּוֹ שֶׁנֶּאֱמַר וָחָי עֲשֵׂה לוֹ כְּדֵי שֶׁיִּחְיֶה וְחַיֵּי בַּעֲלֵי חָכְמָה וּמְבַקְּשֶׁיהָ בְּלֹא תַּלְמוּד תּוֹרָה כְּמִיתָה חֲשׁוּבִין. וְכֵן הָרַב שֶׁגָּלָה מַגְלִין יְשִׁיבָתוֹ עִמּוֹ:
A scholar who is exiled to a city of refuge, his teacher is exiled with him, as it says, "[And he shall flee to one of these cities] and live (Deuteronomy 19:5)." Give him [his teacher]in order that he may live and a scholar must have his teacher because without Torah study, one is thought to be dead. Similarly, if a teacher is exiled, his academy is exiled with him.
