(יב) וְלָמָּה לֹא זָכָה לֵוִי בְּנַחֲלַת אֶרֶץ יִשְׂרָאֵל וּבְבִזָּתָהּ עִם אֶחָיו מִפְּנֵי שֶׁהֻבְדַּל לַעֲבֹד אֶת ה' לְשָׁרְתוֹ וּלְהוֹרוֹת דְּרָכָיו הַיְשָׁרִים וּמִשְׁפָּטָיו הַצַּדִּיקִים לָרַבִּים שֶׁנֶּאֱמַר (דברים לג י) "יוֹרוּ מִשְׁפָּטֶיךָ לְיַעֲקֹב וְתוֹרָתְךָ לְיִשְׂרָאֵל". לְפִיכָךְ הֻבְדְּלוּ מִדַּרְכֵי הָעוֹלָם לֹא עוֹרְכִין מִלְחָמָה כִּשְׁאָר יִשְׂרָאֵל וְלֹא נוֹחֲלִין וְלֹא זוֹכִין לְעַצְמָן בְּכֹחַ גּוּפָן. אֶלָּא הֵם חֵיל הַשֵּׁם שֶׁנֶּאֱמַר (דברים לג יא) "בָּרֵךְ ה' חֵילוֹ". וְהוּא בָּרוּךְ הוּא זוֹכֶה לָהֶם שֶׁנֶּאֱמַר (במדבר יח כ) "אֲנִי חֶלְקְךָ וְנַחֲלָתְךָ":
(12) Why were the Levites not allotted land in Eretz Yisrael or a share in its booty along with their brethren? Because they were singled out to serve the Lord and minister to him, to teach his upright ways and just laws to many people, as it is written: "They shall teach thy laws to Jacob, and thy instruction to Israel" (Deuteronomy 33:10). For this reason, they were separated from worldly affairs: they fought no battles like the rest of Israel; they inherited no land; they won nothing by means of their physical ability. They are indeed the Lord's army, as it is written: "Bless, O Lord, his substance" (11). He, blessed be he, has won them for himself, as it is written: "I am your portion and your share" (Numbers 18:20).
(י) כָּל הַמֵּשִׂים עַל לִבּוֹ שֶׁיַּעֲסֹק בַּתּוֹרָה וְלֹא יַעֲשֶׂה מְלָאכָה וְיִתְפַּרְנֵס מִן הַצְּדָקָה הֲרֵי זֶה חִלֵּל אֶת הַשֵּׁם וּבִזָּה אֶת הַתּוֹרָה וְכִבָּה מֵאוֹר הַדָּת וְגָרַם רָעָה לְעַצְמוֹ וְנָטַל חַיָּיו מִן הָעוֹלָם הַבָּא. לְפִי שֶׁאָסוּר לֵהָנוֹת מִדִּבְרֵי תּוֹרָה בָּעוֹלָם הַזֶּה. אָמְרוּ חֲכָמִים (משנה אבות ד ה) "כָּל הַנֶּהֱנֶה מִדִּבְרֵי תּוֹרָה נָטַל חַיָּיו מִן הָעוֹלָם". וְעוֹד צִוּוּ וְאָמְרוּ (משנה אבות ד ה) "אַל תַּעֲשֵׂם עֲטָרָה לְהִתְגַּדֵּל בָּהֶן וְלֹא קַרְדֹּם לַחְפֹּר בָּהֶן". וְעוֹד צִוּוּ וְאָמְרוּ (משנה אבות א י) "אֱהֹב אֶת הַמְּלָאכָה וּשְׂנָא אֶת הָרַבָּנוּת", (משנה אבות ב ב) "וְכָל תּוֹרָה שֶׁאֵין עִמָּהּ מְלָאכָה סוֹפָהּ בְּטֵלָה וְגוֹרֶרֶת עָוֹן". וְסוֹף אָדָם זֶה שֶׁיְּהֵא מְלַסְטֵם אֶת הַבְּרִיּוֹת:
(10) Nevertheless, whosoever sets his heart to pursue the study of the Torah but do no secular work at all, and permits himself to be supported by charity, behold him, he blasphemed the Name, and degraded the Torah, and shadowed the light of religion, and caused evil to be brought upon himself, and deprived his own life from its share in the world to come; because it is forbidden to enjoy aught in this world in return of the study of the words of the Torah. The sages said: "Whosoever enjoys aught in return of the study of the words of the Torah takes his own life away from the world" (Pirke Abot, 4.7). They have, moreover, commanded and said: "Thou shalt not make them a garland by which to be considered great nor a spade to dig with them" (Ibid.). Again they have commanded and said: "Love manual labor and hate rank". (Pirke Abot, 1.10); whosoever studies the Torah and does not acquire at the same time a manual trade his knowledge of the Torah will be nullified and bring about sin" (Ibid. 2.2.). The end of this will be that he will rob people for his living.10The text is clear enough to absolve Maimonides from forbidding scholars to accept renumeration. It can not be construed to include priests, teachers, Rabbis and other scholars who render services to the public. He only includes such scholars as are doing nothing in return for gifts received by them. This would be enjoying fruit of the Torah in this world. Cairo strenously objects to this law, and supports his objections by authority from Yoma, 35a; Berakot, 17a; Ta’anit 25a; Ketubot, 105a; Gittin 67b; Baba Mezi’a, 84b; Sotah, 21a; Hullin, 134a; Nedarim, 62a.
