Avot6: 7
גְּדוֹלָה תוֹרָה שֶׁהִיא נוֹתֶנֶת חַיִּים לְעֹשֶׂיהָ בָּעוֹלָם הַזֶּה וּבָעוֹלָם הַבָּא, שֶׁנֶּאֱמַר: ”כִּי־חַיִּים הֵם לְמֹצְאֵיהֶם וּלְכָל־בְּשָׂרוֹ מַרְפֵּא”; וְאוֹמֵר: ”רִפְאוּת תְּהִי לְשָׁרֶךָ וְשִׁקּוּי לְעַצְמוֹתֶיךָ”; וְאוֹמֵר: ”עֵץ־חַיִּים הִיא לַמַּחֲזִיקִים בָּהּ וְתוֹמְכֶיהָ מְאֻשָּׁר”; וְאוֹמֵר, "כִּי לִוְיַת חֵן הֵם לְרֹאשֶׁךָ וַעֲנָקִים לְגַרְגְּרֹתֶיךָ"; וְאוֹמֵר: ”תִּתֵּן לְרֹאשְׁךָ לִוְיַת־חֵן עֲטֶרֶת תִּפְאֶרֶת תְּמַגְּנֶ÷ָ”; וְאוֹמֵר: ”כִּי־בִי יִרְבּוּ יָמֶיךָ וְיוֹסִיפוּ לְךָ שְׁנוֹת חַיִּים”. וְאוֹמֵר: ”אֹרֶךְ יָמִים בִּימִינָהּ בִּשְׂמֹאולָהּ עֹשֶׁר וְכָבוֹד”; וְאוֹמֵר, "כִּי אֹרֶךְ יָמִים וּשְׁנוֹת חַיִּים וְשָׁלוֹם יוֹסִיפוּ לָךְ”. וְאוֹמֵר: דְּרָכֶיהָ דַרְכֵי נֹעַם וְכָל נְתִיבוֹתֶיהָ שָׁלוֹם.
Great is Torah, for it confers life on its practitioners in this world and in the World to Come, as it states: For they are life to those who find them and healing for all his flesh. And it states: It will be health to your navel and marrow to your bones. And it states: It is a tree of life to those who grasp it and its supporters are fortunate. And it states: For they are an adornment of grace for your head and a chain for your neck. And it states: It will set an adornment of grace upon your head, it will bestow a crown of splendor upon you. And it states: For through me your days will be increased, and they will increase years of life for you. And it states: Length of days is at its right; at its left, wealth and honor. And it states: For they add to you length of days and years of life and peace. And it states: Its ways are ways of pleasantness and all its pathways are peace.
