Segment 1א׳

וַיְהִי כְּדַבְּרָהּ אֵלָיו יוֹם יוֹם. רִבִּי אֶלְעָזָר פָּתַח וְאֲמַר, (משלי ו׳:כ״ד) לִשְׁמָרְךָ מֵאֵשֶׁת רָע וְגו', זַכָּאִין אִינוּן צַדִּיקַיָּא, דְּיָדְעֵי אָרְחוֹי דְּקוּדְשָׁא בְּרִיךְ הוּא, לְמֵיזַל בְּהוּ. בְּגִין דְּאִינוּן מִשְׁתַּדְּלֵי בְּאוֹרַיְיתָא יְמָמָא וְלֵילְיָא. דְּכָל מַאן דְּאִשְׁתַּדַּל בְּאוֹרַיְיתָא יוֹמֵי וְלֵילֵי, אַחְסִין תְּרֵין עָלְמִין, עַלְמָא עִלָּאָה, וְעַלְמָא תַּתָּאָה. אַחְסִין הַאי עַלְמָא, אַף עַל גַּב דְּלָא אִתְעַסַּק בָּהּ בַּר נָשׁ לִשְׁמָהּ, וְאַחְסִין הַהוּא עַלְמָא עִלָּאָה, כַּד אִתְעַסַּק בָּהּ בַּר נָשׁ לִשְׁמָהּ.

AND IT CAME TO PASS, AS SHE SPOKE TO JOSEPH DAY BY DAY. R. Eleazar discoursed on the verse: To keep thee from the evil woman, etc. (Prov. 6, 24). ‘Happy’, he said, ‘are the righteous who know the ways of the Almighty and follow them, since they devote themselves to the Torah day and night; for whoso devotes himself to the Torah day and night inherits two worlds, the upper world and the world below. He inherits this world, even if he does not study the Torah for its own sake; and he inherits the other world, if he does study the Torah for its own sake;

Segment 2ב׳

תָּא חֲזֵי, מַה כְּתִיב, (משלי ג׳:ט״ז) אֹרֶךְ יָמִים בִּימִינָהּ בִּשְׂמֹאלָהּ עשֶׁר וְכָבוֹד. אֹרֶךְ יָמִים בִּימִינָהּ, מַאן דְּאָזִיל לִימִינָא דְאוֹרַיְיתָא, אָרְכָא דְחַיִּין אִיהוּ לְעַלְמָא דְאָתֵי. דְּזָכֵי תַּמָּן לִיקָרָא דְאוֹרַיְיתָא, דְּאִיהוּ יְקָרָא וְכִתְרָא, לְאִתְעַטְּרָא עַל כֹּלָּא. דְּכִתְרָא דְאוֹרַיְיתָא בְּהַהוּא עַלְמָא אִיהוּ. בִּשְׂמֹאלָהּ עשֶׁר וְכָבוֹד, בְּהַאי עַלְמָא, דְּאַף עַל גַּב דְּלָא אִתְעַסַּק בָּהּ לִשְׁמָהּ, זָכֵי בְּהַאי עַלְמָא בְּעוּתְרָא וִיקָרָא.

and he inherits the other world, if he does study the Torah for its own sake. So it is written: “Length of days is in her right hand, in her left hand are riches and honour” (Ibid. 3, 16); that is, whoever walks to the right of the Torah, for him she is length of life in the world to come, where he will be invested with the glory of the Torah, which is the truest glory and the crown of crowns; for the crown of the Torah is in the other world; but “in her left hand are riches and honour”, to wit, in this world; even for him who does not study it for its own sake.

Segment 3ג׳

דְּהָא רִבִּי חִיָּיא כַּד אֲתָא מֵהָתָם לְאַרְעָא דְיִשְׂרָאֵל, קָרָא בְּאוֹרַיְיתָא, עַד דְּהֲווּ אַנְפּוֹי נְהִירִין כְּשִׁמְשָׁא. וְכַד הֲווּ קָיְימִין קַמֵּיהּ כָּל אִינוּן דְּלָעָאן בְּאוֹרַיְיתָא. הֲוָה אָמַר, דָּא אִשְׁתַּדַּל בְּאוֹרַיְיתָא לִשְׁמָהּ, וְדָא לָא אִשְׁתַּדַּל לִשְׁמָהּ, וְהֲוָה צַלֵּי עַל הַהוּא דְּאִתְעַסַּק לִשְׁמָהּ, דְּלֶיהוֵי הָכִי תָּדִיר, וְיִזְכֵּי לְעַלְמָא דְאָתֵי. וְצַלֵּי עַל הַהוּא דְּלָא אִתְעַסַּק בָּהּ לִשְׁמָהּ, דְּיֵיתֵי לְאִתְעַסְּקָא בָּהּ לִשְׁמָהּ, וְיִזְכֵּי לְחַיֵּי עָלְמָא.

When R. Hiya came from Babylonia to the Land of Israel he studied the Torah until his face shone like the sun, and when the students of the Torah stood up before him he would say: “This one studies the Torah for its own sake, this one does not study the Torah for its own sake.” For the former he would pray that they should always retain that frame of mind and so merit the world to come; for the latter he prayed that their heart should be changed so that they should study the Torah for its own sake and merit life everlasting.
