וְהָיָ֣ה ׀ עֵ֣קֶב תִּשְׁמְע֗וּן אֵ֤ת הַמִּשְׁפָּטִים֙ הָאֵ֔לֶּה וּשְׁמַרְתֶּ֥ם וַעֲשִׂיתֶ֖ם אֹתָ֑ם וְשָׁמַר֩ יי אֱלֹקֶ֜יךָ לְךָ֗ אֶֽת־הַבְּרִית֙ וְאֶת־הַחֶ֔סֶד אֲשֶׁ֥ר נִשְׁבַּ֖ע לַאֲבֹתֶֽיךָ׃ וַאֲהֵ֣בְךָ֔ וּבֵרַכְךָ֖ וְהִרְבֶּ֑ךָ וּבֵרַ֣ךְ פְּרִֽי־בִטְנְךָ֣ וּפְרִֽי־אַ֠דְמָתֶ֠ךָ דְּגָ֨נְךָ֜ וְתִירֹֽשְׁךָ֣ וְיִצְהָרֶ֗ךָ שְׁגַר־אֲלָפֶ֙יךָ֙ וְעַשְׁתְּרֹ֣ת צֹאנֶ֔ךָ עַ֚ל הָֽאֲדָמָ֔ה אֲשֶׁר־נִשְׁבַּ֥ע לַאֲבֹתֶ֖יךָ לָ֥תֶת לָֽךְ׃ בָּר֥וּךְ תִּֽהְיֶ֖ה מִכׇּל־הָעַמִּ֑ים לֹא־יִהְיֶ֥ה בְךָ֛ עָקָ֥ר וַֽעֲקָרָ֖ה וּבִבְהֶמְתֶּֽךָ׃
וְהֵסִ֧יר יי מִמְּךָ֖ כׇּל־חֹ֑לִי וְכׇל־מַדְוֵי֩ מִצְרַ֨יִם הָרָעִ֜ים אֲשֶׁ֣ר יָדַ֗עְתָּ לֹ֤א יְשִׂימָם֙ בָּ֔ךְ וּנְתָנָ֖ם בְּכׇל־שֹׂנְאֶֽיךָ׃
And if you do obey these rules and observe them carefully, then Adonai your God will maintain faithfully for you the covenant that God made on oath with your ancestors:
God will favor you and bless you and multiply you; God will bless the issue of your womb and the produce of your soil, your new grain and wine and oil, the calving of your herd and the lambing of your flock, in the land that God swore to your ancestors to assign to you.
You shall be blessed above all other peoples: there shall be no sterile male or female among you or among your livestock.
Adonai will ward off from you all sickness; God will not bring upon you any of the dreadful diseases of Egypt, about which you know, but will inflict them upon all your enemies.
(ח) וּשְׁמַרְתֶּם֙ אֶת־כׇּל־הַמִּצְוָ֔ה אֲשֶׁ֛ר אָנֹכִ֥י מְצַוְּךָ֖ הַיּ֑וֹם לְמַ֣עַן תֶּחֶזְק֗וּ וּבָאתֶם֙ וִֽירִשְׁתֶּ֣ם אֶת־הָאָ֔רֶץ אֲשֶׁ֥ר אַתֶּ֛ם עֹבְרִ֥ים שָׁ֖מָּה לְרִשְׁתָּֽהּ׃ (ט) וּלְמַ֨עַן תַּאֲרִ֤יכוּ יָמִים֙ עַל־הָ֣אֲדָמָ֔ה אֲשֶׁר֩ נִשְׁבַּ֨ע יי לַאֲבֹתֵיכֶ֛ם לָתֵ֥ת לָהֶ֖ם וּלְזַרְעָ֑ם אֶ֛רֶץ זָבַ֥ת חָלָ֖ב וּדְבָֽשׁ׃
(8) Keep, therefore, all the Instruction that I enjoin upon you today, so that you may have the strength to enter and take possession of the land that you are about to cross into and possess, (9) and that you may long endure upon the soil that Adonai swore to your ancestors to assign to them and to their heirs, a land flowing with milk and honey.
וְעַתָּה֙ יִשְׂרָאֵ֔ל מָ֚ה יי אֱלֹקֶ֔יךָ שֹׁאֵ֖ל מֵעִמָּ֑ךְ כִּ֣י אִם־לְ֠יִרְאָ֠ה אֶת־יי אֱלֹקֶ֜יךָ לָלֶ֤כֶת בְּכׇל־דְּרָכָיו֙ וּלְאַהֲבָ֣ה אֹת֔וֹ וְלַֽעֲבֹד֙ אֶת־יי אֱלֹקֶ֔יךָ בְּכׇל־לְבָבְךָ֖ וּבְכׇל־נַפְשֶֽׁךָ׃
לִשְׁמֹ֞ר אֶת־מִצְוֺ֤ת יי וְאֶת־חֻקֹּתָ֔יו אֲשֶׁ֛ר אָנֹכִ֥י מְצַוְּךָ֖ הַיּ֑וֹם לְט֖וֹב לָֽךְ׃
And now, O Israel, what does Adonai your God demand of you? Only this: to revere Adonai, to walk only in God's paths, to love Adonai, and to serve your God with all your heart and soul, keeping God’s commandments and laws, which I enjoin upon you today, for your good.
"The 'keeping' is not for free, but rather 'for your good' - in order that you may receive a reward." (Rashi on Deut. 10:13)
וְהָיָ֗ה אִם־שָׁמֹ֤עַ תִּשְׁמְעוּ֙ אֶל־מִצְוֺתַ֔י אֲשֶׁ֧ר אָנֹכִ֛י מְצַוֶּ֥ה אֶתְכֶ֖ם הַיּ֑וֹם לְאַהֲבָ֞ה אֶת־יי אֱלֹֽהֵיכֶם֙ וּלְעׇבְד֔וֹ בְּכׇל־לְבַבְכֶ֖ם וּבְכׇל־נַפְשְׁכֶֽם׃ וְנָתַתִּ֧י מְטַֽר־אַרְצְכֶ֛ם בְּעִתּ֖וֹ יוֹרֶ֣ה וּמַלְק֑וֹשׁ וְאָסַפְתָּ֣ דְגָנֶ֔ךָ וְתִירֹֽשְׁךָ֖ וְיִצְהָרֶֽךָ׃ וְנָתַתִּ֛י עֵ֥שֶׂב בְּשָׂדְךָ֖ לִבְהֶמְתֶּ֑ךָ וְאָכַלְתָּ֖ וְשָׂבָֽעְתָּ׃
If, then, you obey the commandments that I enjoin upon you this day, loving Adonai and serving God with all your heart and soul, I will grant the rain for your land in season, the early rain and the late. You shall gather in your new grain and wine and oil — I will also provide grass in the fields for your cattle — and thus you shall eat your fill.
“One should not say: ‘Behold, I will study in order to become rich,’ or ‘in order to be called “Rabbi,”’ or ‘in order to receive a reward.’ Instead, one should do everything out of love, and the honor [some manuscripts read: “the reward”] will come in the end.” (Rashi on Deut. 11:13)
