העדתי בכם היום את השמים ואת הארץ. שֶׁהֵם קַיָּמִים לְעוֹלָם, וְכַאֲשֶׁר תִּקְרֶה אֶתְכֶם הָרָעָה יִהְיוּ עֵדִים שֶׁאֲנִי הִתְרֵיתִי בָכֶם בְּכָל זֹאת; דָּבָר אַחֵר — העדתי בכם היום את השמים וגו', אָמַר לָהֶם הַקָּדוֹשׁ בָּרוּךְ הוּא לְיִשְׂרָאֵל, הִסְתַּכְּלוּ בַשָּׁמַיִם שֶׁבָּרָאתִי לְשַׁמֵּשׁ אֶתְכֶם, שֶׁמָּא שִׁנּוּ אֶת מִדָּתָם? שֶׁמָּא לֹא עָלָה גַּלְגַּל חַמָּה מִן הַמִּזְרָח וְהֵאִיר לְכָל הָעוֹלָם כָּעִנְיָן שֶׁנֶּאֱמַר (קהלת א') "וְזָרַח הַשֶּׁמֶשׁ וּבָא הַשָּׁמֶשׁ"? הִסְתַּכְּלוּ בָאָרֶץ שֶׁבָּרָאתִי לְשַׁמֵּשׁ אֶתְכֶם, שֶׁמָּא שִׁנְּתָה מִדָּתָהּ? שֶׁמָּא זְרַעְתֶּם אוֹתָהּ וְלֹא צָמְחָה אוֹ שֶׁמָּא זְרַעְתֶּם חִטִּים וְהֶעֶלְתָה שְׂעוֹרִים? וּמָה אֵלּוּ שֶׁנַּעֲשׂוּ לֹא לְשָׂכָר וְלֹא לְהֶפְסֵד, אִם זוֹכִין אֵין מְקַבְּלִין שָׂכָר וְאִם חוֹטְאִין אֵין מְקַבְּלִין פֻּרְעָנוּת, לֹא שִׁנּוּ אֶת מִדָּתָם, אַתֶּם שֶׁאִם זְכִיתֶם תְּקַבְּלוּ שָׂכָר וְאִם חֲטָאתֶם תְּקַבְּלוּ פֻּרְעָנוּת, עַל אַחַת כַּמָּה וְכַמָּה (ספרי דברים ל"ב): העדתי בכם היום את השמים ואת הארץ I CALL AS WITNESSES AGAINST YOU THE HEAVEN AND THE EARTH, which exist for ever, and when evil will befall you they will be witnesses that I have warned you regarding all this (cf. Targum Jonathan on). Another explanation of העדתי בכם את השמים וגו׳ I CALL THE HEAVEN [AND THE EARTH] AS WITNESSES AGAINST YOU: The Holy One, blessed be He, said to Israel, “Look at the heavens which I have created to be at your service; have they perhaps ever changed their character? Has the orb of the sun perhaps ever failed to rise in the East and to give light to the whole world, just as is stated, (Ecclesiastes 1:4—5) “And the sun riseth, and the sun goeth down [and hasteth to its place where it arises]”?! Look at the earth which I have created to be at your service! Has it perhaps ever changed its character? Have you perhaps sown it and it did not bring forth, or have you sown wheat and it brought forth barley?! Now how is it with these that have been made neither with the end in view that they should receive a reward nor that they should suffer a loss — for if they act meritoriously (if they follow the natural laws by which they are governed) they receive no reward and if they were to fail they would receive no punishment? They have never changed their character! You, who if you act meritoriously do receive a reward and if you sin do receive punishment, how much the more so should you obey the commands of your Maker! (Sifrei Devarim 306:1).
ובחרת בחיים. אֲנִי מוֹרֶה לָכֶם שֶׁתִּבְחֲרוּ בְּחֵלֶק הַחַיִּים, כְּאָדָם הָאוֹמֵר לִבְנוֹ, בְּחַר לְךָ חֵלֶק יָפֶה בְנַחֲלָתִי, וּמַעֲמִידוֹ עַל חֵלֶק הַיָּפֶה וְאוֹמֵר לוֹ אֶת זֶה בְּרֹר לְךָ, וְעַל זֶה נֶאֱמַר (תהילים ט"ז) "ה' מְנָת חֶלְקִי וְכוֹסִי אַתָּה תּוֹמִיךְ גּוֹרָלִי" — הִנַּחְתָּ יָדִי עַל גּוֹרָל הַטּוֹב לוֹמַר אֶת זֶה קַח לְךָ: ובחרת בחיים THEREFORE CHOOSE THE LIFE — I show you these (“I set life and death before thee) in order that you may choose the portion of life. It is like a man who says to his son, “Choose for yourself a good portion of my real estate”, and sets him in the best portion saying to him, “Choose this!” And concerning this it states, (Psalms 16:5) “The Lord is the portion of my inheritance and my cup, אתה תומיך גורלי”, i.e. “You place my hand on the good lot, saying, ‘Choose this!'”
