(Devarim 32:40) "For I shall raise My hand (in oath) to heaven": When the Holy One Blessed be He created man, He did so by pronouncement (ma'amar) and not by oath. And who caused Him to swear? Those lacking in faith. As it is written (Psalms 106:26-27) "And He lifted up His hand to cast them down in the desert and to cast down their seed among the nations."
(see Bamidbar 14:21). "I said: I live forever": For not as the measure of the Holy One Blessed be He is the measure of man. The measure of man: A noble enters his province (to exact vengeance). If he can exact from the living, he does so; if not, he does not. But not so with Him who spoke and caused the world to come into being. If He does not exact it from the living, He exacts it from the dead. If He does not exact it in this world, He exacts it in the world to come.
(דברים לב מ) כִּי אֶשָּׂא אֶל שָׁמַיִם יָדִי, כְּשֶׁבָּרָא הַקָּדוֹשׁ בָּרוּךְ הוּא אֶת הָעוֹלָם לֹא בְרָאוֹ אֶלָּא בְּמַאֲמָר וְלֹא בְרָאוֹ אֶלָּא בִּשְׁבוּעָה, וּמִי גָּרַם לוֹ לִשָּׁבַע? מְחֻסְּרֵי אֲמָנָה הֵם גָּרְמוּ לוֹ לִשָּׁבַע, שֶׁנֶּאֱמַר (תהלים קו כו): ״וַיִּשָּׂא יָדוֹ לָהֶם לְהַפִּיל אוֹתָם בַּמִּדְבָּר״ (יחזקאל לו ז): ״אֲנִי נָשָׂאתִי אֶת יָדִי אֶל הַגּוֹיִם״ וְגוֹ׳.

וְאָמַרְתִּי חַי אָנֹכִי לְעֹלָם, שֶׁלֹּא כְּמִדַּת בָּשָׂר וָדָם מִדַּת הַקָּדוֹשׁ בָּרוּךְ הוּא: מִדַּת בָּשָׂר וָדָם הַפִּיטְקִי נִכְנָס לְתוֹךְ אַפַּרְכְיָא שֶׁלּוֹ, אִם יָכוֹל לִפָּרַע מִן הַפִּיטְקִי שֶׁלּוֹ הוּא נִפְרָע, וְאִם לָאו אֵין יָכוֹל לִיפָּרַע. אֲבָל מִי שֶׁאָמַר וְהָיָה הָעוֹלָם אֵינוֹ כֵן, אִם אֵינוֹ נִפְרָע מִן הַחַיִּים נִפְרָע מִן הַמֵּתִים, אִם אֵינוֹ נִפְרָע בָּעוֹלָם הַזֶּה נִפְרָע לָעוֹלָם הַבָּא.
