"And Jacob said, O God of my father Abraham" (Genesis 32:10). This was not for Esau's sake; rather, it is the one who chooses their ways and acts according to their deeds upon whom I attach My name. Who was nearer to David than Ahaz? Yet He leaves Ahaz aside and says to Hezekiah, "Thus says the LORD, the God of David your father" (II Kings 20:5). Rather, the one who chooses their ways and acts according to their deeds, upon him I attach My name. "I have been made small by all the kindnesses" (Genesis 32:11): Rabbi Abba bar Kahana said, it means "I am not worthy": "I have been made small by all the kindnesses." Rabbi Levi said, it means "I am worthy": "I have been made small by all the kindnesses" (this is written in remez 32).
God of My Father Abraham and I Have Been Made Small by All Your Kindnesses
Yalkut Shimoni on Torah 131:4
וַיֹּאמֶר [יַעֲקֹב] אֱלֹהֵי אָבִי אַבְרָהָם, הָא לְעֵשָׂו לֹא אֶלָּא הַבּוֹחֵר בְּדַרְכֵיהֶם וְהָעוֹשֶׂה כְּמַעֲשֵׂיהֶם אֲנִי מִתְקַיֵּם עֲלֵיהֶם מִי הָיָה קָרוֹב לְדָוִד, לֹא אָחָז, הוּא מַנִּיחַ לְאָחָז וְאָמַר לְחִזְקִיָּהוּ "כֹּה אָמַר ה' אֱלֹהֵי דָּוִד אָבִיךָ", אֶלָּא הַבּוֹחֵר בְּדַרְכֵיהֶם וְהָעוֹשֶׂה כְּמַעֲשֵׂיהֶם אֲנִי מִתְקַיֵּם עֲלֵיהֶם. (בראשית לב יא) קָטֹנְתִּי מִכֹּל הַחֲסָדִים, רַבִּי אַבָּא בַּר כַּהֲנָא אָמַר, אֵינִי כְּדַאי קָטֹנְתִּי מִכֹּל הַחֲסָדִים. רַבִּי לֵוִי אָמַר, כְּדַאי אֲנִי קָטֹנְתִּי מִכֹּל הַחֲסָדִים (כָּתוּב בְּרֶמֶז ל"ב).
