אֱלֹהַי. עַד שֶׁלֹּא נוֹצַֽרְתִּי אֵינִי כְדַאי, וְעַכְשָׁו שֶׁנּוֹצַֽרְתִּי כְּאִלּוּ לֹא נוֹצַֽרְתִּי. עָפָר אֲנִי בְּחַיָּי. קַל וָחֹֽמֶר בְּמִיתָתִי. הֲרֵי אֲנִי לְפָנֶֽיךָ כִּכְלִי מָלֵא בוּשָׁה וּכְלִמָּה.
God, before I was formed, I was unworthy [to be created]. And now that I have been formed, it is as if I had not been formed. I am like dust while I live, how much more so when I am dead. Here I am before You like a vessel filled with shame.
רָבָא בָּתַר צְלוֹתֵיהּ אָמַר הָכִי: ״אֱלֹהַי, עַד שֶׁלֹּא נוֹצַרְתִּי אֵינִי כְּדַאי, וְעַכְשָׁיו שֶׁנּוֹצַרְתִּי כְּאִלּוּ לֹא נוֹצַרְתִּי. עָפָר אֲנִי בְּחַיַּי, קַל וָחוֹמֶר בְּמִיתָתִי, הֲרֵי אֲנִי לְפָנֶיךָ כִּכְלִי מָלֵא בּוּשָׁה וּכְלִימָּה. יְהִי רָצוֹן מִלְּפָנֶיךָ ה׳ אֱלֹהַי, שֶׁלֹּא אֶחֱטָא עוֹד, וּמַה שֶּׁחָטָאתִי לְפָנֶיךָ מָרֵק בְּרַחֲמֶיךָ הָרַבִּים, אֲבָל לֹא עַל יְדֵי יִסּוּרִין וָחֳלָאִים רָעִים״. וְהַיְינוּ וִידּוּי דְרַב הַמְנוּנָא זוּטֵי בְּיוֹמָא דְכִפּוּרֵי.
After his prayer, Rava said the following:
My God, before I was created I was worthless,
and now that I have been created it is as if I had not been created, I am no more significant.
I am dust in life, all the more so in my death.
I am before You as a vessel filled with shame and humiliation.
Therefore, may it be Your will, Lord my God, that I will sin no more,
and that those transgressions that I have committed,
cleanse in Your abundant mercy;
but may this cleansing not be by means of suffering and serious illness, but rather in a manner I will be able to easily endure.
And this is the confession of Rav Hamnuna Zuti on Yom Kippur.
וּמַה הִיא הַתְּשׁוּבָה. הוּא שֶׁיַּעֲזֹב הַחוֹטֵא חֶטְאוֹ וִיסִירוֹ מִמַּחֲשַׁבְתּוֹ וְיִגְמֹר בְּלִבּוֹ שֶׁלֹּא יַעֲשֵׂהוּ עוֹד שֶׁנֶּאֱמַר (ישעיה נה ז) "יַעֲזֹב רָשָׁע דַּרְכּוֹ" וְגוֹ'. וְכֵן יִתְנַחֵם עַל שֶׁעָבַר שֶׁנֶּאֱמַר (ירמיה לא יט) "כִּי אַחֲרֵי שׁוּבִי נִחַמְתִּי". וְיָעִיד עָלָיו יוֹדֵעַ תַּעֲלוּמוֹת שֶׁלֹּא יָשׁוּב לְזֶה הַחֵטְא לְעוֹלָם שֶׁנֶּאֱמַר (הושע יד ד) "וְלֹא נֹאמַר עוֹד אֱלֹהֵינוּ לְמַעֲשֵׂה יָדֵינוּ" וְגוֹ'. וְצָרִיךְ לְהִתְוַדּוֹת בִּשְׂפָתָיו וְלוֹמַר עִנְיָנוֹת אֵלּוּ שֶׁגָּמַר בְּלִבּוֹ:
What is repentance? The sinner shall cease sinning, and remove sin from his thoughts, and wholeheartedly conclude not to revert back to it, even as it is said: "Let the wicked forsake his way" (Is. 55.7); so, too, shall he be remorseful on what was past, even as it is said: "Surely after that I was turned, I repented" (Jer. 31. 19). In addition thereto he should take to witness Him Who knoweth all secrets that forever he will not turn to repeat that sin again, according to what it is said: "Say unto Him.… neither will we call any more the work of our hands our gods" (Hos. 14.3–4). It is, moreover, essential that his confession shall be by spoken words of his lips, and all that which he concluded in his heart shall be formed in speech.2Yoma, 57b; Shabbat, 121. G.
כָּל הַמִּתְוַדֶּה בִּדְבָרִים וְלֹא גָּמַר בְּלִבּוֹ לַעֲזֹב הֲרֵי זֶה דּוֹמֶה לְטוֹבֵל וְשֶׁרֶץ בְּיָדוֹ שֶׁאֵין הַטְּבִילָה מוֹעֶלֶת לוֹ עַד שֶׁיַּשְׁלִיךְ הַשֶּׁרֶץ. וְכֵן הוּא אוֹמֵר וּמוֹדֶה וְעֹזֵב יְרֻחָם. וְצָרִיךְ לִפְרֹט אֶת הַחֵטְא שֶׁנֶּאֱמַר (שמות לב לא) "אָנָּא חָטָא הָעָם הַזֶּה חֲטָאָה גְדלָה וַיַּעֲשׂוּ לָהֶם אֱלֹהֵי זָהָב":
He who confesses by speech but has not his heart's consent to abandon his erstwhile conduct, behold him, he is like one taking an immersion of purification and in his grasp is an impure creeping thing, when he knows the immersion to be of no value till he cast away the impure creeping thing. Even so it is advised to do, saying: "But whoso confesseth and forsaketh them shall shall obtain mercy" (Pro. 28. 13). In confessing to God, it is obligatory to name the sin, even as it is said: "Oh, this people have sinned a great sin, and have made them a god of gold" (Ex. 32.31).3Ta’anit, 16a; Yoma, 86b. C.
