Chapter 2 of 10 in Repentance — 11 halachot
Halacha 1א׳
אֵי זוֹ הִיא תְּשׁוּבָה גְּמוּרָה. זֶה שֶׁבָּא לְיָדוֹ דָּבָר שֶׁעָבַר בּוֹ וְאֶפְשָׁר בְּיָדוֹ לַעֲשׂוֹתוֹ וּפֵרַשׁ וְלֹא עָשָׂה מִפְּנֵי הַתְּשׁוּבָה. לֹא מִיִּרְאָה וְלֹא מִכִּשְׁלוֹן כֹּחַ. כֵּיצַד. הֲרֵי שֶׁבָּא עַל אִשָּׁה בַּעֲבֵרָה וּלְאַחַר זְמַן נִתְיַחֵד עִמָּהּ וְהוּא עוֹמֵד בְּאַהֲבָתוֹ בָּהּ וּבְכֹחַ גּוּפוֹ וּבַמְּדִינָה שֶׁעָבַר בָּהּ וּפָרַשׁ וְלֹא עָבַר זֶהוּ בַּעַל תְּשׁוּבָה גְּמוּרָה. הוּא שֶׁשְּׁלֹמֹה אָמַר (קהלת יב א) "וּזְכֹר אֶת בּוֹרְאֶיךָ בִּימֵי בְּחוּרֹתֶיךָ". וְאִם לֹא שָׁב אֶלָּא בִּימֵי זִקְנוּתוֹ וּבְעֵת שֶׁאִי אֶפְשָׁר לוֹ לַעֲשׂוֹת מַה שֶּׁהָיָה עוֹשֶׂה אַף עַל פִּי שֶׁאֵינָהּ תְּשׁוּבָה מְעֻלָּה מוֹעֶלֶת הִיא לוֹ וּבַעַל תְּשׁוּבָה הוּא. אֲפִלּוּ עָבַר כָּל יָמָיו וְעָשָׂה תְּשׁוּבָה בְּיוֹם מִיתָתוֹ וּמֵת בִּתְשׁוּבָתוֹ כָּל עֲוֹנוֹתָיו נִמְחָלִין שֶׁנֶּאֱמַר (קהלת יב ב) "עַד אֲשֶׁר לֹא תֶחְשַׁךְ הַשֶּׁמֶשׁ וְהָאוֹר וְהַיָּרֵחַ וְהַכּוֹכָבִים וְשָׁבוּ הֶעָבִים אַחַר הַגֶּשֶׁם" שֶׁהוּא יוֹם הַמִּיתָה. מִכְּלָל שֶׁאִם זָכַר בּוֹרְאוֹ וְשָׁב קֹדֶם שֶׁיָּמוּת נִסְלַח לוֹ:
What is complete teshuvah? When a person has the opportunity to commit the same sin, and he possess the ability to do it, but he separates and does not do it because of teshuvah and not out of fear or lack of strength. What is an example? A person who had illicit sex with a woman, and after some time he is alone with her, and he still loves her and possesses his physical power and is in the same country where he committed the sin, but he separates and does not sin – that person is a complete ba’al teshuvah, about whom [King] Solomon said, Remember your Creator in the days of your youth (Ecclesiastes 12:1). And if a person only does teshuvah in the days of old age, when it is not possible to do what he once did, even though this is not the highest teshuvah, it is effective and that person is a ba’al teshuvah. Even if a person sinned all his days and did teshuvah on the day of his death and died in his teshuvah, all his sins are forgiven, as it says, Before the sun is darkened, and the light of the moon and the stars, and the clouds return after the rain (Ecclesiastes 12:2), which is the day of death. This implies that if he remembers his Creator and does teshuvah before he dies, he is forgiven.
Halacha 2ב׳
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 teshuvah? It is when a person abandons the sin that he sinned and removes it from his thoughts and commits in his heart that he will not do it again, as it says, The wicked should abandon his path etc. (Isaiah 55:7). And also that he regrets sinning, as it says, After I returned I regretted (Jeremiah 31:19). And the One Who Knows Hidden Things testifies about him that he will never return to this sin, as it says, And we will no longer call the work of our hands “god” etc. (Hosea 14:4). And he must confess verbally and say these things that he has committed in his heart.
Halacha 3ג׳
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 (משלי כח יג). וְצָרִיךְ לִפְרֹט אֶת הַחֵטְא שֶׁנֶּאֱמַר (שמות לב לא) "אָנָּא חָטָא הָעָם הַזֶּה חֲטָאָה גְדלָה וַיַּעֲשׂוּ לָהֶם אֱלֹהֵי זָהָב":
Anyone who confesses verbally and does not commit in his heart to abandon [sin], this is like a person who immerses [in a purity pool] while holding an unclean creature in his hand, so that the bath is not effective until he sends away the unclean creature, and so it says, One who admits and abandons is given mercy (Proverbs 28:13). And he must specify the sin, as it says, This nation has sinned a great sin and made a golden god for themselves (Exodus 32:31).
