(1) All of the commandments in the Torah: whether they be the positive commandments, or the negative commandments; if a person transgressed any of them, whether he did so intentionally, whether he did so unintentionally, when he repents and returns from his sin - he is obligated to confess before God, blessed be He, as it says (Numbers 5:6-7), When a man or a women does any of the sins of man...and he shall confess his sin that he committed... - this refers to a verbal confession. And confession, that is a positive commandment. How does he confess? He says, "Please God, I have sinned, I have erred, I have [willfully but unrebelliously] transgressed, I have done such-and-such [specific sins], I am regretful, and ashamed for my actions, and I will never again return to my old ways." This is the essence of the confession, and anyone who wants to lengthen [his confession], this is praiseworthy.
(א) אֵי זוֹ הִיא תְּשׁוּבָה גְּמוּרָה. זֶה שֶׁבָּא לְיָדוֹ דָּבָר שֶׁעָבַר בּוֹ וְאֶפְשָׁר בְּיָדוֹ לַעֲשׂוֹתוֹ וּפֵרַשׁ וְלֹא עָשָׂה מִפְּנֵי הַתְּשׁוּבָה. לֹא מִיִּרְאָה וְלֹא מִכִּשְׁלוֹן כֹּחַ. . . אֲפִלּוּ עָבַר כָּל יָמָיו וְעָשָׂה תְּשׁוּבָה בְּיוֹם מִיתָתוֹ וּמֵת בִּתְשׁוּבָתוֹ כָּל עֲוֹנוֹתָיו נִמְחָלִין
(1) 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. . . . 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...
(ט) אֵין הַתְּשׁוּבָה וְלֹא יוֹם הַכִּפּוּרִים מְכַפְּרִין אֶלָּא עַל עֲבֵרוֹת שֶׁבֵּין אָדָם לַמָּקוֹם. . . אֲבָל עֲבֵרוֹת שֶׁבֵּין אָדָם לַחֲבֵרוֹ כְּגוֹן הַחוֹבֵל אֶת חֲבֵרוֹ אוֹ הַמְקַלֵּל חֲבֵרוֹ אוֹ גּוֹזְלוֹ וְכַיּוֹצֵא בָּהֶן אֵינוֹ נִמְחַל לוֹ לְעוֹלָם עַד שֶׁיִּתֵּן לַחֲבֵרוֹ מַה שֶּׁהוּא חַיָּב לוֹ וִירַצֵּהוּ. אַף עַל פִּי שֶׁהֶחֱזִיר לוֹ מָמוֹן שֶׁהוּא חַיָּב לוֹ צָרִיךְ לְרַצּוֹתוֹ וְלִשְׁאל מִמֶּנּוּ שֶׁיִּמְחל לוֹ. אֲפִלּוּ לֹא הִקְנִיט אֶת חֲבֵרוֹ אֶלָּא בִּדְבָרִים צָרִיךְ לְפַיְּסוֹ וְלִפְגֹּעַ בּוֹ עַד שֶׁיִּמְחל לוֹ.
(י) אָסוּר לָאָדָם לִהְיוֹת אַכְזָרִי וְלֹא יִתְפַּיֵּס אֶלָּא יְהֵא נוֹחַ לִרְצוֹת וְקָשֶׁה לִכְעֹס וּבְשָׁעָה שֶׁמְּבַקֵּשׁ מִמֶּנּוּ הַחוֹטֵא לִמְחל מוֹחֵל בְּלֵב שָׁלֵם וּבְנֶפֶשׁ חֲפֵצָה. וַאֲפִלּוּ הֵצֵר לוֹ וְחָטָא לוֹ הַרְבֵּה לֹא יִקֹּם וְלֹא יִטֹּר.
(9) Teshuva and Yom Kippur only atone for transgression between man and God, . . . But transgressions between man and his fellow, such as hurting his fellow, or cursing his fellow, or stealing from him, etc, those are never forgiven until he gives his fellow what he owes him, and [his fellow] is appeased. Even if he returned the money he owed his [fellow], he must appease him and ask him to forgive him. Even if he only perturbed his fellow verbally, he must make amends and meet with him until he forgives him.
(10) It is forbidden for a person to be cruel and not make amends; instead, a person should get appeased easily and get angry slowly. And at the moment when the sinner asks for forgiveness – forgive with a whole heart and a desirous soul. And even if he pained him and sinned against him many times, he should not take revenge or hold a grudge...
