Leviticus 23:27-32

(27) Mark, the tenth day of this seventh month is the Day of Atonement. It shall be a sacred occasion for you: you shall practice self-denial, and you shall bring an offering by fire to יהוה; (28) you shall do no work throughout that day. For it is a Day of Atonement, on which expiation is made on your behalf before your God יהוה. (29) Indeed, any person who does not practice self-denial throughout that day shall be cut off from kin; (30) and whoever does any work throughout that day, I will cause that person to perish from among the people. (31) Do no work whatever; it is a law for all time, throughout the ages in all your settlements. (32) It shall be a sabbath of complete rest for you, and you shall practice self-denial; on the ninth day of the month at evening, from evening to evening, you shall observe this your sabbath.

Mishnah Yoma 8:9

(9) With regard to one who says: I will sin and then I will repent, I will sin and I will repent, Heaven does not provide him the opportunity to repent, and he will remain a sinner all his days. With regard to one who says: I will sin and Yom Kippur will atone for my sins, Yom Kippur does not atone for his sins. Furthermore, for transgressions between a person and God, Yom Kippur atones; however, for transgressions between a person and another, Yom Kippur does not atone until he appeases the other person. Similarly, Rabbi Elazar ben Azarya taught that point from the verse: “From all your sins you shall be cleansed before the Lord” (Leviticus 16:30). For transgressions between a person and God, Yom Kippur atones; however, for transgressions between a person and another, Yom Kippur does not atone until he appeases the other person.

יומא פ״ז א:י״ג-י״ד

(וְאָמַר) רַבִּי יוֹסֵי בַּר חֲנִינָא: כׇּל הַמְבַקֵּשׁ מָטוּ מֵחֲבֵירוֹ, אַל יְבַקֵּשׁ מִמֶּנּוּ יוֹתֵר מִשָּׁלֹשׁ פְּעָמִים, שֶׁנֶּאֱמַר: ״אָנָּא שָׂא נָא וְעַתָּה שָׂא נָא״. וְאִם מֵת — מֵבִיא עֲשָׂרָה בְּנֵי אָדָם וּמַעֲמִידָן עַל קִבְרוֹ, וְאוֹמֵר: חָטָאתִי לַה׳ אֱלֹהֵי יִשְׂרָאֵל וְלִפְלוֹנִי שֶׁחָבַלְתִּי בּוֹ. רַבִּי יִרְמְיָה הֲוָה לֵיהּ מִילְּתָא לְרַבִּי אַבָּא בַּהֲדֵיהּ, אֲזַל אִיתִּיב אַדַּשָּׁא דְּרַבִּי אַבָּא בַּהֲדֵי דְּשָׁדְיָא אַמְּתֵיהּ מַיָּא, מְטָא זַרְזִיפֵי דְמַיָּא אַרֵישָׁא. אָמַר: עֲשָׂאוּנִי כְּאַשְׁפָּה. קְרָא אַנַּפְשֵׁיהּ: ״מֵאַשְׁפּוֹת יָרִים אֶבְיוֹן״. שְׁמַע רַבִּי אַבָּא וּנְפֵיק לְאַפֵּיהּ, אֲמַר לֵיהּ: הַשְׁתָּא צְרִיכְנָא לְמִיפַּק אַדַּעְתָּךְ, דִּכְתִיב: ״לֵךְ הִתְרַפֵּס וּרְהַב רֵעֶיךָ״.

Yoma 87a:13-14

Rabbi Yosei bar Ḥanina said: Anyone who asks forgiveness of his friend should not ask more than three times, as it is stated: “Please, please forgive the transgression of your brothers and their sin, for they did evil to you. And now, please forgive” (Genesis 50:17). The verse uses the word please three times, which shows that one need not ask more than three times, after which the insulted friend must be appeased and forgive. And if the insulted friend dies before he can be appeased, one brings ten people, and stands them at the grave of the insulted friend, and says in front of them: I have sinned against the Lord, the God of Israel, and against so-and-so whom I wounded. The Gemara relates that Rabbi Yirmeya insulted Rabbi Abba, causing the latter to have a complaint against him. Rabbi Yirmeya went and sat at the threshold of Rabbi Abba’s house to beg him for forgiveness. When Rabbi Abba’s maid poured out the dirty water from the house, the stream of water landed on Rabbi Yirmeya’s head. He said about himself: They have made me into a trash heap, as they are pouring dirty water on me. He recited this verse about himself: “Who lifts up the needy out of the trash heap” (Psalms 113:7). Rabbi Abba heard what happened and went out to greet him. Rabbi Abba said to him: Now I must go out to appease you for this insult, as it is written: “Go, humble yourself [hitrapes] and urge your neighbor” (Proverbs 6:3).
