Top Yom Kippur Sources on Sefaria

(9) One who says, "I will sin, and then repent, I will sin [again], and then repent," will not receive an opportunity to repent; [for one who says] "I will sin, and Yom Kipur will atone," Yom Kippur will not atone. Yom Kippur atones for transgressions between a person and God, but for a transgression against one's neighbor, Yom Kipur cannot atone, until he appeases his neighbor. Thus R. Eleazar ben Azariah expounds the text, "From all your sins before the Lord shall ye be clean": For transgressions between a person and God, Yom Kippur atones, for transgressions against one's neighbor, Yom Kippur cannot atone, until he appeases his neighbor. R. Akiva says, Happy are you, Israel! Before whom are you purified, and who purifies you [of your transgressions]? Your Father Who is in heaven. For it is said, "Then will I sprinkle clean water upon you, and ye shall be clean"; and it is also said, "The ‏ritual bath‎ [lit. Hope] of Israel is the Lord"; even as a ritual bath purifies the unclean, so does the Holy One, Blessed be He, purify Israel.

(9) Neither repentance nor the Day of Atonement atone for any save for sins committed between man and God, for instance, one who ate forbidden food, or had forbidden coition and the like; but sins between man and man, for instance, one injures his neighbor, or curses his neighbor or plunders him, or offends him in like matters, is ever not absolved unless he makes restitution of what he owes and begs the forgiveness of his neighbor. And, although he make restitution of the monetory debt, he is obliged to pacify him and to beg his forgiveness. Even he offended not his neighbor in aught save in words, he is obliged to appease him and implore him till he be forgiven by him. If his neighbor refuses a committee of three friends to forgive him, he should bring to implore and beg of him; if he still refuses he should bring a second, even a third committee, and if he remains obstinate, he may leave him to himself and pass on, for the sin then rests upon him who refuses forgiveness. But if it happened to be his master, he should go and come to him for forgiveness even a thousand times till he does forgive him.¹⁰Ibid. 85b; Baba Kamma, 92a; Yoma, 87b. C.

(1) All commandments of the Torah, whether they be mandatory or prohibitive, if a man violates any one of them, either presumptuously or erroneously, when he will repent himself and turn away from his sinful way, he is obliged to confess before God, blessed is He! even as it is said: "When a man or woman shall commit any sin..… Then they shall confess their sin which they have done (Num. 5.6–7), which is a confession of words. Such confession is a mandatory commandment. How is the verbal confession made? The sinner says thus: "I beseech Thee, O Great Name! I have sinned; I have been obstinate; I have committed profanity against Thee, particularly in doing thus and such. Now, behold! I have repented and am ashamed of my actions; forever will I not relapse into this thing again." This is the elementary form of confession; but whosoever elaborates in confessing and extends this subject is, indeed, praise-worthy. Likewise all those who bring sin-offerings or trespass-offerings, when they offer their sacrifices, whether for their errors or for their spitefulness, find no atonement in their sacrifices, unless they repent, and deliver themselves of a verbal confession, even as it is said: "He shall confess that he hath sinned in that thing" (Lev. 5.5) So, too, are the guilty upon whom the tribunal pronounced either a sentence of death or of stripes, who find no atonement either in their death or in being lashed unless they do repent and make verbal confession. Even he, who injures his friend or causes him damages in money matters, although he makes restitution of what he owes him, finds no atonement, unless he makes verbal confession and repents by obligating himself never to repeat this again, even as is said: "Any sin that man commits" (Num. 5.6).¹Sifra, Lev. 5; Yoma, 36b; Shebu’ot, 13a; Sanhedrin, 43a; Baba Kama, 92b.C.

(3) 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.

(4) On Rosh Hashanah it is inscribed, and on Yom Kippur it is sealed - how many shall pass away and how many shall be born, who shall live and who shall die, who in good time, and who by an untimely death, who by water and who by fire, who by sword and who by wild beast, who by famine and who by thirst, who by earthquake and who by plague, who by strangulation and who by lapidation, who shall have rest and who wander, who shall be at peace and who pursued, who shall be serene and who tormented, who shall become impoverished and who wealthy, who shall be debased, and who exalted. But repentance, prayer and righteousness avert the severity of the decree.

(1) On Yom Kippur, it is forbidden to eat, to drink, to wash, to anoint, and to wear leather shoes and to have sexual relations. The King and the bride may wash their faces, and the newly delivered mother may wear leather shoes: the words of Rabbi Eliezer; and the Sages prohibit this.

(2) Ben Azai says: Run to do an easy commandment as to a difficult one, and flee from sin; since a commandment leads to another commandment, and a sin leads to another sin; since the reward for a commandment is another commandment, and the reward for a sin is another sin.
