Matthew 5:24
21 “You have heard that it was said to an older generation, ‘Do not murder,’ and ‘whoever murders will be subjected to judgment.’ 22 But I say to you that anyone who is angry with a brother will be subjected to judgment. And whoever insults a brother will be brought before the council, and whoever says ‘Fool’ will be sent to fiery hell. 23 So then, if you bring your gift to the altar and there you remember that your brother has something against you, 24 leave your gift there in front of the altar. First go and be reconciled to your brother and then come and present your gift. 25 Reach agreement quickly with your accuser while on the way to court, or he may hand you over to the judge, and the judge hand you over to the warden, and you will be thrown into prison. 26 I tell you the truth, you will never get out of there until you have paid the last penny!
Mishnah Yoma 8:9
MishnahWith 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. In conclusion, Rabbi Akiva said: How fortunate are you, Israel; before Whom are you purified, and Who purifies you? It is your Father in Heaven, as it is stated: “And I will sprinkle purifying water upon you, and you shall be purified” (Ezekiel 36:25). And it says: “The ritual bath of Israel is God” (Jeremiah 17:13). Just as a ritual bath purifies the impure, so too, the Holy One, Blessed be He, purifies Israel.
Notes and References
"... Statements in the Gospels about fasting refer to weekly fasts and to the ascetic lifestyle of overachievers like John the Baptist. Regarding the temple cult we can infer from the so-called 'cleansing' of the temple that Jesus seems to have regarded the temple primarily as a place of prayer. But passages such as Matthew 5:24 provide evidence that Jesus regarded also the purification and sin offerings in the temple as part of his conception of Judaism ... According to Tidwell, the hapaxlegomenon and lectio difficilior of Didache 14:1 is a pleonastic Semitism imitating one of the names of Yom Kippur ... the major topic of Didache 14:1 is therefore best understood as equivalent of 'Sabbath of Sabbaths', i.e. Yom Kippur. The major topic of Didache 14, confession and reconciliation, matches the statement in Mishnah Yoma 8:9 that 'Yom Kippur atones for transgressions between a man and his fellow man only after he has placated the fellow man' ..."
