אמרו שנים עשר אלף זוגים תלמידים היו לו לרבי עקיבא מגבת עד אנטיפרס וכולן מתו בפרק אחד מפני שלא נהגו כבוד זה לזה והיה העולם שמם עד שבא ר"ע אצל רבותינו שבדרום ושנאה להם ר"מ ור' יהודה ור' יוסי ורבי שמעון ורבי אלעזר בן שמוע והם הם העמידו תורה אותה שעה תנא כולם מתו מפסח ועד עצרת אמר רב חמא בר אבא ואיתימא ר' חייא בר אבין כולם מתו מיתה רעה מאי היא א"ר נחמן אסכרה
It was said, That Rabbi Akiva had twelve thousand pairs of disciples, from Gabbat to Antifaras; and they all died at the same time because they did not treat each other with respect. The world remained desolate until Rabbi Akiva came to our Masters in the South and taught the Torah to them. and it was they who revived the Torah at that time. These were Rabbi Meir, Rabbi Judah, Rabbi Yossi, Rabbi Shimon and Rabbi Eleazar ben Shammua; And it was they who revived the Torah at that time. A Tanna taught: All of them died between Passover and Pentecost. Rabbi Hama bar Abba or, it might be said, Rabbi Chiyya bar Abin said: All of them died a cruel death. What was it? — Rabbi Nahman replied: Croup.
Teshuvah Chapter 1
Halacha 1
If a person transgresses any of the mitzvot of the Torah, whether a positive command or a negative command - whether willingly or inadvertently - when he repents, and returns from his sin, he must confess before God, blessed be, He as [Numbers 5:6-7] states: "If a man or a woman commit any of the sins of man... they must confess the sin that they committed."
This refers to a verbal confession. This confession is a positive command.
How does one confess: He states: "I implore You, God, I sinned, I transgressed, I committed iniquity before You by doing the following. Behold, I regret and am embarrassed for my deeds. I promise never to repeat this act again."
These are the essential elements of the confessional prayer. Whoever
confesses profusely and elaborates on these matters is worthy of praise.
Those who bring sin offerings or guilt offerings must also [confess their sins] when they bring their sacrifices for their inadvertent or willful transgressions. Their sacrifices will not atone for their sins until they repent and make a verbal confession as [Leviticus 5:5] states: "He shall confess the sin he has committed upon it."
Similarly, those obligated to be executed or lashed by the court do not attain atonement through their death or lashing unless they repent and confess. Similarly, someone who injures a colleague or damages his property, does not attain atonement, even though he pays him what he owes until he confesses and makes a commitment
never to do such a thing again as implied by the phrase [Numbers, loc. cit..], "any of the sins of man."
Halacha 2
Since the goat sent [to Azazel] atones for all of Israel, the High Priest confesses upon it as a spokesman for all of Israel as [Leviticus 16:21] states: "He shall confess upon it all the sins of the children of Israel."
The goat sent to Azazel atones for all the transgressions in the Torah, the severe and the lighter [sins]; those violated intentionally and those transgressed inadvertently; those which [the transgressor] became conscious of and those which he was not conscious of. All are atoned for by the goat sent [to Azazel].
This applies only if one repents. If one does not repent, the goat only atones for the light [sins].
Which are light sins and which are severe ones? The severe sins are those for which one is liable for execution by the court or karet. False and unnecessary oaths are also considered severe sins even though they are not [punished by] karet. [The violation of] the other prohibitions and [the failure to perform] positive commandments that are not punishable by karet are considered light [sins].
Halacha 3
At present, when the Temple does not exist and there is no altar of atonement, there remains nothing else aside from Teshuvah.
Teshuvah atones for all sins. Even a person who was wicked his whole life and repented in his final moments will not be reminded of any aspect of his wickedness as [Ezekiel 33:12] states "the wickedness of the evil one will not cause him to stumble on the day he repents his wickedness."
The essence of Yom Kippur atones for those who repent as [Leviticus 16:30] states: "This day will atone for you."
Halacha 4
Even though Teshuvah atones for all [sins] and the essence of Yom Kippur brings atonement, [there are different levels of sin and hence, differences in the degree of atonement.] There are sins that can be atoned for immediately and other sins which can only be atoned for over the course of time. What is implied?
If a person violates a positive command which is not punishable by karet and repents, he will not leave that place before he is forgiven. Concerning these sins, [Jeremiah 3:22] states: "Return, faithless children! I will heal your rebellious acts."
If a person violates a prohibition that is not punishable by karet or execution by the court and repents, Teshuvah has a tentative effect and Yom Kippur brings atonement as [Leviticus, loc. cit. states "This day will atone for you."
If a person violates [sins punishable by] karet or execution by the court and repents, Teshuvah and Yom Kippur have a tentative effect and the sufferings which come upon him complete the atonement. He will never achieve complete atonement until he endures suffering for concerning these [sins, Psalms 89:33] states: "I will punish their transgression with a rod."
When does the above apply: When the desecration of God's name is not involved in the transgression. However, a person who desecrated God's name, even though he repented, Yom Kippur arrived while he continued his repentance, and he experienced suffering, will not be granted complete atonement until he dies. The three: repentance, Yom Kippur, and suffering have a tentative effect and death atones as [Isaiah 22:14] states: "It was revealed in my ears [by] the Lord of Hosts, surely this iniquity will not be atoned for until you die."
