It was an accident. Why would I need to be forgiven for that?
A sin offering sounds like something for a person who did wrong on purpose. It is the opposite. The Torah introduces it with the words "if a person sins by mistake." For the same act done on purpose, the Mishnah names a different consequence, karet (being cut off), and no offering.
It was also not for every mistake. The Mishnah lists thirty-six cases that carry karet, such as breaking Shabbat, eating chametz on Pesach, and eating or working on Yom Kippur. The Rambam (Maimonides, who died in 1204) states the rule: someone who by mistake breaks a prohibition of that kind, one that involves an action, must bring a sin offering.
Fine, but it was a mistake. Why owe anything? In his Guide for the Perplexed (his book of philosophy) the Rambam sorts it out. A person who was forced has no sin at all. A person who made a mistake is different: "there is sin in it, for if he had taken more care, the mistake would not have come his way." Then he adds: such a person is not punished at all. He needs atonement, so he brings an offering.
The Ramban (a Torah commentator from Spain, 1200s) gives a different reason. He looks at what a sin does to you. Every sin, he writes, leaves something ugly in the soul, a flaw, even when you did not mean it. The offering is there so the soul can come close again to the God who gave it.
So there are two answers. One: you could have been more careful. Two: even if you did not mean it, something in you was damaged and has to be repaired. Think of dropping a friend's phone. You did not mean to. You still deal with it.
One more detail. A sin offering could never be given as a gift, which is why the line after this paragraph begins with "if." And the Torah says it comes when "his sin becomes known to him." For that reason, the Mishnah Berurah records, one authority held the line should not be said at all.
Vayikra 4:27-28,Mishnah Keritot 1:1-2,Rambam, Laws of Unintentional Sins 1:1,Rambam, Guide for the Perplexed 3:41 (Ibn Tibbon's Hebrew),Ramban on Vayikra 4:2,Tur, Orach Chaim 1,Mishnah Berurah 1:18I thought arguing was the whole point. Why pick the chapter with no arguments?
Most of the Mishnah is rabbis disagreeing, and you may have been taught that the arguing is what makes Torah study great. So why choose a chapter without any?
Start with the Rambam (Maimonides, who died in 1204). In Mishneh Torah (his code of law) he writes that things received by tradition are never disputed. If you find a dispute about something, he says, you can be sure it was not a tradition from Moshe. Put that next to what the Ra'ah says about this chapter: no dispute, "a clear Mishnah from Moshe at Sinai."
The Rambam also tells how disputes grew. While the High Court sat in Jerusalem, "there was no dispute in Israel." A question went up from court to court until it was settled, by tradition or by a vote. When the High Court ended, "dispute multiplied in Israel: one says impure and gives his reason, one says pure and gives his reason." In that telling, dispute is a sign that something was lost.
That is not the only voice. Pirkei Avot (the part of the Mishnah that collects the early rabbis' sayings on how to live) says a dispute for the sake of Heaven will last, and its example is Hillel and Shammai. The Gemara (the rabbis' discussions built on the Mishnah) reports a voice from heaven about their two schools: "These and those are the words of the living God."
The Kaf HaChaim (a major work of Jewish law by Rabbi Yaakov Chaim Sofer, who died in Jerusalem in 1939) points out that "no dispute" means none is mentioned inside the chapter. Some of its rulings are disputed elsewhere. The last paragraph of the chapter says the Pesach offering is eaten only until midnight. The Gemara says that line is Rabbi Elazar ben Azaryah's view. Rabbi Akiva disagreed.
So once a day you get Torah with no argument attached. After this chapter come Rabbi Yishmael's thirteen rules for working out law from the Torah's words. The Rambam says law worked out with rules like those is where the Sages could disagree, and then they voted.
Beit Yosef, Orach Chaim 50, quoting the Ra'ah,Rambam, Laws of Rebels 1:2-4,Pirkei Avot 5:17,Eruvin 13b,Kaf HaChaim, Orach Chaim 50:1,Zevachim 57b; Berakhot 9aIf the people in charge got it wrong and I followed them, is that on me?
The second paragraph mentions "bulls that are burned." One kind is for a strange case: the whole community sins by mistake, because something was "hidden from the eyes of the congregation." Rashi (the classic Torah commentator, France, 1000s) explains. The High Court (the Sanhedrin) ruled that a forbidden thing was allowed, and the people acted on its word.
So who brings the offering? The Rambam (Maimonides, who died in 1204) writes that the court is liable, for the ruling itself, even if no judge did the act. The bulls, he rules, come from the community: one from each tribe. The people who did the act bring no offering of their own, "because they relied on the court."
That can sound as if following the court always exempts you. The Mishnah in Horayot (its section on mistaken rulings) sets a limit. Say a judge knew the court was wrong, or a student able to rule, and acted on the ruling anyway. He is liable, "because he did not rely on the court."
The Gemara (the rabbis' discussions built on the Mishnah) pushes back. A scholar like that did it on purpose, not by mistake. The answer: he knew it was forbidden, and made a different mistake. In the Rambam's words, he thought it is a mitzvah to listen to the court "even though they are mistaken."
An ordinary person in the same spot is exempt, the Rambam adds: his knowledge of what is forbidden is not certain.
Even that exemption has limits. In the Gemara, Shmuel (one of its early rabbis) is quoted as saying this Mishnah is one rabbi's view, and that the other Sages held an individual who acted on the court's ruling is liable. The Rambam rules that if only a minority followed the court, each one brings his own sin offering. The same goes if another of his conditions is missing, such as a full High Court of seventy-one.
A note from us: this is one narrow case, the High Court's mistaken ruling and who brings an offering. These sources give no general rule about following orders.
