About this episode
A kohen gadol is obligated to bring a special bull offering only if he issues an erroneous halachic ruling unintentionally and then personally acts upon that ruling. A braita derives this from the verse "לְאַשְׁמַת הָעָם" ("for the guilt of the nation"), which compares the kohen gadol's actions to those of the community when they bring a communal sin offering. This drasha is necessary because one might have assumed that the kohen gadol's obligation could be learned directly from the communal offering paradigm, given their similarities. However, since the kohen gadol could also be compared to the nasi (king), who brings a sacrifice without issuing a mistaken ruling, the comparison is not straightforward. The drasha clarifies that the kohen gadol's case aligns specifically with the communal model. Another drasha teaches that if the kohen gadol issues an erroneous ruling but the people act on it while he himself does not, no special bull offering is brought. The offering is only required when the kohen gadol personally commits the sin. The Mishna rules that if the kohen gadol and the court issue rulings simultaneously but on different matters—where the community follows the court and the kohen gadol follows his own ruling—he must bring an individual sacrifice. However, if he rules with the court on the same issue and acts together with the community, he is atoned through the communal bull offering, not the unique one designated for the kohen gadol. A braita attempts to derive this latter case by comparing the kohen gadol to the nasi , but this is rejected. The nasi is included in the communal Yom Kippur offering, whereas the kohen gadol receives atonement through his own unique Yom Kippur sacrifice. Ultimately, the source is derived from the verse "עַל חַטָּאתוֹ אֲשֶׁר חָטָא" ("for the sin which he sinned," Vayikra 4:3). Rava and Abaye disagree about whether the earlier case—where the kohen gadol and the court ruled simultaneously—refers to rulings made in the same location or in different places. The Gemara explores various scenarios in which the kohen gadol and the court ruled on different matters. Some cases are obvious, while others remain uncertain. The Mishna further explains that the kohen gadol's sacrifice resembles the communal sin offering in that both require two conditions: (1) a mistaken ruling that leads to erroneous instruction, and (2) an unwitting action based on that ruling. The same principle applies to idol worship—to be liable, there must be both an erroneous ruling and a subsequent action. A braita derives this from a gezeira shava based on the phrase "מֵעֵינֵי" ("from the eyes"). When the Mishna states that the same applies to idol worship, it does not explicitly say, "And the same is true for the kohen gadol," as it did earlier. Initially, the Gemara interprets this to mean that the Mishna follows Rebbi, who holds that the kohen gadol brings a sacrifice for idol worship based solely on an unwitting action, even without a mistaken ruling. However, this interpretation is rejected, and the Mishna is re-explained as the sentence "And such is true for the kohen gadol" would apply to both the sentence before and the sentence after, as is the case in the upcoming Mishna.
