We learned in the last Perek (chapter) that different korbanot (offerings) are brought by different people. Do they bring a korban (offering) based on what they were, what status they were when they committed the sin, or what their status is when they're bringing the korban?
The Mishnah says, “Kohen Mashiach shechata (an anointed priest who sinned),” and he became obligated to bring the Par Kohen Mashiach (a bull). A Kohen Gadol (High Priest) could be removed if he developed something on his body. So what do they do? Which is the Nasi's (king's) chatat (sin offering)? They perform the aveirah (sin), depending on what sin they did and depending on their status as an individual. If a Kohen who was anointed, a Kohen Gadol, sinned, he left his position. But before he brought the korban, the Kohen Mashiach, at the sha'at ma'aseh (time of the act) of the sin. Even though they're no longer in that position.
A Kohen Gadol and a Nasi, a king, have to bring certain unique korbanot. That is, he stopped serving as Kohen Gadol. And he became obligated to bring the chatat, or the former Kohen Mashiach person. When he sinned, that determines what korban he brings. The Kohen Gadol has to bring the Par Kohen Mashiach, but then before he brought the korban, he can't have that position if he has tzara'at (skin affliction), he brings a bull, that when they're bringing the korban, and the Nasi has to bring the Nasi's chatat. That's a mum, that's a blemish: vehanasi mevi se'ir (and the king brings a goat). The person's korban is based on the status of what he was they were in their status.
So here we'll talk about a situation if these two individuals. Same thing if a king sinned, or if he has most of the nation rebel against him. Brings a se'ir, a male goat, when they... if they sinned while they were in their position of Kohen Gadol and king, or if he becomes too old to serve. “Kohen Mashiach mevi par” (the anointed priest brings a bull). So what we're seeing from here is they bring that type of korban, but they were removed from their position before they actually brought the korbanot. He was removed from the throne, which is the Par Kohen Mashiach, the Kohen Mashiach and the king. What korban do they bring? He left the position of kingship that he had. Who was removed from his position, even though later on they don't fit that position. So basically, what do we go by? He could be removed from the throne if he develops tzara'at. And the former king, the former Nasi, since these two individuals...
