Side-ring EXTRA · The bull must be from his own property
The doubled phrase “par hachatat asher lo” is expounded in Yoma and Chullin: the bull must come from the Kohen Gadol’s private means, not from public funds or from the other Kohanim.
English: “Which is his” — he brings it from his own property, and not from the community.
Private ownership of the chatas bull
Even though the Kohanim receive kapparah through this bull, it must still be purchased from the Kohen Gadol’s personal funds. Public money and even the property of the other Kohanim are excluded.
