English: “For the guilt of the people” — he is an anointed [priest] like the community. Just as the community brings only for a forgotten matter together with an inadvertent act, so the anointed [priest] brings only for a forgotten matter together with an inadvertent act.
Equivalence of Mashiach to tzibbur — the anointed High Priest brings his bull only under the same conditions as the communal chatas (forgotten matter + inadvertent act).
The anointed High Priest brings his bull only for a forgotten matter together with an inadvertent act, exactly as the community does. The Torah’s phrase “for the guilt of the people” establishes that the High Priest’s special chatas is governed by the same dual requirement that governs the communal bull. This keeps the personal offering of the High Priest within the communal paradigm rather than expanding it to ordinary individual shogeg alone.
