Torah Temimah points to Toras Kohanim (Sifra), Vayikra Dibbura DeChovah, on 4:13 (ve-ashemu — community punished like individual) (unit 11; single primary locus per emergency Core plan).
Sefaria — Sifra / Toras Kohanim, Vayikra Dibbura DeChovah
English: “And they are guilty” — this teaches that just as one exacts from the individual, so one exacts from the community.
Parallel of communal and individual liability — the community is held to account for shegagah just as an individual is.
The word “ve-ashemu” places the congregation under the same framework of accountability that governs the individual. Just as a private person who sins in error must bring a chatas, so the community that sins through its court and its people must bring its own chatas. The verse refuses to exempt the public from the ordinary demands of atonement.
