Torah Temimah points to Toras Kohanim (Sifra), Vayikra Dibbura DeChovah, on 4:24 (chatas hu — all its acts for the sake of chatas) (unit 6; single primary locus per emergency Core plan).
Sefaria — Sifra / Toras Kohanim, Vayikra Dibbura DeChovah
English: “It is a chatas” — why is this said? To teach that all its acts must be for the sake of a chatas.
All avodot lishmah for chatas — every stage of the nasi’s offering must be performed with chatas intent.
Not only the shechitah but every later act — kabbalah, holachah, zerikah — must be done for the sake of a chatas. An act performed with intent for a different offering-type invalidates the service. The midrash reads the verse as imposing a comprehensive lishmah requirement on the entire sequence of avodot.
