Torah Temimah points to Toras Kohanim (Sifra), Vayikra Dibbura DeChovah, on 4:8.
Sefaria — Sifra / Toras Kohanim, Vayikra Dibbura DeChovah
English: “The fat of the chatas bull” — like the fat of the shelamim sacrifice.
Parallel of shelamim emurim for the High Priest’s bull — the emurim of the High Priest’s chatas follow the shelamim list.
The emurim of the High Priest’s chatas follow the shelamim list. The Sifra’s comparison of “the fat of the chatas bull” to the fat of the shelamim teaches that the same portions (the covering fat of the innards and the fat upon the innards) are removed and offered. This creates a consistent framework for the sacrificial fats across different offerings that share this structural language.
