Kommentar zu Wajikra 7:2

שחטו THEY SHALL SLAUGHTER — By using the plural ישחטו Scripture speaks of “several slaughterers” in connection with the עולה ‎‎‎‎(ישחטו את עולה)‎ ” in order to include also the communal burnt-offering under the law that an עולה must be slaughtered on the north side of the altar. — Since we do not find a guilt-offering in the case of the whole community, the term ישחטו in the plural is used here (ישחטו את האשם) because Scripture brings it in connection with the עולה (i. e. since the plural is used of the עולה it balances it by the same expression in the next phrase) (cf. Sifra, Tzav, Section 5 3).
