Parashas Metzora · Passuk 14:04
Chabad.org — English translation + Rashi
Torah Temima points to Toras Kohanim.
English: “And the kohen shall command and he shall take” — the command is by the kohen, but the taking may be performed by any person.
Distinction of roles
Chazal teach that only the command must issue from a kohen; the actual collection of the birds and materials may be performed by anyone.
