Parashas Acharei Mos · Passuk 16:26
Chabad.org — English translation + Rashi
Torah Temima points to Yoma 67b.
English: “And the one who sends” — the sender of the goat renders garments tamei, but the one who dispatches the sender does not.
Halachic scope of tumat begadim
Only the person who actually escorts the goat to Azazel contracts the garment-impurity; intermediaries who merely appoint him do not.
