English: “And the kohen shall cause to go up in smoke” — why does it say “the kohen”? To exclude stripping and cutting [from being restricted to kohanim].
In the sugya: Specifying “the kohen” on hakatarah implies that not every prior step is kohen-only. Hafshatah and nituach are the classic examples of acts a zar may also perform.
Type of Learning
Miyut from “the kohen” on hakatarah — stripping and cutting are not kohen-restricted.
What Is Learned
Acts belonging to the body of the burning are done by kohanim; hafshatah and nituach may also be done by a zar. The word “the kohen” on the smoking is what draws that boundary.
