E-Daf.com — Pesachim 75a
HebrewBooks / Shas PDF
English: “It shall be burned” — that it be burned even if there is no ash there and even if the fire has already taken hold of most of it.
Burning continues regardless of ash or partial ignition — once started, the burning is completed even without prior ash and even after most of the animal has caught fire.
The command to burn is not frustrated by the absence of prior deshen or by the fire’s early success. Even if the site lacks ash and even if the majority of the carcass has already ignited, the remaining portions must still be brought to complete combustion. The verse’s language sustains the duty through every stage of the process.
