“And is guilty” — one does not bring asham talui for a positive or negative commandment of the sanctuary; only for doubt of a fixed chatas.
In the sugya: Doubts about sanctuary impurity follow their own path (the oleh ve-yored structure), not the asham talui. Asham talui is reserved for cases that would otherwise generate a fixed chatas.
Type of Learning
Hekesh to communal asham structure — sanctuary-tumah doubts excluded.
What Is Learned
Sanctuary impurity doubts follow their own oleh ve-yored path, not asham talui. The obligation of asham talui is limited to doubts that, if resolved toward guilt, would require a fixed chatas offering.
