TT #280 · Parshas Tazria · Aliyah 7 · Passuk 51
English: The priest shall examine the lesion on the seventh day; if it has spread in the garment, warp or woof, or leather article, the lesion is malignant tzaraas; it is impure.
Torah Temimah cites Sifra (Toras Kohanim) for extending the prohibition on benefit to a garment still under quarantine.
Sifra — Vayikra 13, Midrash Sefer
English: How do we include a garment still under quarantine in the prohibition on benefit? The verse says, “for it is tzaraas.”
Textual derivation
The prohibition on benefit begins even during quarantine; one may not use the garment while awaiting the priest’s final ruling. The next unit treats the separate rule for a garment that has been definitively declared impure.
