And he shall burn the garment, or the warp, or the woof, whether it be of wool or of linen, or any thing of skin, wherein the plague is; for it is a malignant leprosy; it shall be burnt in the fire.
Mishnah Negaim
[If a nega] appeared on the standing warp, the already woven cloth remains clean. If it appeared on the already woven cloth, the standing warp remains clean. If it appeared on a sheet, he must also burn the fringes. If it appeared on the fringes the sheet remains clean. A shirt on which a nega appeared affords protection to its hems, even though they are of purple wool.
Mishnah Negaim
If a garment that had been isolated was mixed up with others, all are clean. If it was cut up and made into shreds, it is clean, and benefit may be derived from it. But if a garment that had been certified unclean was mixed up with others, all are unclean. If it was cut up and made into shreds it also remains unclean and it is forbidden to have any benefit from it.
