Leviticus 13:53

And he shall look on the plague on the seventh day: if the plague be spread in the garment, either in the warp, or in the woof, or in a skin, [or] in any work that is made of skin; the plague [is] a fretting leprosy; it [is] unclean.

He shall therefore burn that garment, whether warp or woof, in woollen or in linen, or any thing of skin, wherein the plague is: for it [is] a fretting leprosy; it shall be burnt in the fire.

Then the priest shall command that they wash [the thing] wherein the plague [is], and he shall shut it up seven days more:

And the priest shall look on the plague, after that it is washed: and, behold, [if] the plague have not changed his colour, and the plague be not spread; it [is] unclean; thou shalt burn it in the fire; it [is] fret inward, [whether] it [be] bare within or without.
