Leviticus 13:52-56

⁵²And he shall then burn that garment, whether warp or woof, in woollen or in linen, or any article of skin, whereon the plague is; for it is a corroding leprosy, in fire shall it be burnt.

⁵³And if the priest shall see, and, behold, the plague have not spread on the garment, either on the warp, or on the woof, or on any article of skin:

⁵⁴Then shall the priest command that they wash the thing whereon the plague is, and he shall shut it up seven days more.

⁵⁵And if the priest see, after the plague hath been washed, and, behold, the plague have not changed its color, and the plague have not spread: it is unclean, in fire shalt thou burn it; it is a decay on its inside or on its outside.

⁵⁶And if the priest see, and, behold, the plague have become pale after its having been washed: then shall he tear it out from the garment, or from the skin, or from the warp, or from the woof.
