Leviticus 13:52-54

New King James Version

⁵² He shall therefore burn that garment in which is the plague, whether warp or woof, in wool or in linen, or anything of leather, for it is an active leprosy; the garment shall be burned in the fire.

⁵³ “But if the priest examines it, and indeed the plague has not spread in the garment, either in the warp or in the woof, or in anything made of leather, ⁵⁴ then the priest shall command that they wash the thing in which is the plague; and he shall isolate it another seven days.
