Leviticus 13:52

48whether it is in warp or woof; of linen or of wool; whether in leather, or in anything made of leather;

49if the plague is greenish or reddish in the garment, or in the leather, or in the warp, or in the woof, or in anything made of leather; it is the plague of leprosy, and shall be shown to the priest.

50The priest shall examine the plague, and isolate the plague seven days.

51He shall examine the plague on the seventh day. If the plague has spread in the garment, either in the warp, or in the woof, or in the skin, whatever use the skin is used for, the plague is a destructive mildew. It is unclean.

52He shall burn the garment, whether the warp or the woof, in wool or in linen, or anything of leather, in which the plague is, for it is a destructive mildew. It shall be burned in the fire.

53“If the priest examines it, and behold, the plague hasn’t spread in the garment, either in the warp, or in the woof, or in anything of skin;

54then the priest shall command that they wash the thing that the plague is in, and he shall isolate it seven more days.

55Then the priest shall examine it, after the plague is washed; and behold, if the plague hasn’t changed its color, and the plague hasn’t spread, it is unclean; you shall burn it in the fire. It is a mildewed spot, whether the bareness is inside or outside.

56If the priest looks, and behold, the plague has faded after it is washed, then he shall tear it out of the garment, or out of the skin, or out of the warp, or out of the woof;
