Leviticus 13:47-59

⁴⁷"When there is a leprous disease in a garment, whether a woolen or a linen garment, ⁴⁸in warp or woof of linen or wool, or in a skin or in anything made of skin, ⁴⁹if the disease shows greenish or reddish in the garment, whether in warp or woof or in skin or in anything made of skin, it is a leprous disease and shall be shown to the priest. ⁵⁰And the priest shall examine the disease, and shut up that which has the disease for seven days; ⁵¹then he shall examine the disease on the seventh day. If the disease has spread in the garment, in warp or woof, or in the skin, whatever be the use of the skin, the disease is a malignant leprosy; it is unclean. ⁵²And he shall burn the garment, whether diseased in warp or woof, woolen or linen, or anything of skin, for it is a malignant leprosy; it shall be burned in the fire.

⁵³"And if the priest examines, and the disease has not spread in the garment in warp or woof or in anything of skin, ⁵⁴then the priest shall command that they wash the thing in which is the disease, and he shall shut it up seven days more; ⁵⁵and the priest shall examine the diseased thing after it has been washed. And if the diseased spot has not changed color, though the disease has not spread, it is unclean; you shall burn it in the fire, whether the leprous spot is on the back or on the front.

⁵⁶"But if the priest examines, and the disease is dim after it is washed, he shall tear the spot out of the garment or the skin or the warp or woof; ⁵⁷then if it appears again in the garment, in warp or woof, or in anything of skin, it is spreading; you shall burn with fire that in which is the disease. ⁵⁸But the garment, warp or woof, or anything of skin from which the disease departs when you have washed it, shall then be washed a second time, and be clean."

⁵⁹This is the law for a leprous disease in a garment of wool or linen, either in warp or woof, or in anything of skin, to decide whether it is clean or unclean.
