Leviticus 13:47-49

New Catholic Bible

⁴⁷ Infections in Fabrics.“When a garment has a leprous mark on it, whether it be a woolen garment or a linen garment, ⁴⁸ whether it is in the weave or the knit of the wool or the linen, or if it is a skin or anything made of a skin, ⁴⁹ if there is a green or red spot on the garment or the skin, whether in the weave or the knit or on anything made of skin, it is to be considered a mark of leprosy and it is to be shown to the priest.
