Leviticus 13:48-50

New Catholic Bible

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. ⁵⁰ The priest shall look at the spot, and shall secure that thing that is infected for seven days.
