Leviticus 13:49-51

New Revised Standard Version, Anglicised

⁴⁹ if 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^[a] disease and shall be shown to the priest. ⁵⁰ The priest shall examine the disease, and put the diseased article aside for seven days. ⁵¹ He shall examine the disease on the seventh day. If the disease has spread in the cloth, in warp or woof, or in the skin, whatever be the use of the skin, this is a spreading leprous^[b] disease; it is unclean.
