Leviticus 13:48

“The leper in whom the plague is shall wear torn clothes, and the hair of his head shall hang loose. He shall cover his upper lip, and shall cry, ‘Unclean! Unclean!’

All the days in which the plague is in him he shall be unclean. He is unclean. He shall dwell alone. His dwelling shall be outside of the camp.

“The garment also that the plague of leprosy is in, whether it is a woolen garment, or a linen garment;

if 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.

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

He 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.
