Context
49 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.
50 The priest shall examine the plague, and isolate the plague seven days.
51 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.
