But if the spot is white in the skin of his body, and appears no deeper than the skin, and the hair in it has not turned white, the priest shall shut up the diseased person for seven days;
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 disease and shall be shown to the priest.
then he shall examine the disease on the seventh day. If the disease has spread in the garment, in warp or woof, or in the skin, whatever be the use of the skin, the disease is a malignant leprosy; it is unclean.
