Leviticus 13:47-52

47“Now about clothing—if there is a green or red area on a piece of clothing

48that is woven or knitted from linen or wool or on any leather article,

49it is mildew. It must be shown to the priest.

50The priest will examine the mildew and will put the clothing in a separate place for seven days.

51On the seventh day he will examine the area again. If the spot is spreading, it is unclean.

52He must burn the piece of clothing or the leather article because the mildew is growing.
