"Now suppose an infectious mildew contaminates some woolen or linen clothing,
References for Leviticus 13:47
some woolen or linen fabric, the hide of an animal, or anything made of leather.
If the affected area in the clothing, the animal hide, the fabric, or the leather has turned bright green or a reddish color, it is contaminated with an infectious mildew and must be taken to the priest to be examined.
After examining the affected spot, the priest will put it away for seven days.
On the seventh day the priest must inspect it again. If the affected area has spread, the material is clearly contaminated by an infectious mildew and is unclean.
The priest must burn the linen or wool clothing or the piece of leather because it has been contaminated by an infectious mildew. It must be completely destroyed by fire."
"But if the priest examines it again and the affected spot has not spread in the clothing, the fabric, or the leather,
the priest will order the contaminated object to be washed and then isolated for seven more days.
Then the priest must inspect the object again. If he sees that the affected area has not changed appearance after being washed, even if it did not spread, the object is defiled. It must be completely burned up, whether it is contaminated on the inside or outside.
But if the priest sees that the affected area has faded after being washed, he is to cut the spot from the clothing, the fabric, or the leather.
If the spot reappears at a later time, however, the mildew is clearly spreading, and the contaminated object must be burned up.
But if the spot disappears after the object is washed, it must be washed again; then it will be ceremonially clean."
"These are the instructions for dealing with infectious mildew in woolen or linen clothing or fabric, or in anything made of leather. This is how the priest will determine whether these things are ceremonially clean or unclean."
