Leviticus 13:46-50

He shall remain unclean all the days during which he has the infection; he is unclean. He shall live alone; he shall live outside the camp.

“When a garment has a mark of leprosy in it, whether it is a wool garment or a linen garment,

whether in warp or woof, of linen or of wool, whether in leather or in any article made of leather,

if the mark is greenish or reddish in the garment or in the leather, whether in the warp or in the woof, or in any article of leather, it is a leprous mark and it shall be shown to the priest.

Then the priest shall look at the mark and shall quarantine the article with the mark for seven days.
