Leviticus 13:53, 54, 58, 59
But when the priest reexamines it, if the mildew has not spread in the fabric, weave, knit, or leather article, / the priest is to order the contaminated article to be washed and isolated for another seven days. / If the mildew disappears from the fabric, weave, or knit, or any leather article after washing, then it is to be washed again, and it will be clean.
