Leviticus 13:50-52

New Living Translation

⁵⁰ After examining the affected spot, the priest will put the article in quarantine for seven days. ⁵¹ On the seventh day the priest must inspect it again. If the contaminated area has spread, the clothing or fabric or leather is clearly contaminated by a serious mildew and is ceremonially unclean. ⁵² The priest must burn the item—the clothing, the woolen or linen fabric, or piece of leather—for it has been contaminated by a serious mildew. It must be completely destroyed by fire.
