Leviticus 13:49-51

New Living Translation

⁴⁹ If the contaminated area in the clothing, the animal hide, the fabric, or the leather article has turned greenish or reddish, it is contaminated with mildew and must be shown to the priest. 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.
