Leviticus 13:50-52

Living Bible

⁵⁰ The priest will put it away for seven days ⁵¹ and look at it again on the seventh day. If the spot has spread, it is a contagious leprosy, ⁵² and he must burn the clothing, fabric, linen or woolen covering, or leather article, for it is contagious and must be destroyed by fire.
