Leviticus 13:50-52

The Voice

⁵⁰ The priest must examine the article and quarantine it for seven days. ⁵¹ When the seventh day arrives, the priest must check it again; and if the affected area has spread to other parts of the article—whether in the wool, linen, or leather, regardless of what the leather was used for—the article has a serious outbreak which makes it unclean. ⁵² So the priest has to burn the garment—whether it is made of wool, linen or leather—because it has some serious outbreak like leprosy and must be destroyed by fire.
