Leviticus 13:52-54

Expanded Bible

⁵² The priest must burn the clothing. It does not matter if it is woven or knitted, wool or linen, or made of leather, because the mildew is spreading. It must be burned.

⁵³ “If the priest sees that the mildew [13:47] has not spread in the cloth (either knitted or woven) or leather, ⁵⁴ he must order the people to wash that piece of leather or cloth. Then he must ·separate [confine; quarantine] the clothing for seven more days.
