Leviticus 13:50-54 New International Version (NIV)

50. The priest is to examine the affected area and isolate the article for seven days.

51. On the seventh day he is to examine it, and if the mold has spread in the fabric, the woven or knitted material, or the leather, whatever its use, it is a persistent defiling mold; the article is unclean.

52. He must burn the fabric, the woven or knitted material of wool or linen, or any leather article that has been spoiled; because the defiling mold is persistent, the article must be burned.

53. “But if, when the priest examines it, the mold has not spread in the fabric, the woven or knitted material, or the leather article,

54. he shall order that the spoiled article be washed. Then he is to isolate it for another seven days.
