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 mould has spread in the fabric, the woven or knitted material, or the leather, whatever its use, it is a persistent defiling mould; 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 mould is persistent; the article must be burned.
53. ‘But if, when the priest examines it, the mould 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.
55. After the article has been washed, the priest is to examine it again, and if the mould has not changed its appearance, even though it has not spread, it is unclean. Burn it, no matter which side of the fabric has been spoiled.
56. If, when the priest examines it, the mould has faded after the article has been washed, he is to tear the spoiled part out of the fabric, the leather, or the woven or knitted material.
57. But if it reappears in the fabric, in the woven or knitted material, or in the leather article, it is a spreading mould; whatever has the mould must be burned.
58. Any fabric, woven or knitted material, or any leather article that has been washed and is rid of the mould, must be washed again. Then it will be clean.’
59. These are the regulations concerning defiling moulds in woollen or linen clothing, woven or knitted material, or any leather article, for pronouncing them clean or unclean.
