52 The priest must burn the item-the clothing, the woolen or linen fabric, or piece of leather-for it has been contaminated by a serious mildew. It must be completely destroyed by fire. 53 "But if the priest examines it and finds that the contaminated area has not spread in the clothing, the fabric, or the leather, 54 the priest will order the object to be washed and then quarantined for seven more days. 55 Then the priest must examine the object again. If he finds that the contaminated area has not changed color after being washed, even if it did not spread, the object is defiled. It must be completely burned up, whether the contaminated spot is on the inside or outside. 56 But if the priest examines it and finds that the contaminated area has faded after being washed, he must cut the spot from the clothing, the fabric, or the leather. 57 If the spot later reappears on the clothing, the fabric, or the leather article, the mildew is clearly spreading, and the contaminated object must be burned up.
Matthew Henry's Commentary on Leviticus 13:52-57
Commentary on Leviticus 13:47-59
(Read Leviticus 13:47-59)
The garment suspected to be tainted with leprosy was not to be burned immediately. If, upon search, it was found that there was a leprous spot, it must be burned, or at least that part of it. If it proved to be free, it must be washed, and then might be used. This also sets forth the great evil there is in sin. It not only defiles the sinner's conscience, but it brings a stain upon all he has and all that he does. And those who make their clothes servants to their pride and lust, may see them thereby tainted with leprosy. But the robes of righteousness never fret, nor are moth-eaten.
