52 And the clothing, or the wool or linen material, or anything of leather in which is the disease, is to be burned: for the disease is biting into it; let it be burned in the fire. 53 And if the priest sees that the mark is not increased in the clothing or in any part of the material or in the leather, 54 Then the priest will give orders for the thing on which the mark is, to be washed, and to be shut up for seven days more: 55 And if, after the mark has been washed, the priest sees that the colour of it is not changed and it is not increased, it is to be burned in the fire: the disease is working in it, though the damage may be inside or outside. 56 And if the priest sees that the mark is less bright after the washing, then let him have it cut out of the clothing or the leather or from the threads of the material: 57 And if the mark is still seen in the clothing or in the threads of the material or in the leather, it is the disease coming out: the thing in which the disease is will have to be burned with fire.
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.
