(58) And the garment . . . --According to Leviticus 13:54; Leviticus 13:56, the suspicious symptoms often disappeared after the stuffs had been washed and put in quarantine for a week, thus showing that it was not real leprosy. But though non-leprous, the garments had to be washed a second time before they could be pronounced fit for use.

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.And the garment, either warp or woof, or whatsoever thing of skin it be, which thou shalt wash,.... After it had been shut up seven days, and viewed by the priest again: if the plague be departed from them: upon a review of them:

then it shall be washed the second time, and shall be clean; and so reckoned even thoroughly clean, and used; this denotes the thorough washing and cleansing of sinners by the blood of Jesus, see Psalm 51:2; this washing was by dipping; and so the Targum renders it; and Jarchi observes, that all washings of garments, which are for dipping, they interpret by the same word.
