He shall therefore burn that garment
 That there may be no more use of it, nor profit from it; and this was done without the city, as Ben Gersom asserts: 
 whether in warp or woof, in woollen or in linen, or anything of skin,
 wherein the plague is;
 all and either of them were to be burnt: 
for it [is] a fretting leprosy; (See Gill on Leviticus 13:51):
 it shall be burnt in the fire;
 which may teach both to hate the garment spotted with the flesh, and to put no trust in and have no dependence on a man's own righteousness, which is as filthy rags, and both are such as shall be burnt, and the loss of them suffered, even when a man himself is saved, yet so as by fire, ( 1 Corinthians 3:15 ) .
