Leviticus 13:52

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 ) .
