Your riches are corrupted
Either through disuse of them; and so the phrase is expressive of
their tenaciousness, withholding that from themselves and others
which is meet, and which is keeping riches for the owners
thereof, to their hurt; or these are corrupted, and are
corruptible things, fading and perishing, and will stand in no
stead in the day of wrath, and therefore it is great weakness to
put any trust and confidence in them:
and your garments are moth eaten;
being neither wore by themselves, nor put upon the backs of
others, as they should, but laid up in wardrobes, or in chests
and coffers, and so became the repast of moths, and now good for
nothing.
