James 5:2 - Matthew Poole's English Annotations on the Holy Bible

Your riches are corrupted: either by riches he means the general, and by garments, gold and silver, the particulars in which their riches consisted; and then being corrupted, is to be taken generally, as comprehending the several ways whereby the several kinds of their riches were spoiled: or else, by riches he understands such things as were liable to corruption, or putrefaction, as corn, wine, oil, which were a great part of their riches. And your garments are moth-eaten; costly garments, in which rich men are wont to pride themselves; and under them may be comprehended all such clothes as may be eaten by worms or moths.
