James 5:1-6 in The Moffatt Translation of the Bible
Come now you rich men,
weep and shriek over your impending miseries!
You have been storing up treasure in the very last days;
Your wealth lies rotting and your clothes are moth-eaten;
your gold and silver lie rusted over,
and their rust will be evidence against you,
it will devour your flesh like fire.
See, the wages of which you have defrauded
the workmen who mowed your fields call out,
and the cries of the harvesters
have reached the ears of The Lord of Hosts,
You have reveled on the earth and plunged into dissipation,
You have fattened yourselves as for the Day of slaughter,
You have condemned,
you have murdered the righteous unresisting.
When I read this the first time, the first half of the passage about the moth-eaten clothing and the rusted gold and silver being "evidence" against the rich man jumped out at me. The tangibility of the evidence! It is not something only God can see or judge. It is right there for all to see. This moth-eaten and rusted evidence got in this condition through lack of use. While others suffered, the rich were piling up stuff they couldn't even use.
And now, on a second look I see more. The rich had amassed their wealth on the backs of people who so needed an income they didn't even protest the low wages.
Not only can God see the initial tangible evidence, He has heard the cries of the defrauded poor. Here is His take on the rich in this passage: You are partying and having a great time, or so you think. In actuality you are fattening yourselves up to be slaughtered.
Oh the irony!
