Riches

James 5:1-6  Go to now, you rich men, weep and howl for your miseries that shall come upon you. Your riches are corrupted, and your garments are moth-eaten. Your gold and silver is cankered; and the rust of them shall be a witness against you, and shall eat your flesh as it were fire. You have heaped treasure together for the last days. Behold, the hire of the labourers who have reaped down your fields, which is of you kept back by fraud, cries: and the cries of them which have reaped are entered into the ears of the Lord of Sabaoth. You have lived in pleasure on the earth, and been wanton; you have nourished your hearts, as in a day of slaughter.  You have condemned and killed the just; and he doth not resist you. 

These verses contain the first and last prophecy in James regarding six predictions concerning evil rich men that awaits them because they have condemned and killed the just.

Miseries will come upon them, their riches will become corrupted and their garments moth-eaten, their gold and silver to canker that eat their flesh and the rust or poison of their riches will witness or testify of their many sins. These riches that are corrupted instead of cankered as gold and silver, refers to crops, flocks, stores of grain, wine, oil, and many changes of clothing in the wardrobes.

Lord of Sabaoth is a term often used in the Old Testament of God who is Lord of hosts, or Lord of armies, who has infinite power to rule the nations and punish the wicked (1Sam. 1:3, 11; 4:4; 15:2).

Living in pleasure on earth – the Greek word truphao which means to live softly or delicately; fare sumptuously; live in luxury; to be effeminate; to be licentious; to revel – and been wanton is the Greek word spatalao that refers to living riotously and in pleasure (1Tim. 5:6; 1 Pet. 4:3); and nourishing of the hearts as in the day of slaughter refers to feasting and surfeiting as men do at the times of their religious feasts.
