Jas 5:4

“Behold, the wages of the workers who have reaped your fields, which were withheld by you, cry out. How great is the iniquity of the proud, who, although they have sufficient wealth, not only disdain to welcome and refresh the poor coming everywhere, but also refuse to give the due wages of their work to the laborers or their servants. This fault of impiety the blessed Job indicates that he took great care to avoid, as he says: If my land cries out against me, and its furrows weep together, if I have eaten its fruits without money, and afflicted the soul of its tillers, let thorns grow instead of wheat, and thistles instead of barley (Job 31). And their cry has entered into the ears of the Lord of Hosts. He calls the Lord of Hosts to instill fear in those who think that the poor have no protector. But to this place suits that of the Psalmist: "For the poor are left to you, you will be a helper to the orphan" (Psa. Heb. 10). And what is written in the book of the blessed Job: "For God will not hear in vain, and the Almighty will consider the causes of each one" (Job 35). You have feasted on the earth. Having neglected the heavenly joys to which you could have come through afflictions and fasts, you only love carnal feasts, which will be followed by such great hunger and thirst in the future, that not even a single drop of water can then be obtained from elsewhere to cool your burning tongue.”

“This is an exposure and shaming of the Jewish leaders, who tended the poor and glutted themselves with honors from all, but were themselves being prepared for slaughter at the hands of the Roman authorities, especially for having condemned the only Righteous One — the Lord — and killed Him when He did not resist, did not cry out.”

“Behold--calling attention to their coming doom as no vain threat. labourers--literally "workmen." of you kept back--So English Version rightly. Not as ALFORD, "crieth out from you." The "keeping back of the hire" was, on the part OF the rich, virtually an act of "fraud," because the poor laborers were not immediately paid. The phrase is therefore not, "kept back by you," but "of you"; the latter implying virtual, rather than overt, fraud. James refers to Deu 24:14-15, "At this day . . . give his hire, neither shall the sun go down upon it, lest he CRY against thee unto the Lord, and it be sin unto thee." Many sins "cry" to heaven for vengeance which men tacitly take no account of, as unchastity and injustice [BENGEL]. Sins peculiarly offensive to God are said to "cry" to Him. The rich ought to have given freely to the poor; their not doing so was sin. A still greater sin was their not paying their debts. Their greatest sin was not paying them to the poor, whose wages is their all. cries of them--a double cry; both that of the hire abstractly, and that of the laborers hired. the Lord of sabaoth--here only in the New Testament. In Rom 9:29 it is a quotation. It is suited to the Jewish tone of the Epistle. It reminds the rich who think the poor have no protector, that the Lord of the whole hosts in heaven and earth is the guardian and avenger of the latter. He is identical with the "coming Lord" Jesus (Jam 5:7).”
