5 In pleasure. He comes now to another vice, even luxury and sinful gratifications; for they who abound in wealth seldom keep within the bounds of moderation, but abuse their abundance by extreme indulgences. There are, indeed, some rich men, as I have said, who pine themselves in the midst of their abundance. For it was not without reason that the poets have imagined Tantalus to be hungry near a table well furnished. There have ever been Tantalians in the world. But James, as it has been said, does not speak of all rich men. It is enough that we see this vice commonly prevailing among the rich, that they are given too much to luxuries, to pomps and superfluities.
And though the Lord allows them to live freely on what they have, yet profusion ought to be avoided and frugality practiced. For it was not in vain that the Lord by his prophets severely reproved those who slept on beds of ivory, who used precious ointments, who delighted themselves at their feasts with the sound of the harp, who were like fat cows in rich pastures. For all these things have been said for this end, that we may know that moderation ought to be observed, and that extravagance is displeasing to God.
Ye have nourished your hearts. He means that they indulged themselves, not only as far as to satisfy nature, but as far as their cupidity led them. He adds a similitude, as in a day of slaughter, because they were wont in their solemn sacrifices to eat more freely than according to their daily habits. He then says, that the rich feasted themselves every day of their life, because they immersed themselves in perpetual indulgences.
