Moreover, all his days he eats in darkness, with much sorrow, sickness, and anger.
Solomon had shown the vanity of pleasure, gaiety, and fine works, of honour, power, and royal dignity; and there is many a covetous worldling that will agree with him, and speak as slightly as he does of these things; but money, he thinks, is a substantial thing, and if he can but have enough of that he is happy.
Commenting on Ecclesiastes 5:9-17
All his days also he eateth in darkness,.... To all that has been said is added another evil, that attends such whose hearts are inordinately set on riches; that all their days, throughout the whole of their lives, they live a most uncomfortable life; for eating is here put for their whole manner of living: such not only eat coarse bread, and very mean food...
eateth--appropriately put for "liveth" in general, as connected with Ecc 5:11-12, Ecc 5:18. darkness--opposed to "light (joy) of countenance" (Ecc 8:1; Pro 16:15). wrath--fretfulness, literally, "His sorrow is much, and his infirmity (of body) and wrath."
