Psalms 31:10

For my life is spent with grief, and my years with sighing,....

Though the effects ascribed to grief are not mere figures of speech-- spent . . . consumed--must be taken in the modified sense of wasted and decayed. iniquity--or, suffering by it (see on Ps 40:12).

For my life is spent with grief, and my years with sighing. It had become his daily occupation to mourn; he spent all his days in the dungeon of distress. The sap and essence of his existence was being consumed, as a candle is wasted while it burns. His adversities were shortening his days, and digging for him an early grave. Grief is a sad market to spend all our wealth of life in, but a far more profitable trade may be driven there than in Vanity Fair; it is better to go to the house of mourning than the house of feasting. Black is good wear. The salt of tears is a healthy medicine. Better spend our years in sighing than in sinning. The two members of the sentence before us convey the same idea; but there are no idle words in Scripture, the reduplication is the fitting expression of fervency and importunity. My strength faileth because of mine iniquity. David sees to the bottom of his sorrow, and detects sin lurking there. It is profitable trouble which leads us to trouble ourselves about our iniquity. Was this the psalmist's foulest crime which now gnawed at his heart, and devoured his strength? Very probably it was so. Sinful morsels, though sweet in the mouth, turn out to be poison in the bowels: if we wantonly give a portion of our strength to sin, it will by and by take the remainder from us. We lose both physical, mental, moral, and spiritual vigour by iniquity. And my bones are consumed. Weakness penetrated the innermost parts of his system, the firmest parts of his frame felt the general decrepitude. A man is in a piteous plight when he comes to this.

My life is spent with grief - My life is a life of suffering and distress, and by grief my days are shortened. Grief disturbs the functions of life, prevents the due concoction of food, injures the digestive organs, destroys appetite, impairs the nervous system, relaxes the muscles, induces morbid action in the animal economy, and hastens death. These effects are well expressed in the verse itself. My years with sighing - אנחה anachah. This is a mere natural expression of grief; the very sounds which proceed from a distressed mind; an-ach-ah! common, with little variation, to all nations, and nearly the same in all languages. The och-och-on of the Irish is precisely the same sound, and the same sense. Thousands of beauties or this kind are to be found in the sacred language.

For my life is spent with grief - The word here rendered “spent” does not mean merely “passed,” as it is commonly now used, as when we say we “spent” our time at such a place, or in such a manner, but in the more proper meaning of the word, as denoting “consumed, wasted away,” or “destroyed.” See the word כלה kâlâh as used in Jer 16:4; Lam 2:11; Psa 84:2 (Heb. 3); Psa 143:7; Psa 69:3 Heb. 4; Job 11:20. And my years with sighing - That is, my years are wasted or consumed with sighing. Instead of being devoted to active toil and to useful effort, they are exhausted or wasted away with a grief which wholly occupies and preys upon me. My strength faileth because of mine iniquity - Because of the trouble that has come upon me for my sin. He regarded all this trouble - from whatever quarter it came, whether directly from the hand of God, or from man - as the fruit of “sin.” Whether he refers to any particular sin as the cause of this trouble, or to the sin of his nature as the source of all evil, it is impossible now to determine. Since, however, no particular sin is specified, it seems most probable that the reference is to the sin of his heart - to his corrupt nature. It is common, and it is not improper, when we are afflicted, to regard all our trials as fruits of sin; as coming upon us as the result of the fall, and as an evidence that we are depraved. It is certain that there is no suffering in heaven, and that there never would be any in a perfectly holy world. It is equally certain that all the woes of earth are the consequence of man’s apostasy; and it is proper, therefore, when we are afflicted, even though we cannot trace the affliction to any “particular” offence, to trace it all to the existence of evil, and to regard it as among the proofs of the divine displeasure against sin. And my bones are consumed - That is, are decayed, worn out, or wasted away. […]
