| Barnes' Notes on the Bible My zeal hath consumed me - Margin, "cut me off." The word which is here translated "consumed" is rendered "cut off" in Lamentations 3:53; Job 23:17; Psalm 54:5; Psalm 88:16; Psalm 94:23; Psalm 101:5; Psalm 143:12; "vanish," Job 6:17; "destroyed," Psalm 73:27; 2 Samuel 22:41; Psalm 18:40; Psalm 101:8; Psalm 69:4. It means here, that he pined away; that his strength was exhausted; that he was sinking under the efforts which he had put forth as expressive of his deep interest in the cause of God and of truth. On the sentiment here expressed, see the notes at Psalm 69:9. Because mine enemies have forgotten thy words - Thy law; thy commands. It was not because they were his foes - not because he was endeavoring to destroy them, or to take vengeance on them - but because they were unmindful of God, and of the claims of his law. It is a great triumph which religion gains over a man's soul, when, in looking on the conduct of persecutors, calumniators, and slanderers - of those who are constantly doing us wrong - we are more grieved because they violate the law of God than because they injure us; when our solicitude is turned from ourselves, and terminates on our regard for the honor of God and his law. Yet that is the nature of true religion; and that we should be able to find in ourselves in such circumstances. A man should doubt the evidence of his personal religion, if all his feelings terminate on the wrong done to himself by the wicked conduct of others; if he has no feeling of solicitude because the law of God has been violated, and God has been dishonored. Compare the notes at Psalm 119:136.
Clarke's Commentary on the BibleMy zeal hath consumed me - My earnest desire to promote thy glory, and the pain I feel at seeing transgressions multiplied, have worn down both my flesh and spirits.
Gill's Exposition of the Entire BibleMy zeal hath consumed me,.... Zeal for God and his glory, for his word and ordinances and worship; which is a fervour of the mind, burning love, and flaming affections for God, shown in a holy indignation against sin and sinners. This was a zeal according to knowledge, sincere and hearty, and what continued; and which was shown in embracing and defending the truths of the word, and resenting every indignity cast upon them; to such a degree, that it ate up his spirit, wore away his flesh, and almost consumed him; see Psalm 69:9; because mine enemies have forgotten thy words; not merely through an indifference to them, and inattention in hearing them; nor through want of an earnest heed to keep and retain them; nor through negligence in laying them up, and a carelessness in making use of proper means to recollect them; but through an aversion to them, an hatred of them, and a spiteful malicious contempt of them, casting them away and despising them; which stirred up the spirit of the psalmist, and raised such an emotion in him as was almost too much for him.

Matthew Henry's Concise Commentary119:137-144 God never did, and never can do wrong to any. The promises are faithfully performed by Him that made them. Zeal against sin should constrain us to do what we can against it, at least to do more in religion ourselves. Our love to the word of God is evidence of our love to God, because it is designed to make us partake his holiness. Men's real excellency always makes them low in their own eyes. When we are small and despised, we have the more need to remember God's precepts, that we may have them to support us. The law of God is the truth, the standard of holiness, the rule of happiness; but the obedience of Christ alone justifies the believer. Sorrows are often the lot of saints in this vale of tears; they are in heaviness through manifold temptations. There are delights in the word of God, which the saints often most sweetly enjoy when in trouble and anguish. This is life eternal, to know God and Jesus Christ whom he has sent, Joh 17:3. May we live the life of faith and grace here, and be removed to the life of glory hereafter.
Matthew Henry's Whole Bible CommentaryVerse 139 Here is, 1. The great contempt which wicked men put upon religion: My enemies have forgotten thy words. They have often heard them, but so little did they heed them that they soon forgot them, they willingly forgot them, not only through carelessness let them slip out of their minds, but contrived how to cast them behind their backs. This is at the bottom of all the wickedness of the wicked, and particularly of their malignity and enmity to the people of God; they have forgotten the words of God, else those would give check to their sinful courses. 2. The great concern which godly men show for religion. David reckoned those his enemies who forgot the words of God because they were enemies to religion, which he had entered into a league with, offensive and defensive. And therefore his zeal even consumed him, when he observed their impieties. He conceived such an indignation at their wickedness as preyed upon his spirits, even ate them up (as Christ's zeal, Jn. 2:17), swallowed up all inferior considerations, and made him forget himself. My zeal has pressed or constrained me (so Dr. Hammond reads it), Acts 18:5. Zeal against sin should constrain us to do what we can against it in our places, at least to do so much the more in religion ourselves. The worse others are the better we should be. |
