My zeal hath consumed me. [1] The Psalmist speaks of his persecutors, by whom it is certain he had been subjected to much trouble. But although they were virulent and cruel towards him, he avows that it was not so much his own private wrongs which offended him as the violation of God's law; yea rather, that he was so consumed with grief on that account as not to be affected at all with his own individual troubles. This is an example from which much profit may be derived. We are too tender and delicate in bearing wrongs; and hence it is that if we are but touched with a finger, we are instantly inflamed with anger, whilst at the same time we are but coldly affected at the most grievous offenses committed against God. But if we are animated with the zeal that inspired the Prophet it will carry us away to another kind of sorrow, which will take entire possession of our souls.

1 - "Hath consumed me. The strong term here made use of corresponds very well with the forcible language of the preceding verse. My zeal for thy word is so great, that when I see how my enemies disregard it, I am overpowered by feelings of shame at their neglect." -- Phillips.

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.

My 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.

My 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.

(Psalm 69:9).
