(1) Judge me--i.e., do me justice, "vindicate me."

I shall not slide.--Rather, I have trusted in Jehovah without wavering.

Verse 1. - Judge me, O Lord; for I have walked in mine integrity. It seems to Christians a bold act to call on God for judgment, but the saints of the earlier dispensation, having, perhaps, a less keen sense of human imperfection, were wont to do so. It is Job's cry from his first utterance until his "words are ended;" and here we find David taking it up and re-echoing it. Man longs to hear the sentence of acquittal from the great Judge. Like Job, David asserts his "integrity," and in the same qualified sense. He is sincere in his endeavours to do right. Yet still he needs mercy and redemption (see ver. 11). I have trusted also in the Lord; therefore I shall not slide. (comp. Psalm 18:36; Psalm 37:31). David is confident of his past; for the future he trusts in God to uphold his steps, and save him from slips and falls.

26:9 David, in this psalm, appeals to God touching his integrity. - David here, by the Spirit of prophecy, speaks of himself as a type of Christ, of whom what he here says of his spotless innocence was fully and eminently true, and of Christ only, and to Him we may apply it. We are complete in him. The man that walks in his integrity, yet trusting wholly in the grace of God, is in a state of acceptance, according to the covenant of which Jesus was the Mediator, in virtue of his spotless obedience even unto death. This man desires to have his inmost soul searched and proved by the Lord. He is aware of the deceitfulness of his own heart; he desires to detect and mortify every sin; and he longs to be satisfied of his being a true believer, and to practise the holy commands of God. Great care to avoid bad company, is both a good evidence of our integrity, and a good means to keep us in it. Hypocrites and dissemblers may be found attending on God's ordinances; but it is a good sign of sincerity, if we attend upon them, as the psalmist here tells us he did, in the exercise of repentance and conscientious obedience. He feels his ground firm under him; and, as he delights in blessing the Lord with his congregations on earth, he trusts that shortly he shall join the great assembly in heaven, in singing praises to God and to the Lamb for evermore.Judge me, O Lord,.... Meaning not that God would enter into judgment with him, in respect to the justification of his person in his sight, which he knew was not by his own righteousness and integrity, but by the righteousness of God; but his view is, to the justification of his cause before men; and particularly to the difference between Saul and him; and entreats that God would interpose, take his cause in hand, judge between them, and vindicate him;

for I have walked in mine integrity; or "perfection" (o) not that he thought himself free from sin; this would be contrary to the complaints, confessions, and petitions frequently made by him; but that in the affair with which he was accused, of seeking Saul's harm, 1 Samuel 24:9; he was quite innocent: by his "integrity" he means the purity of his intentions and designs; the uprightness of his conduct, the simplicity and sincerity of his conduct towards all men, and especially his fidelity to his prince; but though he knew nothing by himself, and could not charge himself with any wrong action in this respect, and therefore ought to be acquitted before men; yet he did not expect hereby to be justified in the sight of God;

I have trusted also in the Lord; not in himself, in the sincerity of his heart, and the uprightness of his life; nor did he trust to the goodness of his cause; but he committed it to the Lord, who judgeth righteously; and trusted in him that he should not be ashamed and confounded: this shows from whence his integrity sprung, even from faith unfeigned; for, where that is true and genuine, there are works of righteousness, and integrity of life;

therefore I shall not slide; these words may be connected with the former, thus; "I have trusted also in the Lord, that I shall not slide" (p); that is, shall not fail in judgment, or lose the cause; but shall stand and carry it, and not be confounded or condemned. Our version supplies the word "therefore", making these words to be an inference from the former, that because he trusted in the Lord, therefore he should not slide, slip, and fall; not but that true believers may not only have their feet well nigh slipped, but altogether; yea, fall, and that sometimes into great sins, to the breaking of their bones; but then they shall not totally and finally fall; for they stand by faith, and are kept through it by the power of God. The words may be considered as a prayer, "let me not slide" (q); being sensible of his own weakness, and of the necessity of being upheld in his uprightness, and in the ways of the Lord by him, that his footsteps might not slip; for though he walked in his uprightness, he was not self-sufficient and self-confident, but dependent on the Lord.
