Verse 11. - But as for me, I will walk in mine integrity; i.e. I will continue to walk as I have walked hitherto (see ver. 1) - I will be "integer vitae scelerisque purus" - a brave and good resolve. Had he but kept to it! Redeem me, and be merciful unto me (compare the comment on ver. 1). Though hitherto he has walked innocently, and is resolved still to continue to walk innocently; he nevertheless feels that he has need of redeeming mercy. Though he "knows nothing by himself, yet he is not thereby justified" (1 Corinthians 4:4). Many, doubtless, are his "secret sins," which God has "set in the light of his countenance" (Psalm 90:8).

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.But as for me, I will walk in mine integrity,.... In which he had hitherto walked, Psalm 26:1; or it may express his faith, that after he was gathered by death he should walk in uprightness and righteousness, in purity and perfection, with Christ in white, and behold the face of God in righteousness; see Isaiah 57:1;

redeem me; from the vain conversation of the wicked, from all troubles, and out of the hands of all enemies;

and be merciful unto me; who was now in distress, being persecuted by Saul, and at a distance from the house of God: this shows that mercy is the source and spring of redemption, both temporal and spiritual; and that the psalmist did not trust in and depend upon his present upright walk and conversation, but in redemption by Christ, and upon the mercy of God in Christ.
