(5) My foolishness.--This does not conflict with a true Messianic application of the Psalm, but is fatal to that which would see in the author not an imperfect type, but a prophetic mouthpiece of Christ.
Verses 5-12. - David follows up his complaint by a confession of sin (ver. 5), which shows that his sufferings are, at any rate, in some measure, deserved; but, at the same time, he pleads that, as his enemies are really persecuting him for his righteous deeds and his adherence to God (vers. 74 11), God is bound to come to his aid, in order that his own honour may be vindicated, and that the godly may not be put to shame on his (David's) account. Verse 5. - O God, thou knowest my foolishness (see Psalm 38:5). According to the teaching both of the Old Testament (Proverbs, passim) and of the New (Mark 7:22; Romans 1:21, 22; Galatians 3:1, etc.), folly is a form of sin. And my sins are not hid from thee. The rebuke of Nathan and the death of his child (2 Samuel 12:7-19) had fully convinced David of this. Thenceforward his sins were ever before him (Psalm 51:3), continually confessed by him, and felt to be as well known to God as to himself. Compare the opening of Psalm 139:, "Lord, thou hast searched me, and known me. Thou knowest my downsitting and mine uprising, thou understandest my thought afar off. Thou compassest my path and my lying down, and art acquainted with all my ways. For there is not a word in my tongue, but, lo, O Lord, thou knowest it altogether" (vers. 1-4).
69:1-12 We should frequently consider the person of the Sufferer here spoken of, and ask why, as well as what he suffered, that, meditating thereon, we may be more humbled for sin, and more convinced of our danger, so that we may feel more gratitude and love, constraining us to live to His glory who died for our salvation. Hence we learn, when in affliction, to commit the keeping of our souls to God, that we may not be soured with discontent, or sink into despair. David was hated wrongfully, but the words far more fully apply to Christ. In a world where unrighteousness reigns so much, we must not wonder if we meet with those that are our enemies wrongfully. Let us take care that we never do wrong; then if we receive wrong, we may the better bear it. By the satisfaction Christ made to God for our sin by his blood, he restored that which he took not away, he paid our debt, suffered for our offences. Even when we can plead Not guilty, as to men's unjust accusations, yet before God we must acknowledge ourselves to deserve all that is brought upon us. All our sins take rise from our foolishness. They are all done in God's sight. David complains of the unkindness of friends and relations. This was fulfilled in Christ, whose brethren did not believe on him, and who was forsaken by his disciples. Christ made satisfaction for us, not only by putting off the honours due to God, but by submitting to the greatest dishonours that could be done to any man. We need not be discouraged if our zeal for the truths, precepts, and worship of God, should provoke some, and cause others to mock our godly sorrow and deadness to the world.
O God, thou knowest my foolishness,.... Not that there was real foolishness in him, who, as man, from his infancy was filled with wisdom, and increased in it; and, as Mediator, had the spirit of wisdom on him, and the treasures of wisdom in him; and, as a divine Person, he is the Wisdom of God, and the only wise God; and, as in our nature, there was no foolishness in his heart, nor in his words, nor in his actions: but this is to be understood either of what was accounted so by others; he and his followers were reckoned foolish and illiterate men, and the Gospel preached by him and his apostles was foolishness to them that perished; or of what he was charged with by his enemies; even with immorality, heresy, blasphemy, and sedition; of all which he was innocent, and therefore could appeal to his divine Father, who knows all things, that he was clear of all such folly; for it may be rendered, "thou knowest as to my foolishness" (x), with respect to what he was charged with, that there was none in him; or else it regards the foolishness of his people imputed to him, the sin that folly of follies, together with all the foolishness in the heart, lip, and lives of his people, before and after conversion; these were all reckoned to him, and reckoned by him, as his own in some sense; and which is confirmed by what follows:
and my sins are not hid from thee; meaning not any committed by him; for then he could not have said what he does in Psalm 69:4; but the sins of his people imputed to him, which be calls his own; see Gill on Psalm 40:12, these must be known to his divine Father, since he is God omniscient, and since he laid them upon him, and he made satisfaction for them to him; and which he observes to enforce his petition, Psalm 69:1; with this compare Isaiah 53:11.
