Psalms 109:20

The Lord Jesus may speak here as a Judge, denouncing sentence on some of his enemies, to warn others. When men reject the salvation of Christ, even their prayers are numbered among their sins. See what hurries some to shameful deaths, and brings the families and estates of others to ruin; makes them and theirs despicable and hateful, and brings poverty, shame, and misery upon their posterity: it is sin, that mischievous, destructive thing. And what will be the effect of the sentence, "Go, ye cursed," upon the bodies and souls of the wicked! How it will affect the senses of the body, and the powers of the soul, with pain, anguish, horror, and despair! Think on these things, sinners, tremble and repent.

This is the summing up of the entire imprecation, and fixes it upon the persons who had so maliciously assailed the inoffensive man of God. David was a man of gentle mould, and remarkably free from the spirit of revenge, and therefore we may here conceive him to be speaking as a judge or as a representative man, in whose person great principles needed to be vindicated and great injuries redressed. Thousands of God's people are perplexed with this psalm, and we fear we have contributed very little towards their enlightenment, and perhaps the notes we have gathered from others, since they display such a variety of view, may only increase the difficulty. What then? Is it not good for us sometimes to be made to feel that we are not yet able to understand all the word and mind of God? A thorough bewilderment, so long as it does not stagger our faith, may be useful to us by confounding our pride, arousing our faculties, and leading us to cry, "What I know not teach thou me."
