Psalms 119:121

"I have dealt judgment and righteousness; O give me not over unto mine oppressors" (ver. 121). It is not wonderful that he should have dealt judgment and righteousness, since he had above prayed for a chaste fear from God, whereby to fix with nails his flesh, that is, his carnal lusts, which are wont to hinder our judgment from being right. But although in our customary speech judgment is either right or wrong, whence it is said unto men in the Gospel, "Judge not according to the persons, but judge righteous judgment:" nevertheless in this passage judgment is used as though, if it were not righteous, it ought not to be called judgment; otherwise it would not be enough to say, "I have dealt judgment," but it would be said, I have dealt righteous judgment. ... Whoso therefore in the chaste fear of God hath his flesh crucified, and corrupted by no carnal allurement, dealeth judgment and the work of righteousness, ought to pray that he may not be given up to his adversaries; that is, that he may not, through his dread of suffering evils, yield unto his adversaries to do evil. For he receiveth power of endurance, which guardeth him from being overcome with pain, from Him from whom he receiveth the victory over lust, which preventeth his being seduced by pleasure.

"I have done judgment and justice." This was a great thing for an Eastern ruler to say at any time, for these despots mostly cared more for gain than justice. Some of them altogether neglected their duty, and would not even do judgment at all, preferring their pleasures to their duties; and many more of them sold their judgments to the highest bidders by taking bribes, or regarding the persons of men. Some rulers gave neither judgment nor justice, others gave judgment without justice, but David gave judgment and justice, and saw that his sentences were carried out.

On the grounds of his integrity, desire for God's word, and covenant relation to Him, the servant of God may plead for His protecting care against the wicked, gracious guidance to the knowledge of truth, and His effective vindication of the righteous and their cause, which is also His own.

Some rulers gave neither judgment nor justice, others gave judgment without justice, but David gave judgment and justice, and saw that his sentences were carried out. He could claim before the Lord that he had dealt out even handed justice, and was doing so still. On this fact he founded a plea with which he backed the prayer—"Leave me not to mine oppressors." He who, as far as his power goes, has been doing right, may hope to be delivered from his superiors when attempts are made by them to do him wrong. If I will not oppress others, I may hopefully pray that others may not oppress me. A course of upright conduct is one which gives us boldness in appealing to the Great Judge for deliverance from the injustice of others. Nor is this kind of pleading to be censured as self righteous: when we are dealing with God as to our shortcomings, we use a very different tone from that with which we face the censures of our fellow men; when they are in the question, and we are guiltless towards them, we are justified in pleading our innocence.

I have done judgment and justice - I have given the best decision possible on every case that came before me; and I have endeavored to render to all their due.
