John Gill Bible Commentary

Judge me, O Lord my God, according to thy righteousness,.... Either that righteousness of his, by which he justifies his people, which Christ has wrought out, God has accepted of, and imputes; and which, though revealed in the Gospel, was witnessed to by the law and prophets, and was known to the saints under the Old Testament, and particularly to David; see Rom 4:6; or the perfection of his justice, his essential righteousness displayed in all his works and actions, and in the government of the world; according to this the psalmist desired to be judged; not with respect to his person before God, but with respect to his cause before men, by delivering him from his enemies, and taking vengeance on them: thus Christ also was judged according to the strict justice or righteousness of God; for as sin was righteously condemned in his flesh, being imputed to him, and found upon him; so he was, according to the justice of God, acquitted, discharged, and justified in the Spirit, when he arose from the dead; and afterwards righteous judgment was executed on his enemies the Jews, when wrath came upon them to the uttermost: and his people are also dealt with according to the righteousness of God; who acts as a righteous God, as just and faithful in forgiving their sins, on account of the blood of Christ being shed for it; and in justifying their persons by his righteousness, and by giving them the crown of righteousness laid up for them; and at last by rendering tribulation to them that have troubled them; and let them not rejoice over me; meaning his enemies, as in Psa 35:15; that is, let them not go on to rejoice; let them have no occasion for it, but deliver me out of their hands.
