Judge me, O Lord my God - Pronounce judgment, or judge between me and my enemies. Compare the notes at Psalms 26:1.
According to thy righteousness - That is, “rightly.” Let there be a righteous judgment. The character of God, or the righteousness of God, is the highest standard of equity and justice, and the psalmist asks that he would manifest his real character as judge in interposing in behalf of an injured and oppressed man, and doing justice to him. When we are right in our own cause we may ask a just God to interpose and determine between us and our enemies according to his own nature. As between ourselves and our fellow-men we may bring our cause with this plea before a righteous God; as between ourselves and God, we can make no appeal to his “justice,” but our only hope is in his “mercy.”
And let them not rejoice over me - Let them not carry out their purposes; let them not be successful, so that they can appeal to the result as if they were right, and thus obtain a triumph over me. Compare Psalms 35:19.
