Psalms 7:8 - Ellicott's Commentary On The Whole Bible

The Lord shall. — Better, Jehovah judgeth the nations. Everything is complete, and the work of judgment begins. The poet prays that his sentence may be according to his own consciousness of righteousness and integrity. Of this plea of innocence Jerome says, “David could not say this; this properly belongs to the Saviour, who was sinless.” Others think it is the ideal Israel, which stands before Jehovah’s tribunal. But we may compare Job’s protestations of innocence, and his persistent demand for a trial. David (if he is the author) refers naturally to his innocence of the charge calumniously brought against him. As between Saul and himself, his conduct had been blameless.
