John Trapp on Psalms 94:15

Verſ. 15. But judgement ſhall return unto Righteouſneſs] All ſhall be ſet to rights, and every one have his due, according to Rom. 2.6, 7, 8, 9, 10. if not ſooner, yet at the day of judgement without fail. Some give this ſenſe, ſeverity ſhall be changed into mercy, the rigour of the law to the clemency of the Goſpel. Others thus, judgement ſhall return to Righteouſneſs, that is, to its own place; licet defertur judicium non aufertur.

And all the upright in heart ſhall follow it] viz. In their affections; they are carried out after it, earneſtly deſiring that dear day when God will unriddle his providences, and clear up his proceedings with the ſons of men. Some read, ſhall follow him, that is, God; being brought home to him by their afflictions, they ſhall follow the Lamb whitherſoever he goeth. Not ſo every looſe ungirt Chriſtian or profligate profeſſor.
