They won't stop trying to ruin you, and you want someone to finally judge who's in the right.
When your enemies keep on, trying to drag you down and ruin you, don't let any human verdict be the last word, because everything human is open to doubt. Ask God to be the Judge, for He alone is just, and say Psalms 26, 35 and 43.
Letter to Marcellinus
Leaving the verdict with God doesn't mean staying silent: Paul himself appealed to Caesar (Acts 25:11).
