Charles Ellicott Commentary Proverbs 11:3

"The integrity of the upright shall guide them; But the perverseness of the treacherous shall destroy them." — Proverbs 11:3 (ASV)

The perverseness of transgressors shall destroy them. —Fraudulent persons (literally, those who “cover” a matter up) pervert the truth, thereby ruining their own characters (since in time they can hardly distinguish right from wrong), and losing the favour of Almighty God.
