Albert Barnes Commentary Proverbs 16:6

"By mercy and truth iniquity is atoned for; And by the fear of Jehovah men depart from evil." — Proverbs 16:6 (ASV)

Compare Proverbs 15:8. By mercy and truth, not by sacrifices and burnt offerings, iniquity is purged, atoned for, expiated. The teaching is the same as that of the prophets.
