By loving devotion and faithfulness iniquity is atoned for, and by the fear of the LORD one turns aside from evil.

Geneva Bible Notes Reformed

By mercy and truth iniquity is purged: and by the fear of the LORD [men] depart from evil. (d) Their upright and repenting life will be a token that their sins are forgiven.

Keil & Delitzsch Lutheran

Pro 16:6 6 By love and truth is iniquity expiated, And through the fear of Jahve one escapes from evil - literally, there comes (as the effect of it) the escaping of evil (סוּר, n. actionis, as Pro 13:19), or rather, since the evil here comes into view as to its consequences (Pro 14:27; Pro 15:24), this, that one escapes evil.

Jamieson-Fausset-Brown Reformed

By mercy and truth--that is, God's (Psa 85:10); He effects the atonement, or covering of sin; and the principles of true piety incline men to depart from evil; or, "mercy" and "truth" may be man's, indicative of the gracious tempers which work instrumentally in procuring pardon. purged--expiated (as in Lev 16:33; Isa 27:9, Hebrew).
