30 Blows and wounds scrub away evil, and beatings purge the inmost being.
30 The blueness of a wound cleanseth
30 Blows that wound cleanse away evil; strokes make clean the innermost parts.
30 A good thrashing purges evil; punishment goes deep within us.
30 Blows that hurt cleanse away evil, As do stripes the inner depths of the heart.
30 Physical punishment cleanses away evil; such discipline purifies the heart.
Matthew Henry's Commentary on Proverbs 20:30
Commentary on Proverbs 20:30
(Read Proverbs 20:30)
Severe rebukes sometimes do a great deal of good. But such is the corruption of nature, that men are loth to be rebuked for their sins. If God uses severe afflictions, to purify our hearts and fit us for his service, we have cause to be very thankful.
