Albert Barnes Commentary Proverbs 29:6

"In the transgression of an evil man there is a snare; But the righteous doth sing and rejoice." — Proverbs 29:6 (ASV)

While the offense of the wicked, rising out of a confirmed habit of evil, becomes a snare for his destruction; the righteous, even if he offends, is forgiven and can still rejoice in his freedom from condemnation. The second clause is taken by some as entirely contrasted with the first; it expresses the joy of one whose conscience is void of offense, and who is in no danger of falling into the snare.
