Charles Ellicott 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)

In the transgression of an evil man there is a snare. — for he does not know how by repentance to escape God’s wrath.

But the righteous doth sing and rejoice. — being assured of God’s mercy to those who repent, he rejoices because his conscience is clear, and the peace of God (Philippians 4:7) keeps his heart.
