Charles Ellicott Commentary Proverbs 15:19

"The way of the sluggard is as a hedge of thorns; But the path of the upright is made a highway." — Proverbs 15:19 (ASV)

As a hedge of thorns.—Every difficulty in his path serves as an excuse for inaction ; while the upright man, who does his duty as in the sight of God, goes from strength to strength (Psalms 84:7), along the path of life smoothed for him (Isaiah 26:7), performing the “just works” appointed for him to do.
