The wisdom of the prudent is to understand his way: but the folly of fools is deceit.

Wesley's Notes

14:8 His way - Consists not in vain speculations, but in a diligent study of his duty, and of the way to eternal happiness. The folly - The wit of ungodly men, which is really their folly, is employed only in finding out ways of deceiving.

Jamieson-Fausset-Brown Bible Commentary

8. Appearances deceive the thoughtless, but the prudent discriminate.

Matthew Henry's Concise Commentary

14:1 A woman who has no fear of God, who is wilful and wasteful, and indulges her ease, will as certainly ruin her family, as if she plucked her house down. 2. Here are grace and sin in their true colours. Those that despise God's precepts and promises, despise God and all his power and mercy. 3. Pride grows from that root of bitterness which is in the heart. The root must be plucked up, or we cannot conquer this branch. The prudent words of wise men get them out of difficulties. 4. There can be no advantage without something which, though of little moment, will affright the indolent. 5. A conscientious witness will not dare to represent anything otherwise than according to his knowledge. 6. A scorner treats Divine things with contempt. He that feels his ignorance and unworthiness will search the Scriptures in a humble spirit. 7. We discover a wicked man if there is no savour of piety in his discourse. 8. We are travellers, whose concern is, not to spy out wonders, but to get to their journey's end; to understand the rules we are to walk by, also the ends we are to walk toward. The bad man cheats himself, and goes on in his mistake. 9. Foolish and profane men consider sin a mere trifle, to be made light of rather than mourned over. Fools mock at the sin-offering; but those that make light of sin, make light of Christ. 10. We do not know what stings of conscience, or consuming passions, torment the prosperous sinner. Nor does the world know the peace of mind a serious Christian enjoys, even in poverty and sickness. 11. Sin ruins many great families; whilst righteousness often raises and strengthens even mean families. 12. The ways of carelessness, of worldliness, and of sensuality, seem right to those that walk in them; but self-deceivers prove self-destroyers. See the vanity of carnal mirth. 14. Of all sinners backsliders will have the most terror when they reflect on their own ways. 15. Eager readiness to believe what others say, has ever proved mischievous. The whole world was thus ruined at first. The man who is spiritually wise, depends on the Saviour alone for acceptance. He is watchful against the enemies of his salvation, by taking heed to God's word. 16. Holy fear guards against every thing unholy. 17. An angry man is to be pitied as well as blamed; but the revengeful is more hateful.
