Good understanding giveth favour: but the way of transgressors is hard.

Wesley's Notes

13:15 Giveth - Makes a man acceptable to God. Rough - Offensive and hateful to God and men, as rough ways are to a traveller.

Jamieson-Fausset-Brown Bible Commentary

15. Right perception and action secure good will, while evil ways are difficult as a stony road. The wicked left of God find punishment of sin in sinning.

hard-or, "harsh" (compare Hebrew: De 21:4; Jer 5:15).

Matthew Henry's Concise Commentary

13:14. The rule by which the wise regulate their conduct, is a fountain yielding life and happiness. 15. The way of sinners is hard upon others, and hard to the sinner himself. The service of sin is slavery; the road to hell is strewed with the thorns and thistles that followed the curse. 16. It is folly to talk of things of which we know nothing, and to undertake what we are no way fit for. 17. Those that are wicked, and false to Christ and to the souls of men, do mischief, and fall into mischief; but those that are faithful, find sound words healing to others and to themselves. 18. He that scorns to be taught, will certainly be brought down. 19. There are in man strong desires after happiness; but never let those expect any thing truly sweet to their souls, who will not be persuaded to leave their sins. 20. Multitudes are brought to ruin by bad company. And all that make themselves wicked will be destroyed. 21. When God pursues sinners he is sure to overtake them; and he will reward the righteous. 22. The servant of God who is not anxious about riches, takes the best method of providing for his children. 23. The poor, yet industrious, thrive, though in a homely manner, while those who have great riches are often brought to poverty for want of judgment. 24. He acts as if he hated his child, who, by false indulgence, permits sinful habits to gather strength, which will bring sorrow here, and misery hereafter. 25. It is the misery of the wicked, that even their sensual appetites are always craving. The righteous feeds on the word and ordinances, to the satisfying of his soul with the promises of the gospel, and the Lord Jesus Christ, who is the Bread of life.

Matthew Henry's Whole Bible Commentary

Verse 15

If we compare not only the end, but the way, we shall find that religion has the advantage; for, 1. The way of saints is pleasant and agreeable: Good understanding gains favour with God and man; our Saviour grew in that favour when he increased in wisdom. Those that conduct themselves prudently, and order their conversation aright in every thing, that serve Christ in righteousness, and peace, and joy in the Holy Ghost, are accepted of God and approved of men, Rom. 14:17, 18. And how comfortably will that man pass through the world who is well understood and is therefore well accepted! 2. The way of sinners is rough and uneasy, and, for this reason, unpleasant to themselves, because unacceptable to others. It is hard, hard upon others, who complain of it, hard to the sinner himself, who can have little enjoyment of himself while he is doing that which is disobliging to all mankind. The service of sin is perfect slavery, and the road to hell is strewed with the thorns and thistles that are the products of the curse. Sinners labour in the very fire.
