Matthew Henry commentary on Proverbs 13:13-17
Embedded KJV/source Scripture
15 Good understanding giveth favour: but the way of transgressors is hard.
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. xiv. 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.

16 Every prudent man dealeth with knowledge: but a fool layeth open his folly.
Note, 1. It is wisdom to be cautious. Every prudent discreet man does all with knowledge (considering with himself and consulting with others), acts with deliberation and is upon the reserve, is careful not to meddle with that which he has not some knowledge of, not to launch out into business which he has not acquainted himself with, will not deal with those that he has not some knowledge of, whether they may be confided in. He is still dealing in knowledge, that he may increase the stock he has. 2. It is folly to be rash, as the fool is, who is forward to talk of things he knows nothing of and undertake that which he is no way fit for, and so lays open his folly and makes himself ridiculous. He began to build and was not able to finish.

17 A wicked messenger falleth into mischief: but a faithful ambassador is health.
Here we have, 1. The ill consequences of betraying a trust. A wicked messenger, who, being sent to negotiate any business, is false to him that employed him, divulges his counsels, and so defeats his designs, cannot expect to prosper, but will certainly fall into some mischief or other, will be discovered and punished, since nothing is more hateful to God and man than the treachery of those that have a confidence reposed in them. 2. The happy effects of fidelity: An ambassador who faithfully discharges his trust, and serves the interests of those who employ him, is health; he is health to those by whom and for whom he is employed, heals differences that are between them, and preserves a good understanding; he is health to himself, for he secures his own interest. This is applicable to ministers, Christ's messengers and ambassadors; those that are wicked and false to Christ and the souls of men do mischief and fall into mischief, but those that are faithful will find sound words to be healing words to others and themselves.

18 Poverty and shame shall be to him that refuseth instruction: but he that regardeth reproof shall be honoured.
Note, 1. He that is so proud that he scorns to be taught will certainly be abased. He that refuses the good instruction offered him, as if it were a reflection upon his honour and an abridgment of his liberty, poverty and shame shall be to him: he will become a beggar and live and die in disgrace; every one will despise him as foolish, and stubborn, and ungovernable. 2. He that is so humble that he takes it well to be told of his faults shall certainly be exalted: He that regards a reproof, whoever gives it to him, and will mend what is amiss when it is shown him, gains respect as wise and candid; he avoids that which would be a disgrace to him and is in a fair way to make himself considerable.

19 The desire accomplished is sweet to the soul: but it is abomination to fools to depart from evil.
This shows the folly of those that refuse instruction, for they might be happy and will not. 1. They might be happy. There are in man strong desires of happiness; God has provided for the accomplishment of those desires, and that would be sweet to the soul, whereas the pleasures of sense are grateful only to the carnal appetite. The desire of good men towards the favour of God and spiritual blessings brings that which is sweet to their souls; we know those that can say so by experience, Ps. iv. 6, 7 . 2. Yet they will not be happy; for it is an abomination to them to depart from evil, which is necessary to their being happy. Never let those expect any thing truly sweet to their souls that will not be persuaded to leave their sins, but that roll them under their tongues as a sweet morsel.
