He that walketh with wise men shall be wise: but a companion of fools shall be {i} destroyed.

(i) As he is partaker of their wickedness, and bears with their vices, so will he be punished alike as they are.

King James Translators' Notes

destroyed: Heb. broken

Jamieson-Fausset-Brown Bible Commentary

20. The benefits of good and evil of bad society are contrasted.

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 20

Note, 1. Those that would be good must keep good company, which is an evidence for them that they would be good (men's character is known by the company they choose) and will be a means of making them good, of showing them the way and of quickening and encouraging them in it. He that would be himself wise must walk with those that are so, must choose such for his intimate acquaintance, and converse with them accordingly; must ask and receive instruction from them, and keep up pious and profitable talk with them. Miss not the discourse of the elders, for they also learned of their fathers, Ecclesiasticus 8:9. And (Ecclesiasticus 6:35), Be willing to hear every godly discourse, and let not the parables of understanding escape thee. 2. Multitudes are brought to ruin by bad company: A companion of fools shall be broken (so some), shall be known (so the Septuagint), known to be a fool; noscitur ex socio-he is known by his company. He will be like them (so some), will be made wicked (so others); it comes all to one, for all those, and those only, that make themselves wicked, will be destroyed, and those that associate with evil-doers are debauched, and so undone, and at last ascribe their death to it.
