He is in the way of life that keepeth instruction: but he that refuseth reproof erreth.

King James Translators' Notes

erreth: or, causeth to err

Jamieson-Fausset-Brown Bible Commentary

17. keepeth-observes (Pr 3:18; 4:22).

refuseth-or, "turns from reproof," which might direct him aright.

Matthew Henry's Concise Commentary

10:7. Both the just and the wicked must die; but between their souls there is a vast difference. 8. The wise in heart puts his knowledge in practice. 9. Dissemblers, after all their shuffling, will be exposed. 10. Trick and artifice will be no excuse for iniquity. 11. The good man's mouth is always open to teach, comfort, and correct others. 12. Where there is hatred, every thing stirs up strife. By bearing with each other, peace and harmony are preserved. 13. Those that foolishly go on in wicked ways, prepare rods for themselves. 14. Whatever knowledge may be useful, we must lay it up, that it may not be to seek when we want it. The wise gain this wisdom by reading, by hearing the word, by meditation, by prayer, by faith in Christ, who is made of God unto us wisdom. 15. This refers to the common mistakes both of rich and poor, as to their outward condition. Rich people's wealth exposes them to many dangers; while a poor man may live comfortably, if he is content, keeps a good conscience, and lives by faith. 16. Perhaps a righteous man has no more than what he works hard for, but that labour tends to life. 17. The traveller that has missed his way, and cannot bear to be told of it, and to be shown the right way, must err still. 18. He is especially a fool who thinks to hide anything from God; and malice is no better. 19. Those that speak much, speak much amiss. He that checks himself is a wise man, and therein consults his own peace. 20,21. The tongue of the just is sincere, freed from the dross of guile and evil design. Pious discourse is spiritual food to the needy. Fools die for want of a heart, so the word is; for want of thought.

Matthew Henry's Whole Bible Commentary

Verse 17

See here, 1. That those are in the right that do not only receive instruction, but retain it, that do not let it slip through carelessness, as most do, nor let it go to those that would rob them of it, that keep instruction safely, keep it pure and entire, keep it for their own use, that they may govern themselves by it, keep it for the benefit of others, that they may instruct them; those that do so are in the way of life, the way that has true comfort in it and eternal life at the end of it. 2. That those are in the wrong that do not only not receive instruction, but wilfully and obstinately refuse it when it is offered them. They will not be taught their duty because it discovers their faults to them; that instruction which carries reproof in it they have a particular aversion to, and certainly they err; it is a sign that they err in judgment, and have false notions of good and evil; it is a cause of their erring in conversation. The traveller that has missed his way, and cannot bear to be told of it and shown the right way, must needs err still, err endlessly; he certainly misses the way of life.
