| Clarke's Commentary on the Bible He that answereth a matter - This is a common case; before a man can tell out his story, another will begin his. Before a man has made his response, the other wishes to confute piecemeal, though he has had his own speech already. This is foolishness to them. They are ill-bred. There are many also that give judgment before they hear the whole of the cause, and express an opinion before they hear the state of the case. How absurd, stupid, and foolish!
Gill's Exposition of the Entire BibleHe that answereth a matter before he heareth it,.... Who is impatient, and cannot wait to hear it out, but breaks in upon the speaker before he has finished what he has to say; or is rash and precipitate, and returns an answer at once, without weighing and considering, and thoroughly understanding, what is said: it is folly and shame unto him; his answer must be a foolish one, and bring shame and confusion upon him; men should be "swift to hear", and "slow to speak", James 1:9.
Keil and Delitzsch Biblical Commentary on the Old Testament13 If one giveth an answer before he heareth, It is to him as folly and shame. The part. stands here differently from what it does at Proverbs 13:18, where it is subj., and at Proverbs 17:14, where it is pred. of a simple sentence; it is also here, along with what appertains to it in accordance with the Semitic idiom, subj. to 13b (one who answers ... is one to whom this...); but, in accordance with our idiom, it becomes a hypothetical antecedent. For "to answer" one also uses השׁיב without addition; but the original full expression is השׁיב דּבר, reddere verbum, referre dictum (cf. ענה דּבר, Jeremiah 44:20, absol. in the cogn., Proverbs 15:28); דבר one may not understand of the word to which, but of the word with which, the reply is made. היא לו comprehends the meaning: it avails to him (ducitur ei), as well as it reaches to him (est ei). In Agricola's Fnfhundert Sprchen this proverb is given thus: Wer antwortet ehe er hret, der zaiget an sein torhait und wirdt ze schanden [he who answers before he hears shows his folly, and it is to him a shame]. But that would require the word to be יבושׁ, pudefiet; (היא לו) כּלמּה means that it becomes to him a ground of merited disgrace. "כּלמּה, properly wounding, i.e., shame (like atteinte son honneur), from כּלם (cogn. הלם), to strike, hit, wound" (Fl.). Sirach (11:8) warns against such rash talking, as well as against the rudeness of interrupting others.

Jamieson-Fausset-Brown Bible Commentary13. Hasty speech evinces self-conceit, and ensures shame (Pr 26:12).
Matthew Henry's Concise Commentary18:4. The well-spring of wisdom in the heart of a believer, continually supplies words of wisdom. 5. The merits of a cause must be looked to, not the person. 6,7. What mischief bad men do to themselves by their ungoverned tongues! 8. How base are those that sow contention! and what fatal effects may be expected from small beginnings of jealousy! 9. Omissions of duty, and in duty, are fatal to the soul, as well as commissions of sin. 10,11. The Divine power, made known in and through our Lord Jesus Christ, forms a strong tower for the believer, who relies on the Lord. How deceitful the defence of the rich man, who has his portion and treasure in this world! It is a strong city and a high wall only in his own conceit; for it will fail when most in need. They will be exposed to the just wrath of that Judge whom they despised as a Saviour. 12. After the heart has been lifted up with pride, a fall comes. But honour shall be the reward of humility. 13. Eagerness, with self-conceit, will expose to shame. 14. Firmness of mind supports under many pains and trials. But when the conscience is tortured with remorse, no human fortitude can bear the misery; what then will hell be? 15. We must get knowledge, not only into our heads, but into our hearts. 16. Blessed be the Lord, who makes us welcome to come to his throne, without money and without price. May his gifts make room for him in our souls.
Matthew Henry's Whole Bible CommentaryVerse 13 See here how men often expose themselves by that very thing by which they hope to gain applause. 1. Some take a pride in being quick. They answer a matter before they hear it, hear it out, nay, as soon as they but hear of it. They think it is their honour to take up a cause suddenly; and, when they have heard one side, they think the matter so plain that they need not trouble themselves to hear the other; they are already apprized of it, and masters of all the merits of the cause. Whereas, though a ready wit is an agreeable thing to play with, it is solid judgment and sound wisdom that do business. 2. Those that take a pride in being quick commonly fall under the just reproach of being impertinent. It is folly for a man to go about to speak to a thing which he does not understand, or to pass sentence upon a matter which he is not truly and fully informed of, and has not patience to make a strict enquiry into; and, if it be folly, it is and will be shame. |
