Better, He shall kiss lips that giveth a right answer, i. e., he shall gain the hearts of men as much as by all outward signs of sympathy and favor. Compare 2 Samuel 15:1-6.

Kiss his lips - Shall treat him with affection and respect.

Every man shall kiss his lips that giveth a right answer. Either as a witness to a question put to him in court, to which he answers aptly and uprightly; or rather as a judge, who, having heard a cause, answers and gives his opinion of it faithfully, and pronounces a righteous sentence; everyone will love and respect him, and hearken to him and obey him; both affection and obedience are signified by a kiss; see Psalm 2:12.

Then follows a distich with the watchword נצחים:

26 He kisseth the lips

     Who for the end giveth a right answer.

The lxx, Syr., and Targ. translate: one kisseth the lips who, or: of those who...; but such a meaning is violently forced into the word (in that case the expression would have been שׂפתי משׁיב or שׂפתים משׁיבים). Equally impossible is Theodotion's χείλεσι καταφιληθήσεται, for ישּׁק cannot be the fut. Niph. Nor is it: lips kiss him who... (Rashi); for, to be thus understood, the word ought to have been למשׁיב. משׁיב is naturally to be taken as the subj., and thus it supplies the meaning: he who kisseth the lips giveth an excellent answer, viz., the lips of him whom the answer concerns (Jerome, Venet., Luther). But Hitzig ingeniously, "the words reach from the lips of the speaker to the ears of the hearer, and thus he kisses his ear with his lips." But since to kiss the ear is not a custom, not even with the Florentines, then a welcome answer, if its impression is to be compared to a kiss, is compared to a kiss on the lips. Hitzig himself translates: he commends himself with the lips who...; but נשׁק may mean to join oneself, Genesis 41:40, as kissing is equivalent to the joining of the lips; it does not mean intrans. to cringe. Rather the explanation: he who joins the lips together...; for he, viz., before reflecting, closed his lips together (suggested by Meri); but נשׁק, with שׂפתים, brings the idea of kissing, labra labris jungere, far nearer. This prevails against Schultens' armatus est (erit) labia, besides נשׁק, certainly, from the primary idea of connecting (laying together) (vid., Psalm 78:9), to equip (arm) oneself therewith; but the meaning arising from thence: with the lips he arms himself... is direct nonsense. Fleischer is essentially right, Labra osculatur (i.e., quasi osculum oblatum reddit) qui congrua respondet. Only the question has nothing to do with a kiss; but if he who asks receives a satisfactory answer, an enlightening counsel, he experiences it as if he received a kiss. The Midrash incorrectly remarks under דּברים נצחים, "words of merited denunciation," according to which the Syr. translates. Words are meant which are corresponding to the matter and the circumstances, and suitable for the end (cf. Proverbs 8:9). Such words are like as if the lips of the inquirer received a kiss from the lips of the answerer.

Every man shall kiss his lips that giveth a right answer.

24:26 Shall kiss - Shall respect him. A right answer - That speaks pertinently and plainly, and truly.

that...: Heb. that answereth right words

26. kiss his lips-love and obey, do homage (Ps 2:12; So 8:1).

right answer-literally, "plain words" (compare Pr 8:9), opposed to deceptive, or obscure.

24:17,18. The pleasure we are apt to take in the troubles of an enemy is forbidden. 19,20. Envy not the wicked their prosperity; be sure there is no true happiness in it. 21,22. The godly in the land, will be quiet in the land. There may be cause to change for the better, but have nothing to do with them that are given change. 23-26. The wisdom God giveth, renders a man fit for his station. Every one who finds the benefit of the right answer, will be attached to him that gave it. 27. We must prefer necessaries before conveniences, and not go in debt.
