Matthew Henry's Concise Commentary

16:12. The ruler that uses his power aright, will find that to be his best security. 13. Put those in power who know how to speak to the purpose. 14,15. Those are fools, who, to obtain the favour of an earthly prince, throw themselves out of God's favour. 16. There is joy and satisfaction of spirit, only in getting wisdom. 17. A sincerely religious man keeps at a distance from every appearance of evil. Happy is the man that walks in Christ, and is led by the Spirit of Christ. 18. When men defy God's judgments, and think themselves far from them, it is a sign they are at the door. Let us not fear the pride of others, but fear pride in ourselves. 19. Humility, though it exposes to contempt in the world, is much better than high-spiritedness, which makes God an enemy. He that understands God's word shall find good. 21. The man whose wisdom dwells in his heart, will be found more truly prudent than many who possess shining talents. 22. As waters to a thirsty land, so is a wise man to his friends and neighbours. 23. The wise man's self-knowledge, always suggests something proper to be spoken to others. 24. The word of God cures the diseases that weaken our souls. 25. This is caution to all, to take heed of deceiving themselves as to their souls. 26. We must labour for the meat which endureth to everlasting life, or we must perish.

Pulpit Commentary

Verse 23. - The heart of the wise teacheth his mouth. Out of the abundance of his heart the wise man speaks; the spirit within him finds fit utterance. Pectus est quod disertos facit. The thought and mind control the outward expression and make it eloquent and persuasive (comp. Proverbs 15:2). And addeth learning to his lips; Vulgate, "addeth grace." But lekach, which means properly "reception," "taking in," is best rendered "learning," as in ver. 21; Proverbs 1:5, etc. The intellect and knowledge of the wise display themselves in their discourse. Delitzsch, "Learning mounteth up to his lips." Ecclus. 21:26, "The heart of fools is in their mouth; but the mouth of the wise is in their heart." Septuagint, "The heart of the wise will consider what proceedeth from his mouth; and on his lips he will carry prudence (ἐπιγνωμοσύνην)."

Gill's Exposition of the Entire Bible

The heart of the wise teacheth his mouth,.... That is, a man that is wise in heart, as in Proverbs 16:21; his heart will teach his mouth what to say, when to say it, and before whom; it will prompt him to matter, that he shall not be at a loss what to say, nor how to say; it will furnish him with words and things; out of the abundance of the heart the mouth speaketh, Matthew 12:34;

and addeth learning to his lips: so that he does not deliver out mere words, but solid learning along with them, instructive to himself and others. The Targum is,

"and by his lips he addeth doctrine;''

or increases knowledge.

Jamieson-Fausset-Brown Bible Commentary

23. The heart is the source of wisdom flowing from the mouth.
