A fool uttereth all his mind: but a wise man keepeth it in till afterwards.

Jamieson-Fausset-Brown Bible Commentary

11. (Compare Pr 12:16; 16:32).

mind-or, "spirit," for anger or any ill passion which the righteous restrain.

Matthew Henry's Concise Commentary

29:11. He is a fool who tells every thing he knows, and can keep no counsel. 12. One who loves flatterers, and hearkens to slanderers, causes his servants to become liars and false accusers. 13. Some are poor, others have a great deal of deceitful riches. They meet in the business of this world; the Lord gives to both the comforts of this life. To some of both sorts he gives his grace. 14. The rich will look to themselves, but the poor and needy the prince must defend and plead for. 15. Parents must consider the benefit of due correction, and the mischief of undue indulgence. 16. Let not the righteous have their faith and hope shocked by the increase of sin and sinners, but let them wait with patience. 17. Children must not be suffered to go without rebuke when they do amiss. 18. How bare does a place look without Bibles and ministers! and what an easy prey is it to the enemy of souls! That gospel is an open vision, which holds forth Christ, which humbles the sinner and exalts the Saviour, which promotes holiness in the life and conversation: and these are precious truths to keep the soul alive, and prevent it from perishing.

Matthew Henry's Whole Bible Commentary

Verse 11

Note, 1. It is a piece of weakness to be very open: He is a fool who utters all his mind,-who tells every thing he knows, and has in his mouth instantly whatever he has in his thoughts, and can keep no counsel,-who, whatever is started in discourse, quickly shoots his bolt,-who, when he is provoked, will say any thing that comes uppermost, whoever is reflected upon by it,-who, when he is to speak of any business, will say all he thinks, and yet never thinks he says enough, whether choice or refuse, corn or chaff, pertinent or impertinent, you shall have it all. 2. It is a piece of wisdom to be upon the reserve: A wise man will not utter all his mind at once, but will take time for a second thought, or reserve the present thought for a fitter time, when it will be more pertinent and likely to answer his intention; he will not deliver himself in a continued speech, or starched discourse, but with pauses, that he may hear what is to be objected and answer it. Non minus interdum oratorium est tacere quam dicere-True oratory requires an occasional pause. Plin. Ep. 7.6.
