Sprüche 29:8

8 Men of derision set the city in an uproar, But wise men allay anger. Isa. 28 shows what we are to understand by אנשׁי לצון: men to whom nothing is holy, and who despise all authority. The Hiphil יפיחוּ does not signify irretiunt, from פּחח (Venet. παγιδιοῦσι, after Kimchi, Aben Ezra, and others), but sufflant, from פוח (Rashi: ילהיבו): they stir up or excite the city, i.e., its inhabitants, so that they begin to burn as with flames, i.e., by the dissolution of the bonds of mutual respect and of piety, by the letting loose of passion, they disturb the peace and excite the classes of the community and individuals against each other; but the wise bring it about that the breathings of anger that has broken forth, or is in the act of breaking forth, are allayed. The anger is not that of God, as it is rendered by Jerome and Luther, and as יפיחו freely translated might mean. The Aram. err in regard to יפיחו in passages such as Pro 6:19.

See here, 1. Who are the men that are dangerous to the public - scornful men. When such are employed in the business of the state they do things with precipitation, because they scorn to deliberate, and will not take time for consideration and consultation; they do things illegal and unjustifiable, because they scorn to be hampered by laws and constitutions; they break their faith, because they scorn to be bound by their word, and provoke the people, because they scorn to please them. Thus they bring a city into a snare by their ill conduct, or (as the margin reads it) they set a city on fire; they sow discord among the citizens and run them into confusion. Those are scornful men that mock at religion, the obligations of conscience, the fears of another world, and every thing that is sacred and serious. Such men are the plagues of their generation; they bring God's judgments upon a land, set men together by the ears, and so bring all to confusion. 2. Who are the men that are the blessings of a land - the wise men who by promoting religion, which is true wisdom, turn away the wrath of God, and who, by prudent counsels, reconcile contending parties and prevent the mischievous consequences of divisions. Proud and foolish men kindle the fires which wise and good men must extinguish.
