What does Proverbs Chapter 29 say, and which statements belong to its speaker?

Proverbs 29 says obstinate rejection of reproof brings sudden destruction without following health; it does not pronounce repentance metaphysically impossible. Increasing just people brings popular joy, wicked rule mourning. Wisdom gladdens a father, maintaining harlots wastes substance. A just king strengthens land, a covetous man destroys it. Flattery spreads a net; wicked sin entangles, the just shall praise and rejoice. The just knows the poor’s cause, the wicked lacks knowledge. Corrupt men ruin a city, wise men turn wrath away. A wise man’s contention with a fool has no rest whether he is angry or laughing; the ambiguous pronoun is not silently resolved. Bloodthirsty men hate the upright, the just seek his soul. A fool exposes all his mind, the wise defers and reserves it. A prince glad to hear lies has wicked servants. The poor man and creditor meet, and the Lord enlightens both. A king judging the poor truly has a throne established forever, as the passage asserts.

Rod and reproof give wisdom, a child left to own will shames a mother. With multiplying wickedness crimes multiply; the just shall see their downfall. Instruct a son for refreshment and delight. When prophecy fails people scatter; law-keeping is blessed. Words cannot correct a slave who understands without answering. Hasty speech promises folly rather than amendment. A servant delicately brought up shall grow stubborn. Passion stirs quarrels, anger inclines to sin. Pride humbles, a humble spirit shall gain glory. A thief’s partner hates his soul, hears an oath and fails to disclose. Fear of man soon brings a fall, Lord-trusting shall be lifted high. Many seek a prince’s face, each man’s judgment is from the Lord. Just and wicked abhor one another; a son keeping the word shall be free from destruction.
