What does Ecclesiasticus Chapter 8 say, and which statements belong to its speaker?

Ecclesiasticus 8 warns against strife with powerful people lest captured, contention with rich people lest sued, and money's destructive and king-corrupting effects. Do not quarrel with the talkative or fuel their fire, or communicate with the ignorant lest family be maligned. Do not despise a person leaving sin, remembering universal need for reproof; respect old age as one's future and avoid joy at an enemy's death because all die and dislike such joy directed at themselves. Learn wise elders' discourse and proverbs for understanding, blameless service and timely answers; they learned from their fathers.

Do not provoke sinners' coals by rebuke or confront injurious people who may entrap speech. Do not lend to someone mightier, and if lending count it lost; do not guarantee above means and, if surety, expect payment. Do not judge against a judge, whom the passage says judges justly. Avoid travel with willful bold people and quarrels with passionate people, or desert travel with someone who disregards blood and may overthrow companions without help. Fools favor their own pleasures; do not deliberate before strangers whose response is unknown or open one's heart to every person lest evil and reproach return. These cautions do not say the loan is forced, silence the sole defense, or cautious conduct certain to preserve a household.
