Proverbs 12:15-19

The way of the [arrogant] fool [who rejects God’s wisdom] is right in his own eyes, But a wise and prudent man is he who listens to counsel. [Prov 3:7; 9:9; 21:2] The [arrogant] fool’s anger is quickly known [because he lacks self-control and common sense], But a prudent man ignores an insult. He who speaks truth [when he testifies] tells what is right, But a false witness utters deceit [in court]. There is one who speaks rashly like the thrusts of a sword, But the tongue of the wise brings healing. Truthful lips will be established forever, But a lying tongue is [credited] only for a moment.
