Proverbs 12:16-18

Amplified Bible

¹⁶ 
The [arrogant] fool’s anger is quickly known [because he lacks self-control and common sense],
But a prudent man ignores an insult.
¹⁷ 
He who speaks truth [when he testifies] tells what is right,
But a false witness utters deceit [in court].
¹⁸ 
There is one who speaks rashly like the thrusts of a sword,
But the tongue of the wise brings healing.
