Proverbs 17:25-28

A foolish son is a grief and anguish to his father And bitterness to her who gave birth to him. It is also not good to fine the righteous, Nor to strike the noble for their uprightness. He who has knowledge restrains and is careful with his words, And a man of understanding and wisdom has a cool spirit (self-control, an even temper). [James 1:19] Even a [callous, arrogant] fool, when he keeps silent, is considered wise; When he closes his lips he is regarded as sensible (prudent, discreet) and a man of understanding.
