Proverbs 17:27

25 A foolish son brings grief to his father and bitterness to her who bore him.

26 It is surely not good to punish the innocent or to flog a noble for his honesty.

A man of knowledge restrains his words, and a man of understanding maintains a calm spirit.

28 Even a fool is considered wise if he keeps silent, and discerning when he holds his tongue.

Do read the surrounding verses too, because the context often says more than a single verse.
