Proverbs 19:27

25 Strike a mocker, and the simple will beware; rebuke the discerning man, and he will gain knowledge.

26 He who assaults his father or evicts his mother is a son who brings shame and disgrace.

If you cease to hear instruction, my son, you will stray from the words of knowledge.

28 A corrupt witness mocks justice, and a wicked mouth swallows iniquity.

29 Judgments are prepared for mockers, and beatings for the backs of fools.

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