Proverbs 20:19

17 Food gained by fraud is sweet to a man, but later his mouth is full of gravel.

18 Set plans by consultation, and wage war under sound guidance.

He who reveals secrets is a constant gossip; avoid the one who babbles with his lips.

20 Whoever curses his father or mother, his lamp will be extinguished in deepest darkness.

21 An inheritance gained quickly will not be blessed in the end.

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