Proverbs 20:19-21

Amplified Bible

¹⁹ 
He who goes about as a gossip reveals secrets;
Therefore do not associate with a gossip [who talks freely or flatters].^(A)
20 
Whoever curses his father or his mother,
His lamp [of life] will be extinguished in time of darkness.
²¹ 
An inheritance hastily gained [by greedy, unjust means] at the beginning
Will not be blessed in the end.^(B)
