Proverbs 20:17-19

Amplified Bible

¹⁷ 
Food gained by deceit is sweet to a man,
But afterward his mouth will be filled with gravel [just as sin may be sweet at first, but later its consequences bring despair].
¹⁸ 
Plans are established by counsel;
So make war [only] with wise guidance.
¹⁹ 
He who goes about as a gossip reveals secrets;
Therefore do not associate with a gossip [who talks freely or flatters].^(A)
