Proverbs 20:14-19

14“It is [almost] worthless, it is [almost] worthless,” says the buyer [as he negotiates the price]; But when he goes his way, then he boasts [about his bargain].

15There is gold, and an abundance of pearls, But the lips of knowledge are a vessel of preciousness [the most precious of all].

16[The judge tells the creditor], “Take the clothes of one who is surety for a stranger; And hold him in pledge [when he guarantees a loan] for foreigners.”

17Food 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].

18Plans are established by counsel; So make war [only] with wise guidance.

19He who goes about as a gossip reveals secrets; Therefore do not associate with a gossip [who talks freely or flatters].
