Proverbs 20:15-18

There is gold, and an abundance of pearls, But the lips of knowledge are a vessel of preciousness [the most precious of all]. [Job 28:12, 16-19; Prov 3:15; 8:11] [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.” [Prov 27:13] 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]. Plans are established by counsel; So make war [only] with wise guidance.
