Proverbs 20:14-19

14“It’s worthless, it’s worthless!” the buyer says, but after he is on his way, he gloats.

15There is gold and a multitude of jewels, but knowledgeable lips are a rare treasure.

16Take his garment, for he has put up security for a stranger; get collateral if it is for foreigners.

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

18Finalize plans with counsel, and wage war with sound guidance.

19The one who reveals secrets is a constant gossip; avoid someone with a big mouth.
