Proverbs 20:14-19

14"Bad, bad," says the buyer, but when he goes away, then he boasts.

15There is gold and abundance of costly stones, but the lips of knowledge are a precious jewel.

16Take a man's garment when he has put up security for a stranger, and hold it in pledge when he puts up security for foreigners.

17Bread gained by deceit is sweet to a man, but afterward his mouth will be full of gravel.

18Plans are established by counsel; by wise guidance wage war.

19Whoever goes about slandering reveals secrets; therefore do not associate with a simple babbler.
