Proverbs 20:18

15 Gold there is, and rubies in abundance, but lips that speak knowledge are a rare jewel. 16 Take the garment of one who puts up security for a stranger; hold it in pledge if it is done for an outsider.

17 Food gained by fraud tastes sweet, but one ends up with a mouth full of gravel. 18 Plans are established by seeking advice; so if you wage war, obtain guidance. 19 A gossip betrays a confidence; so avoid anyone who talks too much. 20 If someone curses their father or mother, their lamp will be snuffed out in pitch darkness.

21 An inheritance claimed too soon will not be blessed at the end.
