Proverbs 13:16

14 The law of the wise is a fountain of life, to depart from the snares of death.

15 Good understanding giveth favour: but the way of transgressors is hard.

Every prudent man dealeth with knowledge: but a fool layeth open his folly.

17 A wicked messenger falleth into mischief: but a faithful ambassador is health.

18 Poverty and shame shall be to him that refuseth instruction: but he that regardeth reproof shall be honoured.

Do read the surrounding verses too, because the context often says more than a single verse.
