Proverbs 12:17-20

He that uttereth truth showeth forth righteousness; But a false witness, deceit. There is that speaketh rashly like the piercings of a sword; But the tongue of the wise is health. The lip of truth shall be established for ever; But a lying tongue is but for a moment. Deceit is in the heart of them that devise evil; But to the counsellors of peace is joy.
