Proverbs 12:18-20 American Standard Version (ASV)

18. There is that speaketh rashly like the piercings of a sword; But the tongue of the wise is health.

19. The lip of truth shall be established for ever; But a lying tongue is but for a moment.

20. Deceit is in the heart of them that devise evil; But to the counsellors of peace is joy.
