Proverbs 12:17-20

He that speaketh truth sheweth forth righteousness: But a false witness deceit. There is that speaketh 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 imagine evil: But to the counsellors of peace is joy.
