Proverbs 12:19

17 He that speaketh truth sheweth forth righteousness: but a false witness deceit.

18 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.

20 Deceit is in the heart of them that imagine evil: but to the counsellors of peace is joy.

21 There shall no evil happen to the just: but the wicked shall be filled with mischief.

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