Colossians 3:8 - But now ye also put off all these; anger, wrath, malice, blasphemy, filthy communication out of your mouth. Ephesians 4:29 - Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers. Matthew 12:36-37 - But I say unto you, That every idle word that men shall speak, they shall give account thereof in the day of judgment.
