Colossians 3:8
But now ye also put off all these; anger, wrath, malice, blasphemy, filthy communication out of your mouth.
Put off anger, fierce anger, grudge.... Don't have people you are not in talking terms with.
Don't blasphem.
Don't talk nonsense. Say what is right at all times.
Wrong words, dirty and filthy communications should not come out of your mouth.
