Colossenses 3

8 But now you must rid yourselves of every kind of sin –angry and passionate outbreaks, ill-will, evil speaking, foul-mouthed abuse– so that these may never soil your lips.

9 Do not speak falsehoods to one another, for you have stripped off the old self with its doings,

10 and have clothed yourselves with the new self which is being remoulded into full knowledge so as to become like Him who created it.
