Colossians 3:7-8

You used to walk in these ways, in the life you once lived. But now you must also rid yourselves of all such things as these: anger, rage, malice, slander, and filthy language from your lips.

You used to walk in these ways, in the life you once lived 
Ephesians 2:1-3  As for you, you were dead in your transgressions and sins, in which you used to live when you followed the ways of this world and of the ruler of the kingdom of the air, the spirit who is now at work in those who are disobedient. All of us also lived among them at one time, gratifying the cravings of our flesh and following its desires and thoughts. Like the rest, we were by nature deserving of wrath. 
Titus 3:3  At one time we too were foolish, disobedient, deceived and enslaved by all kinds of passions and pleasures. We lived in malice and envy, being hated and hating one another.
1 Peter 4:3  For you have spent enough time in the past doing what pagans choose to do--living in debauchery, lust, drunkenness, orgies, carousing and detestable idolatry.

But now you must also rid yourselves 
Ephesians 4:22-24 You were taught, with regard to your former way of life, to put off your old self, which is being corrupted by its deceitful desires; to be made new in the attitude of your minds; and to put on the new self, created to be like God in true righteousness and holiness.

of all such things as these: anger, rage, malice, slander 
Ephesians 4:31  Get rid of all bitterness, rage and anger, brawling and slander, along with every form of malice.

and filthy language from your lips 
Ephesians 4:29  Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen.
Matthew 12:36  "But I tell you that everyone will have to give account on the day of judgment for every empty word they have spoken."
Ephesians 5:4  Nor should there be obscenity, foolish talk or coarse joking, which are out of place, but rather thanksgiving.
