Ephesians 4:29, 31-32

Don’t use foul or abusive language. Let everything you say be good and helpful, so that your words will be an encouragement to those who hear them.

Get rid of all bitterness, rage, anger, harsh words, and slander, as well as all types of evil behavior. Instead, be kind to each other, tenderhearted, forgiving one another, just as God through Christ has forgiven you.
