Ephesians 4:29-31

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. And do not bring sorrow to God’s Holy Spirit by the way you live. Remember, he has identified you as his own, guaranteeing that you will be saved on the day of redemption. Get rid of all bitterness, rage, anger, harsh words, and slander, as well as all types of evil behavior.
