Ephesians 4:26-27, 29-32

And “don’t sin by letting anger control you.” Don’t let the sun go down while you are still angry, for anger gives a foothold to the devil.

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. Instead, be kind to each other, tenderhearted, forgiving one another, just as God through Christ has forgiven you.
