Ephesians 4:26-29, 31-32

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. If you are a thief, quit stealing. Instead, use your hands for good hard work, and then give generously to others in need. 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.
