Ephesians 4:29-32
No foul language should come out of your mouths, but only such as is good for needed edification, that it may impart grace to those who hear. And do not grieve the holy Spirit of God, with which you were sealed for the day of redemption. All bitterness, fury, anger, shouting, and reviling must be removed from you, along with all malice. And be kind to one another, compassionate, forgiving one another as God has forgiven you in Christ.
