Ephesians 4:29-32 NIV

[29] Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen. [30] And do not grieve the Holy Spirit of God, with whom you were sealed for the day of redemption. [31] Get rid of all bitterness, rage and anger, brawling and slander, along with every form of malice. [32] Be kind and compassionate to one another, forgiving each other, just as in Christ God forgave you.
