Ephesians 4:29-32

Let no harmful word come out of your mouth, but only what is beneficial for building others up according to the need, so that it gives grace to those who hear it. Do not grieve the Ruach ha-Kodesh of God, by whom you were sealed for the day of redemption. Get rid of all bitterness and rage and anger and quarreling and slander, along with all malice. Instead, be kind to one another, compassionate, forgiving each other just as God in Messiah also forgave you.
