Ephesians 4:29-31

4:29 You must let no unwholesome word come out of your mouth, but only what is beneficial for the building up of the one in need, that it may give grace to those who hear. 4:30 And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption. 4:31 You must put away every kind of bitterness, anger, wrath, quarreling, and evil, slanderous talk.
