Ephesians 4:29-32

Let no corrupt speech proceed out of your mouth, but such as is good for edifying as the need may be, that it may give grace to them that hear. And grieve not the Holy Spirit of God, in whom ye were sealed unto the day of redemption. Let all bitterness, and wrath, and anger, and clamor, and railing, be put away from you, with all malice: and be ye kind one to another, tenderhearted, forgiving each other, even as God also in Christ forgave you.
