Ephesians 4:25-27, 30-32

Wherefore, putting away falsehood, speak ye truth each one with his neighbor: for we are members one of another. Be ye angry, and sin not: let not the sun go down upon your wrath: neither give place to the devil.

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.
