Ephesians 4:26-27 (KJV)
26 Be ye angry, and sin not: let not the sun go down upon your wrath:
27 Neither give place to the devil.
Ephesians 4:31-32 (KJV)
31 Let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from you, with all malice:
32 And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ’s sake hath forgiven you.
