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.
