Proverbs
A soft answer turneth away wrath: but grievous words stir up anger.
He that is slow to anger is better than the mighty; and he that ruleth his spirit than he that taketh a city.
A fool uttereth all his mind: but a wise man keepeth it in till afterwards.
Ephesians
Be ye angry, and sin not: let not the sun go down upon your wrath:
Let all bitterness, and wrath, and anger, and clamor, and evil speaking, be put away from you, with all malice:
Colossians
But now ye also put off all these; anger, wrath, malice, blasphemy, filthy communication out of your mouth.
