James 1:19 Wherefore, my beloved brethren, let every man be swift to hear, slow to speak, slow to wrath:
Proverbs 16:32 He that is slow to anger is better than the mighty; and he that ruleth his spirit than he that taketh a city.
James 3:2 For in many things we offend all. If any man offend not in word, the same is a perfect man, and able also to bridle the whole body.
Matthew 12:37 For by thy words thou shalt be justified, and by thy words thou shalt be condemned.
Psalm 141:3 Set a watch, O LORD, before my mouth; keep the door of my lips.
