“Be ye angry, and sin not: let not the sun go down upon your wrath:”

“Be not hasty in thy spirit to be angry: for anger resteth in the bosom of fools.”

“He that is slow to anger is better than the mighty; and he that ruleth his spirit than he that taketh a city.”

Proverbs 16:32

“Whoso keepeth his mouth and his tongue keepeth his soul from troubles.”
