Anger makes you do stupid things
A quick-tempered man acts foolishly
Anger allows you to be manipulated by others
Like a city that is broken into and without walls is a man who has no control over his spirit.
Anger results in strife
A hot-tempered man stirs up strife, but the slow to anger calms a dispute.
Anger produces anger
A man of great anger will bear the penalty, for if you rescue him, you will only have to do it again.
Anger produces other sins
An angry man stirs up strife, and a hot-tempered man abounds in transgression.
Anger gives Satan a place or toe-hold
Do not let the sun go down on your anger, and do not give the devil an opportunity.
