Anger resides in the lap of fools

The discretion of a man makes him slow to anger,
And his glory is to overlook a transgression.
Proverbs 19:11

But everyone must be quick to hear, slow to speak and slow to anger; for the anger of man does not achieve the righteousness of God.
James 1:19-20

Refrain from anger and give up your rage; do not be agitated--it can only bring harm.
Psam 37:8

A man without self-control is like a city broken into and left without walls.
Proverbs 25:28

But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; against such things there is no law.

Galatians 5:22-23
