Proverbs 14:29

A patient person shows great understanding, but a quick-tempered one promotes foolishness.

Ephesians 4:26-27

Be angry and do not sin. Don’t let the sun go down on your anger, and don’t give the devil an opportunity.

James 1:19-20

My dear brothers and sisters, understand this: Everyone should be quick to listen, slow to speak, and slow to anger, for human anger does not accomplish God’s righteousness.
