'Quick tempered' in the Bible

A quick-tempered man acts foolishly,And a man of evil devices is hated.

He who is slow to anger has great understanding,But he who is quick-tempered exalts folly.

For the overseer must be above reproach as God’s steward, not self-willed, not quick-tempered, not addicted to wine, not pugnacious, not fond of sordid gain,
