Proverbs 17:27

²⁷He who spares his words has knowledge. He who is even tempered is a man of understanding.

²⁷He that hath knowledge spareth his words: and a man of understanding is of an excellent spirit.

²⁷A man of knowledge restrains his words, and a man of understanding maintains a calm spirit.

²⁷If you're wise, you'll be careful what you say; and if you're sensible, you'll keep your temper.

¹⁸Now the fruit of righteousness is sown in peace by those who make peace.

¹⁹So, then, my beloved brothers, let every man be swift to hear, slow to speak, and slow to anger;

¹⁹In the multitude of words there is no lack of disobedience, but he who restrains his lips does wisely.

²⁹He who is slow to anger has great understanding, but he who has a quick temper displays folly.

²⁸The heart of the righteous weighs answers, but the mouth of the wicked gushes out evil.

²For we all stumble in many things. Anyone who doesn’t stumble in word is a perfect person, able to bridle the whole body also.

¹⁷The words of the wise heard in quiet are better than the cry of him who rules among fools.

³²One who is slow to anger is better than the mighty; one who rules his spirit, than he who takes a city.
