A soft answer turns away wrath, but a harsh word stirs up anger.
If your brother sins against you, go and tell him his fault, between you and him alone. If he listens to you, you have gained your brother. But if he does not listen, take one or two others along with you, that every charge may be established by the evidence of two or three witnesses. If he refuses to listen to them, tell it to the church. And if he refuses to listen even to the church, let him be to you as a Gentile and a tax collector.
What causes quarrels and what causes fights among you? Is it not this, that your passions are at war within you? You desire and do not have, so you murder. You covet and cannot obtain, so you fight and quarrel. You do not have, because you do not ask.
Be angry and do not sin; do not let the sun go down on your anger,
Blessed are the peacemakers, for they shall be called sons of God.
You have heard that it was said, ‘An eye for an eye and a tooth for a tooth.’ But I say to you, Do not resist the one who is evil. But if anyone slaps you on the right cheek, turn to him the other also.
1 Corinthians 13:4-7
Love is patient and kind; love does not envy or boast; it is not arrogant or rude. It does not insist on its own way; it is not irritable or resentful; it does not rejoice at wrongdoing, but rejoices with the truth. Love bears all things, believes all things, hopes all things, endures all things.
Know this, my beloved brothers: let every person be quick to hear, slow to speak, slow to anger;
Bearing with one another and, if one has a complaint against another, forgiving each other; as the Lord has forgiven you, so you also must forgive.
Repay no one evil for evil, but give thought to do what is honorable in the sight of all. If possible, so far as it depends on you, live peaceably with all. Beloved, never avenge yourselves, but leave it to the wrath of God, for it is written, “Vengeance is mine, I will repay, says the Lord.” To the contrary, “if your enemy is hungry, feed him; if he is thirsty, give him something to drink; for by so doing you will heap burning coals on his head.” Do not be overcome by evil, but overcome evil with good.
Leave your gift there before the altar and go. First be reconciled to your brother, and then come and offer your gift.
A hot-tempered man stirs up strife, but he who is slow to anger quiets contention.
If possible, so far as it depends on you, live peaceably with all.
Let all bitterness and wrath and anger and clamor and slander be put away from you, along with all malice.
Pay attention to yourselves! If your brother sins, rebuke him, and if he repents, forgive him,
The revelation of Jesus Christ, which God gave him to show to his servants the things that must soon take place. He made it known by sending his angel to his servant John,
You shall not take vengeance or bear a grudge against the sons of your own people, but you shall love your neighbor as yourself: I am the Lord.
A dishonest man spreads strife, and a whisperer separates close friends.
Know this, my beloved brothers: let every person be quick to hear, slow to speak, slow to anger; for the anger of man does not produce the righteousness of God.
When a man's ways please the Lord, he makes even his enemies to be at peace with him.
