The Bible does not say anger is a sin. It says "Be angry, yet do not sin," which is a more interesting instruction. God is angry in Scripture, Jesus is angry in the Gospels, and the psalms are full of righteous fury at injustice. What the Bible warns against, in dozens of verses, is the anger that is quick, that is held onto, that is vented, and that turns into contempt for another person. It treats anger as a fire: useful in the hearth, deadly in the house.

This guide gathers 25 passages under six headings: the key instruction, the Proverbs on temper, Jesus on anger, the anger of God and of Jesus, what anger does to a community, and how to deal with it. Quotations are from the Berean Standard Bible; every reference links to the chapter.

The key instruction: angry without sinning

"Be angry, yet do not sin." Do not let the sun set upon your anger, and do not give the devil a foothold.

Ephesians 4:26–27

Paul is quoting Psalm 4:4, "Be angry, yet do not sin; on your bed, search your heart and be still" (Psalm 4:4). The King James wording is the one most people know: "Be ye angry, and sin not: let not the sun go down upon your wrath" (Ephesians 4:26, KJV). Three things are packed in here. Anger is permitted. Anger has a time limit: deal with it today. And anger left overnight becomes a door for something worse.

My beloved brothers, understand this: Everyone should be quick to listen, slow to speak, and slow to anger, for man's anger does not bring about the righteousness that God desires.

James 1:19–20

James gives the order of operations: listen first, speak second, get angry last. The reason is practical: human anger does not produce the good it thinks it is fighting for. The King James has "swift to hear, slow to speak, slow to wrath" (James 1:19, KJV).

The Proverbs on temper

Proverbs has more to say about anger than any other book, and it says it in pictures.

A gentle answer turns away wrath, but a harsh word stirs up anger.

Proverbs 15:1

"A soft answer turneth away wrath" in the King James (Proverbs 15:1, KJV) is probably the most practical sentence about anger ever written. It puts the power to end an argument in the hands of the person who answers.

He who is slow to anger is better than a warrior, and he who controls his temper is greater than one who captures a city.

Proverbs 16:32

A fool vents all his anger, but a wise man holds it back.

Proverbs 29:11

This directly contradicts the modern idea that venting is healthy. Proverbs says the fool lets it all out.

Like a city whose walls are broken down is a man who does not control his temper.

Proverbs 25:28

A patient man has great understanding, but a quick-tempered man promotes folly.

Proverbs 14:29

A hot-tempered man stirs up strife, but he who is slow to anger calms dispute.

Proverbs 15:18

A man's insight gives him patience, and his virtue is to overlook an offense.

Proverbs 19:11

A fool's anger is known at once, but a prudent man overlooks an insult.

Proverbs 12:16

To start a quarrel is to release a flood; so abandon the dispute before it breaks out.

Proverbs 17:14

Do not make friends with an angry man, and do not associate with a hot-tempered man, or you may learn his ways and entangle yourself in a snare.

Proverbs 22:24–25

Ecclesiastes adds the summary: "Do not be quickly provoked in your spirit, for anger settles in the lap of a fool" (Ecclesiastes 7:9). For the positive side, see Bible verses about patience.

Jesus on anger

You have heard that it was said to the ancients, "Do not murder" and "Anyone who murders will be subject to judgment." But I tell you that anyone who is angry with his brother will be subject to judgment. Again, anyone who says to his brother, "Raca," will be subject to the Sanhedrin. But anyone who says, "You fool!" will be subject to the fire of hell.

Matthew 5:21–22

Jesus traces murder back to its root and finds anger there. "Raca" is an Aramaic insult meaning something like "empty-head," and "you fool" is worse. His point is that contempt for a person is the seed from which violence grows, and God judges the seed. He follows it immediately with a practical command:

So if you are offering your gift at the altar and there remember that your brother has something against you, leave your gift there before the altar. First go and be reconciled to your brother; then come and offer your gift.

Matthew 5:23–24

Reconciliation comes before worship. See our guide to what the Bible says about forgiveness.

The anger of God and the anger of Jesus

The Bible would be dishonest if it condemned all anger, because it attributes anger to God. But it describes God's anger in a specific way.

The LORD is compassionate and gracious, slow to anger, abounding in loving devotion.

Psalm 103:8

"Slow to anger" is part of God's own self-description to Moses in Exodus 34:6, and it is repeated throughout the Old Testament. Nahum adds the other side: "The LORD is slow to anger and great in power; the LORD will by no means leave the guilty unpunished" (Nahum 1:3). God's anger is real, slow, and just.

Jesus was angry too:

Jesus looked around at them with anger and sorrow at their hardness of heart. Then He said to the man, "Stretch out your hand." So he stretched it out, and it was restored.

Mark 3:5

He was angry that religious leaders would rather a man stay crippled than see a healing on the Sabbath. Notice what he did with the anger: he healed the man. In the temple he "overturned the tables of the money changers" and said, "you have made it 'a den of robbers'" (Mark 11:15–17). Righteous anger in the Bible is anger at injustice and hardness, directed at the wrong rather than at people, and it produces action that helps.

What anger does to a community

Get rid of all bitterness, rage and anger, outcry and slander, along with every form of malice. Be kind and tenderhearted to one another, forgiving each other just as in Christ God forgave you.

Ephesians 4:31–32

But now you must put aside all such things as these: anger, rage, malice, slander, and filthy language from your lips.

Colossians 3:8

Paul lists "hatred, discord, jealousy, and rage" among "the acts of the flesh" (Galatians 5:20), tells men to pray "without anger or dissension" (1 Timothy 2:8), and requires that a church leader be "not quick-tempered" (Titus 1:7). Fathers are told not to "provoke your children to wrath" (Ephesians 6:4). Anger, in the New Testament, is a community problem before it is a personal one.

Refrain from anger and abandon wrath; do not fret, it can only bring harm.

Psalm 37:8

Three stories about anger

Cain. The first anger in the Bible. "Why are you angry," God asked him, "and why has your countenance fallen? If you do what is right, will you not be accepted? But if you refuse to do what is right, sin is crouching at your door; it desires you, but you must master it" (Genesis 4:6–7). God does not condemn the anger. He warns that it is about to become something else, and tells Cain he can still master it. Cain did not, and his brother died.

Moses. After forty years of leading a complaining people, Moses lost his temper at the rock: "Listen now, you rebels, must we bring you water out of this rock?" He struck it twice instead of speaking to it, and God told him he would not enter the land (Numbers 20:10–12). One outburst, after a lifetime of patience, cost the meekest man on earth the thing he had walked toward for forty years.

David and Abigail. Insulted by a rich fool named Nabal, David strapped on his sword to kill every male in the household. Nabal's wife Abigail met him on the road with food and words, and David stopped: "Blessed is your discernment, and blessed are you, because today you kept me from bloodshed and from avenging myself by my own hand" (1 Samuel 25:32–33). A soft answer turned away wrath, and David spent the rest of his life grateful for it.

Jonah is the comic version: sulking under a withered plant, he is asked twice by God, "Have you any right to be angry?" and answers, "I am angry enough to die!" (Jonah 4:9). Anger, the book suggests, is often about the wrong thing entirely.

How to deal with anger, according to the Bible

  • Slow it down. James 1:19: listen, then speak, then, last of all, get angry. Most anger that is slowed down changes shape.
  • Do not vent it. Proverbs 29:11. Say what is wrong plainly; do not pour out everything you feel.
  • Give it a deadline. Ephesians 4:26: before sunset. Anger that is handled today does not become bitterness tomorrow.
  • Hand the vengeance to God. "Do not avenge yourselves, beloved, but leave room for God's wrath. … Do not be overcome by evil, but overcome evil with good" (Romans 12:19–21).
  • Go and be reconciled. Matthew 5:24. Before the next worship service, if possible.
  • Aim it. Mark 3:5. If the anger is at a real wrong, let it produce a right action rather than a wounded person.

FAQ

Is anger a sin in the Bible?

Not in itself. Ephesians 4:26 says "Be angry, yet do not sin," God is described as slow to anger, and Jesus was angry at hardness of heart. What the Bible condemns is anger that is quick, held onto, vented, or turned into contempt for a person (Matthew 5:22, Proverbs 29:11, Colossians 3:8).

What does the Bible say about controlling anger?

Proverbs 16:32 says the person who controls his temper is greater than one who captures a city, and Proverbs 29:11 says a wise man holds anger back. James 1:19 gives the method: be quick to listen and slow to speak. Ephesians 4:26 adds a time limit: settle it before sunset.

What is righteous anger?

Anger at what God is angry at: injustice, cruelty, and hardness of heart. Jesus in Mark 3:5 and in the temple is the model. Righteous anger is slow, aimed at the wrong rather than the person, and produces help rather than harm. James 1:20 warns that most human anger does not qualify.

What does "do not let the sun go down on your anger" mean?

Ephesians 4:26 tells Christians to deal with anger the same day, by resolving the matter or handing it to God, rather than carrying it to bed. Verse 27 gives the reason: anger kept overnight "gives the devil a foothold" and hardens into bitterness.

Which Bible verse is best for someone with an anger problem?

Proverbs 15:1, "A gentle answer turns away wrath," for the moment of conflict; James 1:19–20 for the pattern; and Psalm 37:8, "Refrain from anger and abandon wrath," as a daily prayer. Cain's story in Genesis 4 is worth reading for the warning that anger can be mastered before it acts.
