In your anger do not sin; when you are on your beds, search your hearts and be silent.
Better a patient man than a warrior, a man who controls his temper than one who takes a city.
Adam lay with his wife Eve, and she became pregnant and gave birth to Cain. She said, “With the help of the Lord I have brought forth a man.” Later she gave birth to his brother Abel.
Now Abel kept flocks, and Cain worked the soil. In the course of time Cain brought some of the fruits of the soil as an offering to the Lord. But Abel brought fat portions from some of the firstborn of his flock. The Lord looked with favor on Abel and his offering, but on Cain and his offering he did not look with favor. So Cain was very angry, and his face was downcast.
Then the Lord said to Cain, “Why are you angry? Why is your face downcast? If you do what is right, will you not be accepted? But if you do not do what is right, sin is crouching at your door; it desires to have you, but you must master it.”
Now Cain said to his brother Abel, “Let’s go out to the field.” And while they were in the field, Cain attacked his brother Abel and killed him.
The the Lord said to Cain, “Where is your bother Abel?”
“I don’t know,” he replied. “Am I my brother’s keeper?”
The Lord said, “What have you done? Listen! Your brother’s blood cries out to me from the ground. Now you are under a curse and driven from the ground, which opened its mouth to receive your brother’s blood from your hand. When you work the ground, it will no longer yield its crops for you. You will be a restless wanderer on the earth.”
Matthew 5: 21-26
“You have heard that it was said to the people long ago, ‘Do not murder, and anyone who murders will be subject to judgement.’ But I tell you that anyone who is angry with his brother will be subject to judgement. Again, anyone who says to his brother, ‘Raca,’ is answerable to the Sanhedrin. But anyone who says, ‘You fool!’ will be in danger of the fire of hell.
“Settle matter quickly with your adversary who is taking you to court. Do it while you are still with him on the way, or he may hand you over to the judge, and the judge may hand you over to the officer, and you may be thrown into prison. I tell you the truth, you will not get out until you have paid your last penny.”
Matthew 18: 21-35
The Peter came to Jesus and asked, “Lord, how many times shall I forgive me brother when he sins against me? Up to seven times?”
Jesus answered, “I tell you, not seven times, but seventy-seven times.
“Therefore, the kingdom of heaven is like a king who wanted to settle accounts with his servants. As he began the settlement, a man who owed him ten thousand talents was brought to him. Since he was not able to pay, the master ordered that he and his wife and his children and all that he had be sold to repay the debt.
“The servant fell on his knees before him. ‘Be patient with me,’ he begged, ‘and I will pay back everything.’ The servant’s master took pity on him, canceled the debt and let him go.
“But when that servant went out, he found one of his fellow servants who owed him a hundred denarii. He grabbed him and began to choke him. ‘Pay back what you owe me!’ he demanded.
“His fellow servant fell to his knees and begged him, ‘Be patient with me, and I will pay you back.’
“But he refused. Instead, he went off and had the man thrown into prison until he could pay the debt. When the other servants saw what had happened, they were greatly distressed and went and told their master everything that had happened.
“The the master called the servant in. ‘You wicked servant,’ he said, ‘I canceled all that debt of yours because you begged me to. Shouldn’t you have had mercy on your fellow servant just as I had on you? In anger his master turned him over to the jailers to be tortured, until he should pay back all he owed.
“This is how my heavenly Father will treat each of you unless you forgive your brother from your heart.”
Ephesians 4:26-27, 31-32
“In your anger do not sin”: Do not let the sun go down while you are still angry, and do not give the devil a foothold.
Get rid of all bitterness, rage and anger, brawling and slander, along with every form of malice. Be kind and compassionate to one another, forgiving each other, just as in Christ God forgave you.
James 1: 19-21
My dear brothers, take note of this: Everyone should be quick to listen, slow to speak and slow to become angry, for man’s anger does not bring about righteous life that God desires. Therefore, get rid of all moral filth and the evil that is so prevalent and humbly accept the word planted in you, which can save you.
