Psalm 37:8 Refrain from anger, and forsake wrath. Do not fret—it leads only to evil.
Genesis 4:3-7 In the course of time Cain brought to the Lord an offering of the fruit of the ground, and Abel for his part brought of the firstlings of his flock, their fat portions. And the Lord had regard for Abel and his offering, but for Cain and his offering he had no regard. So Cain was very angry, and his countenance fell. The Lord said to Cain, ‘Why are you angry, and why has your countenance fallen? If you do well, will you not be accepted? And if you do not do well, sin is lurking at the door; its desire is for you, but you must master it.’
Matthew 5:21-26 You have heard that it was said to those of ancient times, “You shall not murder”; and “whoever murders shall be liable to judgement.” But I say to you that if you are angry with a brother or sister, you will be liable to judgement; and if you insult a brother or sister, you will be liable to the council; and if you say, “You fool”, you will be liable to the hell of fire. So when you are offering your gift at the altar, if you remember that your brother or sister has something against you, leave your gift there before the altar and go; first be reconciled to your brother or sister, and then come and offer your gift. Come to terms quickly with your accuser while you are on the way to court with him, or your accuser may hand you over to the judge, and the judge to the guard, and you will be thrown into prison. Truly I tell you, you will never get out until you have paid the last penny.
