Ecclesiastes 7:9
Be not hasty in thy spirit to be angry: for anger resteth in the bosom of fools.

Ephesians 4:26
Be ye angry, and sin not: let not the sun go down upon your wrath: Neither give place to the devil. Let him that stole steal no more: but rather let him labour, working with [his] hands the thing which is good, that he may have to give to him that needeth. Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers. And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption. Let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from you, with all malice: And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you.

James 1:19
Wherefore, my beloved brethren, let every man be swift to hear, slow to speak, slow to wrath.

Job 5:2
For wrath killeth the foolish man, and envy slayeth the silly one.

Matthew 5:22
But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire. Therefore if thou bring thy gift to the altar, and there rememberest that thy brother hath ought against thee; Leave there thy gift before the altar, and go thy way; first be reconciled to thy brother, and then come and offer thy gift.

Proverbs 14:29
[He that is] slow to wrath [is] of great understanding: but [he that is] hasty of spirit exalteth folly.

Proverbs 15:1-4
A soft answer turneth away wrath: but grievous words stir up anger. The tongue of the wise useth knowledge aright:but the mouth of fools poureth out foolishness. The eyes of the LORD [are] in every place, beholding the evil and the good. A wholesome tongue [is] a tree of life: but perverseness therein [is] a breach in the spirit.

Proverbs 16:32
[He that is] slow to anger [is] better than the mighty; and he that ruleth his spirit than he that taketh a city.

Proverbs 19:11
The discretion of a man deferreth his anger; and [it is] his glory to pass over a transgression.

Proverbs 22:24
Make no friendship with an angry man; and with a furious man thou shalt not go.

Proverbs 30:32-33
If thou hast done foolishly in lifting up thyself, or if thou hast thought evil, [lay] thine hand upon thy mouth. Surely the churning of milk bringeth forth butter, and the wringing of the nose bringeth forth blood: so the forcing of wrath bringeth forth strife.

Psalms 37:8
Cease from anger, and forsake wrath: fret not thyself in any wise to do evil.

Psalms 103:8
The LORD [is] merciful and gracious, slow to anger, and plenteous in mercy.

Psalms 103:9
He will not always chide: neither will he keep [his anger] for ever.
