Thou shalt not avenge, nor bear any grudge against the children of thy people, but thou shalt love thy neighbour as thyself: I am the LORD. (Leviticus 19:18)

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. (Matthew 5:23,24)

Judge not, and ye shall not be judged: condemn not, and ye shall not be condemned: forgive, and ye shall be forgiven: (Luke 6:37)
For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again. (Matthew 7:2)

Take heed to yourselves: If thy brother trespass against thee, rebuke him; and if he repent, forgive him. And if he trespass against thee seven times in a day, and seven times in a day turn again to thee, saying, I repent; thou shalt forgive him. (Luke 17:3)

A good man out of the good treasure of his heart bringeth forth that which is good; and an evil man out of the evil treasure of his heart bringeth forth that which is evil: for of the abundance of the heart his mouth speaketh.
And why call ye me, Lord, Lord, and do not the things which I say? (Luke 6:45,46)

But I say unto you, That every idle word that men shall speak, they shall give account thereof in the day of judgment.
For by thy words thou shalt be justified, and by thy words thou shalt be condemned. (Matthew 12:36,37)

But the tongue can no man tame; it is an unruly evil, full of deadly poison.
Therewith bless we God, even the Father; and therewith curse we men, which are made after the similitude of God.
Out of the same mouth proceedeth blessing and cursing. My brethren, these things ought not so to be.
Doth a fountain send forth at the same place sweet water and bitter?
Can the fig tree, my brethren, bear olive berries? either a vine, figs? so can no fountain both yield salt water and fresh.
Who is a wise man and endued with knowledge among you? let him shew out of a good conversation his works with meekness of wisdom.
But if ye have bitter envying and strife in your hearts, glory not, and lie not against the truth.
This wisdom descendeth not from above, but is earthly, sensual, devilish.
For where envying and strife is, there is confusion and every evil work. (James 3:8-16)

But ye have not so learned Christ;
If so be that ye have heard him, and have been taught by him, as the truth is in Jesus:
That ye put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts;
And be renewed in the spirit of your mind;
And that ye put on the new man, which after God is created in righteousness and true holiness....
And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ’s sake hath forgiven you. (Ephesians 4:20-24, 32)

Let nothing be done through strife or vainglory; but in lowliness of mind let each esteem other better than themselves.
Look not every man on his own things, but every man also on the things of others.
Let this mind be in you, which was also in Christ Jesus:
Who, being in the form of God, thought it not robbery to be equal with God:
But made himself of no reputation (Philippians 2:3-7)

A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh. (Ezekiel 36:26)

Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new. (2 Corinthians 5:17)

Confess your faults one to another (James 5:16). He that covereth his sins shall not prosper: but whoso confesseth and forsaketh them shall have mercy. (Proverbs 28:13)

Lie not one to another, seeing that ye have put off the old man with his deeds; (Colossians 3:9)

For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live. (Romans 8:13)

For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders,
Thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness:
All these evil things come from within, and defile the man. (Mark 7:21-23)

Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him.
Hereby perceive we the love of God, because he laid down his life for us: and we ought to lay down our lives for the brethren.
But whoso hath this world’s good, and seeth his brother have need, and shutteth up his bowels of compassion from him, how dwelleth the love of God in him?
My little children, let us not love in word, neither in tongue; but in deed and in truth. (1 John 3:15-18)

If a man say, I love God, and hateth his brother, he is a liar: for he that loveth not his brother whom he hath seen, how can he love God whom he hath not seen? (1 John 4:20)

Take heed that ye despise not one of these little ones; for I say unto you, That in heaven their angels do always behold the face of my Father which is in heaven. (Matthew 18:10)

When the Son of man shall come in his glory, and all the holy angels with him, then shall he sit upon the throne of his glory:
And before him shall be gathered all nations: and he shall separate them one from another, as a shepherd divideth his sheep from the goats:
And he shall set the sheep on his right hand, but the goats on the left.
Then shall the King say unto them on his right hand, Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world:
For I was an hungred, and ye gave me meat: I was thirsty, and ye gave me drink: I was a stranger, and ye took me in:
Naked, and ye clothed me: I was sick, and ye visited me: I was in prison, and ye came unto me.
Then shall the righteous answer him, saying, Lord, when saw we thee an hungred, and fed thee? or thirsty, and gave thee drink?
When saw we thee a stranger, and took thee in? or naked, and clothed thee?
Or when saw we thee sick, or in prison, and came unto thee?
And the King shall answer and say unto them, Verily I say unto you, Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me.
Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels:
For I was an hungred, and ye gave me no meat: I was thirsty, and ye gave me no drink:
I was a stranger, and ye took me not in: naked, and ye clothed me not: sick, and in prison, and ye visited me not.
Then shall they also answer him, saying, Lord, when saw we thee an hungred, or athirst, or a stranger, or naked, or sick, or in prison, and did not minister unto thee?
Then shall he answer them, saying, Verily I say unto you, Inasmuch as ye did it not to one of the least of these, ye did it not to me.
And these shall go away into everlasting punishment: but the righteous into life eternal. (Matthew 25:31-46)
