[Rom 12:14, 18-21 KJV] 14 Bless them which persecute you: bless, and curse not. ... 18 If it be possible, as much as lieth in you, live peaceably with all men. 19 Dearly beloved, avenge not yourselves, but [rather] give place unto wrath: for it is written, Vengeance [is] mine; I will repay, saith the Lord. 20 Therefore if thine enemy hunger, feed him; if he thirst, give him drink: for in so doing thou shalt heap coals of fire on his head. 21 Be not overcome of evil, but overcome evil with good.

[Col 3:8, 13, 19 KJV] 8 But now ye also put off all these; anger, wrath, malice, blasphemy, filthy communication out of your mouth. ... 13 Forbearing one another, and forgiving one another, if any man have a quarrel against any: even as Christ forgave you, so also [do] ye. ... 19 Husbands, love [your] wives, and be not bitter against them.

[Tit 3:2 KJV] 2 To speak evil of no man, to be no brawlers, [but] gentle, shewing all meekness unto all men.

[Jas 3:5-18 KJV] 5 Even so the tongue is a little member, and boasteth great things. Behold, how great a matter a little fire kindleth! 6 And the tongue [is] a fire, a world of iniquity: so is the tongue among our members, that it defileth the whole body, and setteth on fire the course of nature; and it is set on fire of hell. 7 For every kind of beasts, and of birds, and of serpents, and of things in the sea, is tamed, and hath been tamed of mankind: 8 But the tongue can no man tame; [it is] an unruly evil, full of deadly poison. 9 Therewith bless we God, even the Father; and therewith curse we men, which are made after the similitude of God. 10 Out of the same mouth proceedeth blessing and cursing. My brethren, these things ought not so to be. 11 Doth a fountain send forth at the same place sweet [water] and bitter? 12 Can the fig tree, my brethren, bear olive berries? either a vine, figs? so [can] no fountain both yield salt water and fresh. 13 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. 14 But if ye have bitter envying and strife in your hearts, glory not, and lie not against the truth. 15 This wisdom descendeth not from above, but [is] earthly, sensual, devilish. 16 For where envying and strife [is], there [is] confusion and every evil work. 17 But the wisdom that is from above is first pure, then peaceable, gentle, [and] easy to be intreated, full of mercy and good fruits, without partiality, and without hypocrisy. 18 And the fruit of righteousness is sown in peace of them that make peace.

[Jas 4:11 KJV] 11 Speak not evil one of another, brethren. He that speaketh evil of [his] brother, and judgeth his brother, speaketh evil of the law, and judgeth the law: but if thou judge the law, thou art not a doer of the law, but a judge.

[1Pe 2:1, 23 KJV] 1 Wherefore laying aside all malice, and all guile, and hypocrisies, and envies, and all evil speakings, ... 23 Who, when he was reviled, reviled not again; when he suffered, he threatened not; but committed [himself] to him that judgeth righteously:

[1Pe 3:9 KJV] 9 Not rendering evil for evil, or railing for railing: but contrariwise blessing; knowing that ye are thereunto called, that ye should inherit a blessing.

[1Co 13:1-13 KJV] 1 Though I speak with the tongues of men and of angels, and have not charity, I am become [as] sounding brass, or a tinkling cymbal. 2 And though I have [the gift of] prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not charity, I am nothing. 3 And though I bestow all my goods to feed [the poor], and though I give my body to be burned, and have not charity, it profiteth me nothing. 4 Charity suffereth long, [and] is kind; charity envieth not; charity vaunteth not itself, is not puffed up, 5 Doth not behave itself unseemly, seeketh not her own, is not easily provoked, thinketh no evil; 6 Rejoiceth not in iniquity, but rejoiceth in the truth; 7 Beareth all things, believeth all things, hopeth all things, endureth all things. 8 Charity never faileth: but whether [there be] prophecies, they shall fail; whether [there be] tongues, they shall cease; whether [there be] knowledge, it shall vanish away. 9 For we know in part, and we prophesy in part. 10 But when that which is perfect is come, then that which is in part shall be done away. 11 When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things. 12 For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known. 13 And now abideth faith, hope, charity, these three; but the greatest of these [is] charity.

[Eph 4:26, 32 KJV] 26 Be ye angry, and sin not: let not the sun go down upon your wrath: ... 32 And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you.

[Eph 5:1-2 KJV] 1 Be ye therefore followers of God, as dear children; 2 And walk in love, as Christ also hath loved us, and hath given himself for us an offering and a sacrifice to God for a sweetsmelling savour.

[2Co 3:12-18 KJV] 12 Seeing then that we have such hope, we use great plainness of speech: 13 And not as Moses, [which] put a vail over his face, that the children of Israel could not stedfastly look to the end of that which is abolished: 14 But their minds were blinded: for until this day remaineth the same vail untaken away in the reading of the old testament; which [vail] is done away in Christ. 15 But even unto this day, when Moses is read, the vail is upon their heart. 16 Nevertheless when it shall turn to the Lord, the vail shall be taken away. 17 Now the Lord is that Spirit: and where the Spirit of the Lord [is], there [is] liberty. 18 But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, [even] as by the Spirit of the Lord.
