James 3:1-12 King James Version (KJV)
1 My brethren, be not many masters, knowing that we shall receive the greater condemnation.
2 For in many things we offend all. If any man offend not in word, the same is a perfect man, and able also to bridle the whole body.
3 Behold, we put bits in the horses' mouths, that they may obey us; and we turn about their whole body.
4 Behold also the ships, which though they be so great, and are driven of fierce winds, yet are they turned about with a very small helm, whithersoever the governor listeth.
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.
Luke 6:45 King James Version (KJV)
45 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.
Proverbs 18:1-8 King James Version (KJV)
1 Through desire a man, having separated himself, seeketh and intermeddleth with all wisdom.
2 A fool hath no delight in understanding, but that his heart may discover itself.
3 When the wicked cometh, then cometh also contempt, and with ignominy reproach.
4 The words of a man's mouth are as deep waters, and the wellspring of wisdom as a flowing brook.
5 It is not good to accept the person of the wicked, to overthrow the righteous in judgment.
6 A fool's lips enter into contention, and his mouth calleth for strokes.
7 A fool's mouth is his destruction, and his lips are the snare of his soul.
8 The words of a talebearer are as wounds, and they go down into the innermost parts of the belly.
Ephesians 4:26-32 King James Version (KJV)
26 Be ye angry, and sin not: let not the sun go down upon your wrath:
27 Neither give place to the devil.
28 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.
29 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.
30 And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.
31 Let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from you, with all malice:
32 And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you.
Proverbs 18:20-21 King James Version (KJV)
20 A man's belly shall be satisfied with the fruit of his mouth; and with the increase of his lips shall he be filled.
21 Death and life are in the power of the tongue: and they that love it shall eat the fruit thereof.
Ephesians 4:29 King James Version (KJV)
29 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.
Galatians 6:1 King James Version (KJV)
1 Brethren, if a man be overtaken in a fault, ye which are spiritual, restore such an one in the spirit of meekness; considering thyself, lest thou also be tempted.
Proverbs 12:18 King James Version (KJV)
18 There is that speaketh like the piercings of a sword: but the tongue of the wise is health.
Proverbs 15:1-2 King James Version (KJV)
1 A soft answer turneth away wrath: but grievous words stir up anger.
2 The tongue of the wise useth knowledge aright: but the mouth of fools poureth out foolishness.
