Top 25 Bible Verses About Taming Your Tongue (ESV)

23   Whoever keeps his mouth and his tongue
    keeps himself out of trouble.

29 Let no corrupting talk come out of your mouths, but only such as is good for building up, as fits the occasion, that it may give grace to those who hear.

15:1   A soft answer turns away wrath,
    but a harsh word stirs up anger.

26 If anyone thinks he is religious and does not bridle his tongue but deceives his heart, this person’s religion is worthless.

3   Set a guard, O LORD, over my mouth;
    keep watch over the door of my lips!

3:1 Not many of you should become teachers, my brothers, for you know that we who teach will be judged with greater strictness. 2 For we all stumble in many ways. And if anyone does not stumble in what he says, he is a perfect man, able also to bridle his whole body. 3 If we put bits into the mouths of horses so that they obey us, we guide their whole bodies as well. 4 Look at the ships also: though they are so large and are driven by strong winds, they are guided by a very small rudder wherever the will of the pilot directs. 5 So also the tongue is a small member, yet it boasts of great things.

How great a forest is set ablaze by such a small fire! 6 And the tongue is a fire, a world of unrighteousness. The tongue is set among our members, staining the whole body, setting on fire the entire course of life, and set on fire by hell. 7 For every kind of beast and bird, of reptile and sea creature, can be tamed and has been tamed by mankind, 8 but no human being can tame the tongue. It is a restless evil, full of deadly poison. 9 With it we bless our Lord and Father, and with it we curse people who are made in the likeness of God. 10 From the same mouth come blessing and cursing. My brothers, these things ought not to be so. 11 Does a spring pour forth from the same opening both fresh and salt water? 12 Can a fig tree, my brothers, bear olives, or a grapevine produce figs? Neither can a salt pond yield fresh water.

13 Who is wise and understanding among you? By his good conduct let him show his works in the meekness of wisdom. 14 But if you have bitter jealousy and selfish ambition in your hearts, do not boast and be false to the truth. 15 This is not the wisdom that comes down from above, but is earthly, unspiritual, demonic. 16 For where jealousy and selfish ambition exist, there will be disorder and every vile practice. 17 But the wisdom from above is first pure, then peaceable, gentle, open to reason, full of mercy and good fruits, impartial and sincere. 18 And a harvest of righteousness is sown in peace by those who make peace.

18   There is one whose rash words are like sword thrusts,
    but the tongue of the wise brings healing.

13   Keep your tongue from evil
    and your lips from speaking deceit.

21   Death and life are in the power of the tongue,
    and those who love it will eat its fruits.

10 For

  “Whoever desires to love life
    and see good days,
  let him keep his tongue from evil
    and his lips from speaking deceit;

28   Even a fool who keeps silent is considered wise;
    when he closes his lips, he is deemed intelligent.

4   A gentle tongue is a tree of life,
    but perverseness in it breaks the spirit.

11 it is not what goes into the mouth that defiles a person, but what comes out of the mouth; this defiles a person.”

33 “Either make the tree good and its fruit good, or make the tree bad and its fruit bad, for the tree is known by its fruit. 34 You brood of vipers! How can you speak good, when you are evil? For out of the abundance of the heart the mouth speaks. 35 The good person out of his good treasure brings forth good, and the evil person out of his evil treasure brings forth evil. 36 I tell you, on the day of judgment people will give account for every careless word they speak, 37 for by your words you will be justified, and by your words you will be condemned.”

10 From the same mouth come blessing and cursing. My brothers, these things ought not to be so.

19   When words are many, transgression is not lacking,
    but whoever restrains his lips is prudent.

2 to speak evil of no one, to avoid quarreling, to be gentle, and to show perfect courtesy toward all people.

2   Your tongue plots destruction,
    like a sharp razor, you worker of deceit.

9   Whoever covers an offense seeks love,
    but he who repeats a matter separates close friends.

14 The LORD will fight for you, and you have only to be silent.”

30   The mouth of the righteous utters wisdom,
    and his tongue speaks justice.

19 Know this, my beloved brothers: let every person be quick to hear, slow to speak, slow to anger; 20 for the anger of man does not produce the righteousness of God.

20   For lack of wood the fire goes out,
    and where there is no whisperer, quarreling ceases.

2 For we all stumble in many ways. And if anyone does not stumble in what he says, he is a perfect man, able also to bridle his whole body.
