• Matthew 12:34-37
  Brood of vipers! How can you, being evil, speak good things? For out of the abundance of the heart the mouth speaks. A good man out of the good treasure of his heart brings forth good things, and an evil man out of the evil treasure brings forth evil things. But I say to you that for every idle word men may speak, they will give account of it in the day of judgment. For by your words you will be justified, and by your words you will be condemned."
   
• James 3:1-6
  My brethren, let not many of you become teachers, knowing that we shall receive a stricter judgment. For we all stumble in many things. If anyone does not stumble in word, he is a perfect man, able also to bridle the whole body. Indeed, we put bits in horses' mouths that they may obey us, and we turn their whole body. Look also at ships: although they are so large and are driven by fierce winds, they are turned by a very small rudder wherever the pilot desires. Even so the tongue is a little member and boasts great things. See how great a forest a little fire kindles! And the tongue is a fire, a world of iniquity. The tongue is so set among our members that it defiles the whole body, and sets on fire the course of nature; and it is set on fire by hell.
   
• Proverbs 10:19
  In the multitude of words sin is not lacking,
  But he who restrains his lips is wise.
  
   
• Titus 3:1-3
  Remind them to be subject to rulers and authorities, to obey, to be ready for every good work, to speak evil of no one, to be peaceable, gentle, showing all humility to all men. For we ourselves were also once foolish, disobedient, deceived, serving various lusts and pleasures, living in malice and envy, hateful and hating one another.
   
• James 1:19
  So then, my beloved brethren, let every man be swift to hear, slow to speak, slow to wrath;
   
• Ecclesiastes 5:2-7
  Do not be rash with your mouth,
  And let not your heart utter anything hastily before God.
  For God is in heaven, and you on earth;
  Therefore let your words be few.
  For a dream comes through much activity,
  And a fool's voice is known by his many words.
  When you make a vow to God, do not delay to pay it;
  For He has no pleasure in fools.
  Pay what you have vowed—
  Better not to vow than to vow and not pay. Do not let your mouth cause your flesh to sin, nor say before the messenger of God that it was an error. Why should God be angry at your excuse and destroy the work of your hands? For in the multitude of dreams and many words there is also vanity. But fear God.
   
• Ecclesiastes 12:14
  For God will bring every work into judgment,
  Including every secret thing,
  Whether good or evil.
   
• Proverbs 17:27
  He who has knowledge spares his words,
  And a man of understanding is of a calm spirit.
