• James 3:8-12
  But no man can tame the tongue. It is an unruly evil, full of deadly poison. With it we bless our God and Father, and with it we curse men, who have been made in the similitude of God. Out of the same mouth proceed blessing and cursing. My brethren, these things ought not to be so. Does a spring send forth fresh water and bitter from the same opening? Can a fig tree, my brethren, bear olives, or a grapevine bear figs? Thus no spring yields both salt water and fresh.

• Proverbs 25:11

  In settings of silver.
  
   
• Proverbs 27:17
  As iron sharpens iron,

• Matthew 12:34
  Brood of vipers! How can you, being evil, speak good things? For out of the abundance of the heart the mouth speaks.
   
• Hebrews 3:12-13
  Beware, brethren, lest there be in any of you an evil heart of unbelief in departing from the living God; but exhort one another daily, while it is called "Today," lest any of you be hardened through the deceitfulness of sin.
   
• 1 Kings 22:20-22
  And the LORD said, ‘Who will persuade Ahab to go up, that he may fall at Ramoth Gilead?’ So one spoke in this manner, and another spoke in that manner. Then a spirit came forward and stood before the LORD, and said, ‘I will persuade him.’ The LORD said to him, ‘In what way?’ So he said, ‘I will go out and be a lying spirit in the mouth of all his prophets.’ And the LORD said, ‘You shall persuade him, and also prevail. Go out and do so.’

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

  And you He made alive, who were dead in trespasses and sins, in which you once walked according to the course of this world, according to the prince of the power of the air, the spirit who now works in the sons of disobedience, among whom also we all once conducted ourselves in the lusts of our flesh, fulfilling the desires of the flesh and of the mind, and were by nature children of wrath, just as the others.

• Romans 10:14-17
  How then shall they call on Him in whom they have not believed? And how shall they believe in Him of whom they have not heard? And how shall they hear without a preacher? And how shall they preach unless they are sent? As it is written:
  "How beautiful are the feet of those who preach the gospel of peace,
  Who bring glad tidings of good things!" But they have not all obeyed the gospel. For Isaiah says, "LORD, who has believed our report?" So then faith comes by hearing, and hearing by the word of God.
