25 Bible Verses About Public Speaking (ESV)

4 Now the word of the LORD came to me, saying,

5   “Before I formed you in the womb I knew you,
  and before you were born I consecrated you;
  I appointed you a prophet to the nations.”

6 Then I said, “Ah, Lord GOD! Behold, I do not know how to speak, for I am only a youth.” 7 But the LORD said to me,

  “Do not say, ‘I am only a youth’;
  for to all to whom I send you, you shall go,
  and whatever I command you, you shall speak.
8   Do not be afraid of them,
  for I am with you to deliver you,
      declares the LORD.”

9 Then the LORD put out his hand and touched my mouth. And the LORD said to me,

  “Behold, I have put my words in your mouth.
10   See, I have set you this day over nations and over kingdoms,
  to pluck up and to break down,
  to destroy and to overthrow,
  to build and to plant.”

6 Let your speech always be gracious, seasoned with salt, so that you may know how you ought to answer each person.

11 And when they bring you before the synagogues and the rulers and the authorities, do not be anxious about how you should defend yourself or what you should say, 12 for the Holy Spirit will teach you in that very hour what you ought to say.”

12 Now therefore go, and I will be with your mouth and teach you what you shall speak.”

9 So with yourselves, if with your tongue you utter speech that is not intelligible, how will anyone know what is said? For you will be speaking into the air.

11 Then the LORD said to him, “Who has made man’s mouth? Who makes him mute, or deaf, or seeing, or blind? Is it not I, the LORD?

19 and also for me, that words may be given to me in opening my mouth boldly to proclaim the mystery of the gospel, 20 for which I am an ambassador in chains, that I may declare it boldly, as I ought to speak.

8   Do not be afraid of them,
  for I am with you to deliver you,
      declares the LORD.”

19 And this is the testimony of John, when the Jews sent priests and Levites from Jerusalem to ask him, “Who are you?” 20 He confessed, and did not deny, but confessed, “I am not the Christ.” 21 And they asked him, “What then? Are you Elijah?” He said, “I am not.” “Are you the Prophet?” And he answered, “No.” 22 So they said to him, “Who are you? We need to give an answer to those who sent us. What do you say about yourself?” 23 He said, “I am the voice of one crying out in the wilderness, ‘Make straight the way of the Lord,’ as the prophet Isaiah said.”

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.

10   See, I have set you this day over nations and over kingdoms,
  to pluck up and to break down,
  to destroy and to overthrow,
  to build and to plant.”

3   Whoever guards his mouth preserves his life;
    he who opens wide his lips comes to ruin.

4 and my speech and my message were not in plausible words of wisdom, but in demonstration of the Spirit and of power, 5 so that your faith might not rest in the wisdom of men but in the power of God.

8   Oh give thanks to the LORD; call upon his name;
    make known his deeds among the peoples!

10   fear not, for I am with you;
    be not dismayed, for I am your God;
  I will strengthen you, I will help you,
    I will uphold you with my righteous right hand.

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

105:1   Oh give thanks to the LORD; call upon his name;
    make known his deeds among the peoples!

14   Let the words of my mouth and the meditation of my heart
    be acceptable in your sight,
    O LORD, my rock and my redeemer.

4 And you will say in that day:

  “Give thanks to the LORD,
    call upon his name,
  make known his deeds among the peoples,
    proclaim that his name is exalted.

19 Know this, my beloved brothers: let every person be quick to hear, slow to speak, slow to anger;

7 for God gave us a spirit not of fear but of power and love and self-control.

16 In the same way, let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven.

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.

12   The words of a wise man’s mouth win him favor,
    but the lips of a fool consume him.

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