"Death and life are in the power of the tongue" (Proverbs 18:21). James warns that "the tongue is a little member, and boasteth great things" (James 3:5). David prayed, "Set a watch, O LORD, before my mouth; keep the door of my lips" (Psalm 141:3), and Paul says, "Let your speech be alway with grace, seasoned with salt" (Colossians 4:6).
Words are small, but they rarely stay small. One sentence can heal a friendship or end it, and one comment at a family dinner can set the tone for the whole evening. The Bible takes the tongue seriously: it holds power over life and death, it needs a guard, and it reveals what is in the heart. These twelve King James verses cover the power of words, keeping watch over your mouth, and trading gossip for gracious speech. For honesty in particular, see lying; for words that build up, see encouraging others.
Life and death in the power of the tongue
1. Proverbs 18:21
"Death and life are in the power of the tongue: and they that love it shall eat the fruit thereof."
Death and life are in the power of the tongue. Words can wound or heal, crush or revive. And they that love it shall eat the fruit thereof: we live with the harvest of what we say, good or bad.
2. James 3:5
"Even so the tongue is a little member, and boasteth great things. Behold, how great a matter a little fire kindleth!"
James compares the tongue to a spark: Behold, how great a matter a little fire kindleth! A careless rumor or angry text can spread like a wildfire long after the moment has passed.
3. James 3:9-10
"Therewith bless we God, even the Father; and therewith curse we men, which are made after the similitude of God. Out of the same mouth proceedeth blessing and cursing. My brethren, these things ought not so to be."
With the same mouth we bless God and curse people who are made after the similitude of God. James simply says, these things ought not so to be. How we talk about people is how we treat the image of God in them.
4. Matthew 12:34
"O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh."
Out of the abundance of the heart the mouth speaketh. Jesus traces our words back to their source. Taming the tongue starts with letting God change the heart; see guard your heart.
Set a watch before my mouth
5. Psalms 141:3
"Set a watch, O LORD, before my mouth; keep the door of my lips."
Set a watch, O LORD, before my mouth; keep the door of my lips. David asks God to post a guard at the door. It is a wise prayer before a meeting, a hard conversation or a holiday dinner.
6. Proverbs 21:23
"Whoso keepeth his mouth and his tongue keepeth his soul from troubles."
Whoso keepeth his mouth and his tongue keepeth his soul from troubles. Many of our troubles are self-inflicted with words. A closed mouth at the right moment saves a great deal of grief.
7. Proverbs 10:19
"In the multitude of words there wanteth not sin: but he that refraineth his lips is wise."
In the multitude of words there wanteth not sin. The more we talk, the more likely we are to say something wrong. He that refraineth his lips is wise: silence is sometimes the most godly answer.
8. James 1:19
"Wherefore, my beloved brethren, let every man be swift to hear, slow to speak, slow to wrath:"
Swift to hear, slow to speak, slow to wrath. Listening first slows the tongue down and cools anger. If you memorize only one verse before a family gathering, this may be the one.
No gossip, only gracious words
9. Proverbs 16:28
"A froward man soweth strife: and a whisperer separateth chief friends."
A whisperer separateth chief friends. Gossip does not only hurt reputations; it breaks the closest friendships. Before passing on a story, ask whether you would say it with that person standing next to you.
10. Proverbs 26:20
"Where no wood is, there the fire goeth out: so where there is no talebearer, the strife ceaseth."
Where no wood is, there the fire goeth out: so where there is no talebearer, the strife ceaseth. You do not have to win a feud to end it; you can simply stop adding wood.
11. Proverbs 15:4
"A wholesome tongue is a tree of life: but perverseness therein is a breach in the spirit."
A wholesome tongue is a tree of life. Healthy words help people flourish like a fruitful tree, while twisted words break the spirit. Ask God to make your speech a place where others can grow.
12. Colossians 4:6
"Let your speech be alway with grace, seasoned with salt, that ye may know how ye ought to answer every man."
Let your speech be alway with grace, seasoned with salt. Salt adds flavor and preserves; gracious words make truth appealing and keep conversations from going bad. Paul ties it to answering everyone well, including people outside the faith.
A short prayer
Lord, set a watch before my mouth. Forgive the careless, harsh and gossiping words I have spoken. Change my heart so that what overflows is grace. Make me quick to listen, slow to speak, and ready with a word that gives life, and let the words of my mouth please You. In Jesus' name, amen.

Frequently asked questions
What does the Bible say about the power of the tongue?
Proverbs 18:21 says "Death and life are in the power of the tongue." James 3 compares the tongue to a horse's bit, a ship's rudder and a spark that sets a forest ablaze (James 3:3-6). Words shape relationships, reputations and our own hearts.
What does the Bible say about gossip?
Scripture calls a gossip a talebearer or whisperer and warns that gossip separates close friends (Proverbs 16:28) and keeps strife burning (Proverbs 26:20). Paul lists whisperers and backbiters among the sins of a darkened mind (Romans 1:29-30). The cure is to speak to people, not about them. If you tend to grumble as well, see complaining.
How can I control my tongue?
Pray Psalm 141:3 each morning, listen before you speak (James 1:19), pause before you send a message, and deal with the anger or envy underneath (Matthew 12:34). James admits that no man can tame the tongue alone (James 3:8), so ask God daily for help.
Will we give account for our words?
Yes. Jesus said, "every idle word that men shall speak, they shall give account thereof in the day of judgment" (Matthew 12:36). That is sobering, but the same passage shows that a good heart brings forth good things (Matthew 12:35).
