Where is this verse in the Bible 'The power of life and death lies within the tongue'?

Answer 1

There is not a verse which matches this exactly, but here is one which contains a similar kind if idea:

James 3:1-12 (King James Version)1My brethren, be not many masters, knowing that we shall receive the greater condemnation.

2For in many things we offend all. If any man offend not in word, the same is a perfect man, and able also to bridle the whole body.

3Behold, we put bits in the horses' mouths, that they may obey us; and we turn about their whole body.

4Behold also the ships, which though they be so great, and are driven of fierce winds, yet are they turned about with a very small helm, whithersoever the governor listeth.

5Even so the tongue is a little member, and boasteth great things. Behold, how great a matter a little fire kindleth!

6And the tongue is a fire, a world of iniquity: so is the tongue among our members, that it defileth the whole body, and setteth on fire the course of nature; and it is set on fire of hell.

7For every kind of beasts, and of birds, and of serpents, and of things in the sea, is tamed, and hath been tamed of mankind:

8But the tongue can no man tame; it is an unruly evil, full of deadly poison.

9Therewith bless we God, even the Father; and therewith curse we men, which are made after the similitude of God.

10Out of the same mouth proceedeth blessing and cursing. My brethren, these things ought not so to be.

11Doth a fountain send forth at the same place sweet water and bitter?

12Can the fig tree, my brethren, bear olive berries? either a vine, figs? so can no fountain both yield salt water and fresh.

There is indeed a scripture which says this....Proverbs 18:21 King James Bible

Death and life [are] in the power of the tongue: and they that love it shall eat the fruit thereof.

Answer 2

This phrase is not a direct quote from The Bible but is often associated with the concept of the power of words as expressed in verses like Proverbs 18:21 which says, "The tongue has the power of life and death, and those who love it will eat its fruit."
