James 3:6

4 Behold 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.

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

And 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.

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

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

Do read the surrounding verses too, because the context often says more than a single verse.
