James 3:6–8

6 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 coursec of nature; and it is set on fire of hell. 7 For every kindd 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.
