James 3:5b-8
5 So also the tongue is a small part of the body, and yet it boasts of great things.

See how great a forest is set aflame by such a small fire! 6 And the tongue is a fire, the very world of unrighteousness; the tongue is set among our body’s parts as that which defiles the whole body and sets on fire the course of our life, and is set on fire by hell. 7 For every species of beasts and birds, of reptiles and creatures of the sea, is tamed and has been tamed by the human race. 8 But no one among mankind can tame the tongue; it is a restless evil, full of deadly poison.
